Experimental study of damage to ultra-high performance concrete slabs subjected to partially embedded cylindrical explosive charges

In this study, long and thin cylindrical charges were partially embedded in ultra-high-performance concrete (UHPC) and normal-strength concrete (NSC) slabs to investigate the damage characteristics of UHPC slabs subjected to explosions by conventional weaponry. The sizes of ejection and spalling craters were recorded after the experiment to compare the obtained data with the concrete slab damage characteristics predicted by current damage forecasting methods. The current damage forecasting methods were found to be unsuitable for the conditions considered in this study as they do not account for the effects of the explosive shape and depth of embedment (DOE) simultaneously. The results of the experiment using partially embedded charges indicated that the damage on the sides of the slabs decreased with decreasing slab thickness; the use of UHPC without fiber reinforcement instead of using NSC significantly increased the compressive strength but decreased the ability of the concrete structure to resist spalling damage; furthermore, a suggested estimation of the cone slope angle is 60° for theoretical analyses and the design of numerical simulation or field experiments.

Experimental Study on the Salt Freezing Durability of Multi-Walled Carbon Nanotube Ultra-High-Performance Concrete.

Ultra-high-performance concrete (UHPC) is a new type of high-performance cement-based composite. It is widely used in important buildings, bridges, national defense construction, etc. because of its excellent mechanical properties and durability. Freeze thaw and salt erosion damage are one of the main causes of concrete structure failure. The use of UHPC prepared with multi-walled carbon nanotubes (MWCNTs) is an effective method to enhance the durability of concrete structures in complex environments. In this work, the optimal mix proportion based on mechanical properties was obtained by changing the content of MWCNTs and water binder ratio to prepare MWCNTs UHPC. Then, based on the changes in the compressive strength, mass loss rate, and relative dynamic modulus of elasticity (RDME), the damage degree of concrete under different salt erosion during 1500 freeze-thaw (FT) cycles was analyzed. The changes in the micro pore structure were characterized by scanning electron microscope (SEM) and nuclear magnetic resonance (NMR). The test results showed that the optimum mix proportion at the water binder ratio was 0.19 and 0.1% MWCNTs. At this time, the compressive strength was 34.1% higher and the flexural strength was 13.6% higher than when the MWCNTs content was 0. After 1500 salt freezing cycles, the appearance and mass loss of MWCNTs-UHPC prepared according to the best ratio changed little, and the maximum mass loss was 3.18%. The higher the mass fraction of the erosion solution is, the lower the compressive strength and RDME of concrete after FT cycles. The SEM test showed that cracks appeared in the internal structure and gradually increased due to salt freezing damage. However, the microstructure of the concrete was still relatively dense after 1500 salt freezing cycles. The NMR test showed that the salt freezing cycle has a significant influence on the change in the small pores, and the larger the mass fraction of the erosion solution, the smaller the change in the proportion of pores. After 1500 salt freezing cycles, the samples did not fail, which shows that MWCNTs UHPC with a design service life of 150 years has good salt freezing resistance under the coupling effect of salt corrosion and the FT cycle.

Seismic Performance and Cost Analysis of UHPC Tall Buildings in UAE with Ductile Coupled Shear Walls.

The superior mechanical characteristics of ultra-high-performance concrete (UHPC) have attracted the interest of many researchers worldwide. Researchers have attempted to perform comparative analyses on the behavior of UHPC versus conventional and high-strength concrete, with their aim being to gain more insights into the difference between different types of concrete. However, the current state-of-the-art revealed no direct comprehensive comparisons between their behaviors in ductile coupled shear walls under seismic loading. This paper explores a comprehensive side-by-side comparison in terms of seismic behavior and cost analysis for four 60-story archetype buildings. The reference building was designed using high-strength concrete with a strength of 60 MPa. The other three archetype variations incorporated three different UHPC grades: 150 MPa, 185 MPa, and 220 MPa. The plan configuration and the lateral force-resisting system (LFRS) were chosen according to the most common practice in the UAE. The main objective is to report the effect of UHPC on the LFRS (ductile coupled shear walls). Moreover, a simplified initial cost analysis (materials and labor) design was performed. The findings of this paper indicate that the use of UHPC is capable of improving the seismic performance behavior of the lateral system as well as reducing the total initial costs.

Structural and buckling behavior of full-scale slender UHPC columns

Ultra-high performance concrete (UHPC) is a relatively new class of concrete and cementitious materials with much higher strength and durability than conventional concretes. The use of UHPC is currently expanding worldwide from bridge deck joints and connections to full components and larger applications. With the superior mechanical properties of UHPC, future UHPC columns in buildings and bridges will have compact cross-sections and smaller footprint. The main goal of this study is to provide experimental demonstration and reliable datasets of slender UHPC columns to validate current analytical procedures and inform future designs. This paper presents results and discussions from five full-scale UHPC columns (largest set of axially-tested UHPC columns to-date) at a 4 million-lb [∼18,000 kN] testing facility. The specific objectives are to investigate the structural and buckling behavior of slender UHPC columns under concentric axial loading, and assess the current ACI procedure for slenderness effects using the moment magnification method. When the actual material properties of UHPC and longitudinal bars are used for assessment, the ACI equations were found to overestimate the axial load capacity of slender columns by approximately 9%, on average. The study is concluded by design guidance and several recommendations for applying the moment magnification method for slender UHPC columns, which can be readily incorporated into future design codes.

Numerical investigation of hybrid UHPC columns subject to lateral impact

This paper presents extensive numerical and parametric studies on the dynamic performance of axially-loaded hybrid ultra-high-performance concrete (UHPC) columns subject to low-velocity impact loading. While existing studies have been performed on columns comprised fully of UHPC, the case of hybrid UHPC columns has not been fully explored. Hybrid columns involve the localised use of UHPC in combination with normal strength concrete (NSC) and can result in both performance and economic efficiencies. The present study uses Abaqus to develop a validated finite element (FE) model which allows exploration of key parameters such as impact location and energy, slenderness ratio and the length of the UHPC zone and their effect on hybrid column behaviour. It was found that localised adoption of UHPC at the predicted impact location significantly enhanced the performance and resulted in a change from brittle shear failure to flexural failure with minimal damage. The length of the UHPC segment was also found to have greater effect on columns with low reinforcement ratio. Meanwhile, the impact location was shown to have significant influence on the column response especially under a low pre-loading level. Hybrid columns experienced less displacement and higher plateau impact load under low impact energy. In comparison to the normal strength concrete column, the hybrid columns exhibited reduced mid-span displacement and increased impact load capacity which confirmed the ability of the UHPC segment to reduce the local damage resulting from the impact. In addition, in many cases, it was found that the application of higher pre-loading levels can provide an improvement in total impact performance of the hybrid columns. This is mainly attributed to the shifting of the pre-loading axis as a result of cracking at the top of the column ends. Finally, the presence of a UHPC segment with various lengths can change the location of the main (central) plastic hinge to the end of the UHPC segment, this reflects the ability of UHPC in improving the entire response of hybrid columns.

Effect of different fiber combinations and optimisation of an ultra-high performance concrete (UHPC) mix applicable in structural elements

In this study, Ultra-High Performance Concrete (UHPC) mix was optimised to expand its use in large-scale applications. Using alternative curing methods instead of heat treatment, it was aimed that UHPC will meet the required strength and workability criteria and thus be presented applicable solutions for widespread use of UHPC in engineering applications. Therefore, effect of aggregate type, fiber content, curing method, compacting method, cement type, water/cement ratio and aggregate granulometry on mechanical properties of UHPC was investigated. Compressive strength, flexural tensile strength, splitting tensile strength, pull-out behaviour, modulus of elasticity and toughness values of the UHPC series were determined. Standard water curing (compared to wet hessian application) increased the compressive strength by 11.2% and the flexural tensile strength by 19%, while the inclusion of hybrid fibers (compared to the use of a single type of fiber) increased the compressive strength by 16.7% and the flexural tensile strength by 48%. Type of aggregate was found very effective on flexural tensile strength as well, and it provided additional ductility by increasing the matrix strength. In cases where heat treatment is not available, it was observed that the required strength criteria can be met with standard water curing as well. UHPC with a compressive strength of 170 MPa, which has excellent workability, was developed. As a result of the study, optimum solutions were proposed for the widespread use of UHPC in the precast industry.

Flexural strength prediction models of non-prestressed Ultra-High Performance Concrete (UHPC) components

The use of Ultra-High Performance Concrete (UHPC) has been growing rapidly in the past two decades because of its superior mechanical and durability properties compared to conventional concrete (CC). Flexural strength prediction models of CC components underestimate the flexural strength of non-prestressed UHPC components as they ignore the tensile strength of concrete and assume different stress–strain relationships and failure mode from those of UHPC. The objective of this paper is to evaluate the current flexural strength prediction models of non-prestressed UHPC components using test data collected from the literature and validate them using experimental data of a UHPC ribbed slab tested in flexure. Measured and predicted flexural strengths are compared at different curvatures. Evaluation results indicated that neglecting the tensile strength of UHPC significantly underestimates the flexural strength of non-prestressed UHPC components. Peak moment curvature of non-prestressed UHPC components is significantly smaller than ultimate moment curvature. In addition, the differences among idealized stress–strain relationships of UHPC in compression and tension do not have significant effect on the predicted flexural strength.

Investigations on Integrally Lifted Prefabricated High-Performance Concrete Cap Beams

This research proposes two new types of prefabricated high-performance concrete cap beam structures, which solve the problem that the traditional large cap beam needs to be split into two to three parts during assembly construction, and the construction efficiency is reduced. Using new materials such as ultra-high performance concrete (UHPC) and new technology such as high-performance composite structure, two new types of cap beams are studied. Taking prestressed concrete cap beams as the control group, the calculation model of each cap beam is established, and then the mechanical performance of each cap beam is tested and analyzed. At the same time, the self-weight, cross-sectional size, quantity of prestressed steel bars, and manufacturing material cost of each cap beam are also analyzed and compared, and the applicability of each cap beam is given. The research results show that compared with ordinary concrete, the use of UHPC can significantly improve the mechanical performance of the cap beam, reduce the cross-sectional size of the cap beam, and reduce the self-weight of the cap beam. Calculation results show that the steel-UHPC composite cap beam can achieve the smallest lifting weight. In summary, the two new prefabricated high-performance concrete cap beams proposed in this paper can significantly reduce the self-weight of the cap beam and improve the construction efficiency.

An Enhanced UHPC-Grout Shear Connection for Steel-Concrete Composite Bridges with Precast Decks

This article develops an enhanced UHPC-grout shear connection for steel-concrete composite bridges with precast decks. The primary improvement is the use of ultra-high performance concrete (UHPC) as the connection grout. To validate the constructability and the mechanical performance of the new connection, two series of experimental tests (including grouting tests and push-out tests) were conducted. Results from the grouting tests show that both the pressure grouting method and the self-levelling grouting method are applicable to inject the UHPC grout into the channel void of the connection. Results from the push-out tests indicate that the advanced properties of UHPC allow for a significant improvement of the shear resistance of the adhesive connection over traditional cementitious grouts. The ultimate shear capacity of the adhesive connection is controlled by the interface shear strength between the embossed steel and the UHPC grout, with a cohesion value of approximately 5.87 MPa. Meanwhile, the residual frictional resistance can be taken as approximately one-half of the ultimate resistance. The results of the finite-element analysis show that the trilinear model is reasonable to simulate the shear-slip laws of the embossed steel-grout interface and the rough concrete-grout interface.

Numerical investigation of non-shear-reinforced UHPC hybrid flat slabs subject to punching shear

Flat slabs are commonly used in the construction of multi-storey buildings due to their ease of placement and installation, relatively short construction time, minimal structural floor depth and economic credentials. However, flat slabs are vulnerable to punching shear, a failure mode that typically occurs without any warning at slab-column connections. While various methods exist to improve punching shear capacity, the use of ultra-high performance concrete (UHPC) offers a highly buildable alternative to use of shear reinforcement in normal strength concrete (NC). However, UHPC is an expensive material and recent research has focussed on its partial use in column zones only, with NC elsewhere i.e. hybrid NC/UHPC. In this paper, a non-linear finite element (FE) model using ABAQUS was developed to simulate the punching shear performance of hybrid NC/UHPC flat slabs without shear reinforcement. The FE model was validated against experimental results from the literature. The validated model was then used to investigate the influence of slab thickness, column size, UHPC area and UHPC compressive strength. The results show that punching shear capacity of the slabs increases with the area of the UHPC zone. Additionally, the ratio of concrete compressive strength of UHPC to that of NC has a significant effect on the behaviour of the hybrid slabs which should be accounted for in future design guides. In order to understand the performance of existing design guides and codes in this context, a comparison between FE results and code predictions is also presented. The results suggest that the code models including ACI 318-14, Eurocode2 and Model Code 2010 cannot accurately estimate the punching shear capacity of reinforced UHPC slabs and hybrid NC/UHPC slabs. A modification to the existing ACI equation is proposed which yields accurate predictions for reinforced UHPC and hybrid slabs.

Mechanical Behavior of Ultrahigh-Performance Concrete Tunnel Lining Segments.

Ultrahigh-performance concrete (UHPC) is a novel material demonstrating superior mechanical, durability and sustainability performance. However, its implementation in massive structures is hampered by its high initial cost and the lack of stakeholders’ confidence, especially in developing countries. Therefore, the present study explores, for the first time, a novel application of UHPC, incorporating hybrid steel fibers in precast tunnel lining segments. Reduced scale curved tunnel lining segments were cast using UHPC incorporating hybrid 8 mm and 16 mm steel fibers at dosages of 1%, 2% and 3% by mixture volume. Flexural and thrust load tests were conducted to investigate the mechanical behavior of UHPC tunnel lining segments thus produced. It was observed that the flow of UHPC mixtures decreased due to steel fibers addition, yet steel fibers increased the mechanical and durability properties. Flexural tests on lining segments showed that both the strain hardening (multiple cracking) and strain softening (post-peak behavior) phases were enhanced due to hybrid addition of steel fibers in comparison with the control segments without fibers. Specimens incorporating 3% of hybrid steel fibers achieved 57% increase in ultimate load carrying capacity and exhibited multiple cracking patterns compared to that of identical UHPC segments with 1% fibers. Moreover, segments without fibers incurred excessive cracking and spalling of concrete at the base under the thrust load test. However, more stable behavior was observed for segments incorporating steel fibers under the thrust load, indicating its capability to resist typical thrust loads during tunnel lining field installation. This study highlights the potential use of UHPC with hybrid steel fibers for improved structural behavior. Moreover, the use of UHPC allows producing structural members with reduced cross-sectional dimensions, leading to reduced overall structural weight and increased clear space.

Development of a precast prestressed concrete through‐girder system for shallow bridge structures

AbstractThis paper proposes an innovative precast through‐girder system that can be used in shallow bridge structures. It discusses various components of the through‐girder system, including the edge (through) girders, transverse beams, and longitudinal and transverse connections. The through girders are made of precast concrete box beam segments that are spliced longitudinally through posttensioning. The precast prestressed transverse beams span between the through‐girders involving the use of transverse posttensioning. An important feature of this system is to implement ultra‐high performance concrete (UHPC) at the all joints. The use of UHPC allows to minimizing the joint width and achieving superior durability. A numerical example is presented to demonstrate the analysis and design of the through‐girder bridge superstructure accounting for both high‐performance concrete (HPC) and UHPC options. The UHPC superstructure option can reduce the sizes of the structural members and allow to enhancing the structural performance.

A preliminary study on the development of the normal concrete-UHPC composite beam via wet casting

Ultra-high-performance concrete (UHPC) is an innovative cementitious composite containing steel fiber reinforcement that can improve the behavior of structural elements thanks to its high strength and improved ductility properties. The mix design that provides these superior properties of UHPC also makes it a high-cost material. For this reason, the use of UHPC in parts where it contributes more significantly to the performance of the structural elements will lower down the costs and reduce the negative environmental effects caused by high cement content. In this preliminary study, the production of normal concrete (NC)-UHPC reinforced concrete (RC) composite beams by wet-on-wet casting was investigated by producing mini-RC beams. In the production of mini-RC beams, normal mortar (NM) and self-compacting mortar (SCM) mixtures were used to represent an NC. The results showed that in the production of NC-UHPC composite beams, the mixtures should have different rheological properties depending on the order of the layers. Increasing the total thickness of the UHPC layer enhanced the initial and yield stiffnesses as well as the peak loads. UHPC layer with thicknesses of 15 mm in tension zone, 30 mm in tension zone, and 15+15 mm in tension+compression zone led to the load-carrying capacity increment ratios of 20%, 34.6%, and 24.3%, respectively. However, increasing the thickness of the UHPC layer in the composite beams, especially more than 15 mm, reduced the ductility ratio and energy absorption capacity. Optimizing the tensile reinforcement ratio in UHPC layers can overcome the drawbacks in the ductility.

Development length of sand-coated GFRP bars embedded in Ultra-High performance concrete with very small cover

The development length of sand-coated glass fiber reinforced polymer (GFRP) reinforcing bars embedded into ultra-high performance concrete (UHPC) with very small cover is evaluated in this study using twenty-eight notched beam specimens tested in flexure. The parameters included the type and percentage of short fibers in the UHPC mixture, namely 2% and 4% steel fibers and 2% and 3% polyvinyl alcohol (PVA) fibers. The embedment length of a 17.2 mm diameter (db) GFRP bar, a widely used size, was varied from 4db to 16db. The study focused on a very small clear concrete cover of 1.0db to simulate applications that would optimize the use of UHPC, taking advantage of its superior strength. The specimens experienced splitting bond failure as expected. The average bond strength (τu) was higher in UHPC with steel fibers than PVA fibers. It also increased with fiber content but reduced with embedment length. Consequently, the development length (Ld) was smaller in UHPC with steel fibers than PVA fibers and was also reduced as fiber content increased. The Ld values for UHPC with 4% steel, 2% steel, 3% PVA and 2% PVA were 20db, 29db, 35db and 55db, respectively. ACI440.1R-15 and CAN/CSA S806-12 design equations provided very conservative estimations for Ld, by factors of 1.5–5.7. An alternative simple equation has been suggested for Ld.

Hydration heat, strength and microstructure characteristics of UHPC containing blast furnace slag

Ultra-high performance concrete (UHPC) is an innovative cement-based composite with high mechanical performance under tensile and compressive loads, extremely low permeability, and excellent durability. Because of these features, UHPC has the potential to contribute to the development of new architectural perspectives and structural systems with prolonged service life; therefore, it is anticipated that the use of UHPC in cast-in-situ applications will increase in the near future. As a result of its high Portland cement dosage, the hydration heat of UHPC can be relatively high compared to that of conventional concrete. Thus, ground granulated blast furnace slag (GGBS) can be used in UHPC formulation for reducing Portland cement dosage thereby limiting hydration heat while also addressing ecological and engineering concerns. In the scope of this study, the effects of GGBS replacement (0%, 30%, and 60%) on the hydration heat, strength, and microstructural characteristics of UHPC were studied. Results showed that GGBS-bearing UHPCs are more sensitive to ambient temperature in respect to cumulative heat. 60% GGBS replacement reduced cumulative heat release by 36% and 28% at 20 °C and 35 °C respectively. So, the benefit of GGBS on reducing hydration heat is less pronounced in hot weather. Performance differences in strength depending on the replacement ratio were only noticeable on the first day of curing. Prolonged curing time and fiber inclusion eliminated strength differences. Microstructural investigations indicated that Ca(OH)2 can be lowered up to 0.5%, and the Ca/Si ratio of the C–S–H phase was reduced below the value of 1.0 after 90 days of curing as a result of GGBS replacement.

Innovative Approach to Repair Corroded Steel Piles using Ultra-High Performance Concrete

Steel H-piles are a common structural system in existing bridges. Many steel H-piles have been corroded as a result of severe weather and acid/alkaline salt exposures, causing a reduction in the axial load capacity. This paper experimentally investigates the use of ultra-high performance concrete (UHPC) encasement as a novel repair method for corroded steel H-pile. UHPC displays better tensile strength, early compressive strength, workability, and durability compared with conventional concrete. The proposed repair is used to bridge the corroded section in H-pile using either a cast-in-place or precast UHPC elements. A series of push-out tests was conducted on eight full-scale piles to assess the axial force that can be transferred through shear studs and bond between the UHPC and steel piles. The test parameters include the type of casting of the UHPC, that is, cast-in-place versus precast elements, thickness and shape of the UHPC elements, an inclusion of carbon fiber reinforced polymer (CFRP) grid, number and grade of bolts, an inclusion of washer, and applying torque on the bolts. The experimental work demonstrated that the UHPC precast repair can be easily implemented. Moreover, using 57 mm (2.25 in.) thick UHPC plates reinforced by two layers of the CFRP grid was capable of transferring up to 81% of the squash load of the H-pile.

Seismic performance of a novel interior precast concrete beam-column joint using ultra-high performance concrete

In traditional precast reinforced concrete (RC) frame structures, the reinforcement details are usually complex in the joint zone, which makes the fabrication process difficult and thus affects the construction quality and speed. Ultra-high performance concrete (UHPC) exhibits substantially higher shear resistance and bond strength than normal concrete due to its much larger compressive and tensile strengths. As a result, the application of UHPC can significantly help reducing the amount of stirrups and anchorage length of the longitudinal bar in the joint zone of precast RC frames, which can obviously simplify the joint construction. This paper presents the cyclic tests of four interior precast UHPC/RC composite beam-column joints to evaluate quantitatively the effect of replacing the normal concrete by UHPC in the joint zone. Considering that the condition of steam curing is difficult to achieve in the actual construction environment, the non-steam-cured UHPC was adopted and proved to exhibit adequate compressive (>120 MPa) and tensile strength (>7 MPa) with the ultimate tensile strain larger than 1%. The main variables in this study are the anchorage methods, anchorage lengths and stirrup ratios in the joint zone. The cyclic load tests demonstrate that the cast-in-situ UHPC can work well with the precast concrete and there is no need of stirrups in the UHPC joint zone. With the use of UHPC instead of normal concrete, the anchorage length of the beam straight and headed bars can be decreased to 16db and 8.1db, respectively. Therefore, the application of UHPC in the joint zone is practicable and can greatly ease the fabrication process, especially with the use of headed bars.

Comparative studies of the effect of ultrahigh-performance concrete and normal concrete as repair materials on interfacial bond properties and microstructure

This study aims to investigate the effects of repair materials such as ultra high-performance concrete (UHPC) and normal concrete (NC) on the bond performance and microstructure between a concrete substrate and the repair materials. Specifically, C25, C35, and C45 concretes were used as the substrate materials, and their surfaces were treated with high-pressure water. C45 and UHPC were used as the repair materials. Bond properties were evaluated through slant shear tests with various slant angles and splitting tensile strength tests. Cohesion strength and internal friction were obtained via the slant shear test at three angles using the Mohr–Coulomb approach to reflect the differences between different repair materials. In addition, combining the splitting tensile strength and slant shear tests at three angles, bond failure envelopes were obtained using second-order polynomial and bi-linear models, which can reflect the bond behaviour of repair materials more effectively. The results of the study indicate that UHPC combined with concrete substrates exhibit good interfacial bond performances compared with NC repair materials. Compared with NC, the interface transition zone between UHPC and a substrate is denser, stronger, and more uniform, which results in good bond performance. Using second-order polynomial and bi-linear models, the UHPC repair material are more beneficial to the full utilisation of the mechanical properties of the substrate compared with the NC repair materials. Therefore, it is envisaged that the use of UHPC combined with the high-pressure water treatment of a substrate surface will provide an effective repair.

Study on Coupling of Glass Powder and Steel Fiber as Silica Fume Replacement in Ultra-High Performance Concrete: Concrete Sleeper Admixture Case Study

To investigate the substitution of silica fume (SF) with the coupling of glass powder (GP) and steel fiber (STF), a concrete sleeper admixture (CSA) contains SF is considered as the reference concrete admixture. The use of high SF content in CSAs has negative effects on concrete rheology. Furthermore, it decreases the extensive use of ultra-high performance concrete (UHPC) in concrete markets that can mainly be caused by the limitation in available resources and the high cost of SF production. The substitution of SF with GP is insufficient; therefore, the possibility of using the coupling of GP and STF as a SF replacement has been researched. In this regard, 0.5%, 1 % and 1.5% steel fiber by concrete volume and 5%, 10% and 15% glass powder and silica fume by weight of cement content have been investigated. It is found that concrete admixture with the coupling of STF and SF improves all the characteristics of the concrete. Additionally, the coupling effects of GP and STF are better than that of the SF and STF. Based on the synthetic consideration of the performance and cost, the combination of 10% GP and 1.5% STF is optimal in case of CSA mechanical performance.

Considerations on the use of ultra-high performance concrete for water tanks

The development of ultra-high strength and high performance concrete is a relatively new field in the profile industry. The last 150 years have shown that, despite getting more and more resistance, the practical applications have been too many times due to innovations in materials science. This phenomenon seems to be caused by the increased costs per unit of volume, as resistance increases, as well as a cautious retention of using new materials in practical applications. The present study aims to be an encouragement of practical structural applications by presenting an Ultra High Performance Concrete (UHPC), developed with locally available materials. As it is known, concrete is the main building material worldwide. In the last decades, his leadership position has been strengthened by the constant concern of the researchers and by obtaining the various types of concrete with increasing performances from the point of view of the fresh and hardened state, obtaining special structural applications.
