Experimental investigations of dry-dry timber-concrete composite notched connections designed for disassembly

Timber-Concrete Composite (TCC) decks offer an efficient, and environmentally friendly alternative to conventional concrete slabs. Traditionally the concrete is cast directly onto the timber with a permanent connection arrangement that does not allow non-destructive disassembly at end-of-service-life. This will prevent the reuse of the materials and ultimately decrease the extent of the environmental benefit. This paper presents a deconstructable dry-dry notched connection made from fully prefabricated timber and concrete elements. The concept was investigated through 30 experimental pure-shear push-off tests, where various design parameters, such as prestressing degree, fastener placement, and notch length, were varied. The experimental results indicate that the new connection exhibits the same stiffness characteristics as a traditional wet-dry notched connection. Five different failure modes were observed in the series, and experimental measurements such as Digital Image Correlation and fastener force measurement provided insight into the connection behavior during failure. Two rigid-plastic upper bound solutions were established to estimate the load-carrying capacity for two of the observed concrete failures, and a satisfactory agreement with the test results was obtained. In conclusion, the experimental results indicated that dry-dry notched connections are feasible for achieving a more environmentally friendly TCC structure.

The floor slab is designed to behave as a diaphragm during an earthquake (Ultimate limit states). Floor slabs are designed in such a way that deflection and vibration are within serviceability limit states. The criteria for the maximum plate deflection are used according to SNI 2847-2019.
 The analysis carried out is to compare the work of conventional concrete floor slabs and floor slabs as a result of the output analysis from the SAP 2000 software. The goal to be achieved in this study is to analyze the structure of conventional concrete slabs with the results of computer software to obtain the difference in plate reinforcement spacing so that it will be obtained optimal distance. From the conclusions of the research that has been carried out, it is obtained that conventional concrete floor slabs are narrower than the results of the spacing of the reinforcement from the software results, for the SAP output the spacing is more tenuous. Based on these results, for the selection of reinforcement spacing, it is recommended to use the smallest spacing. obtained by Manual analysis is at moment 11 of Mu = 11.109 kNm with a diameter used for Ø 10-100 mm reinforcement, while analysis with SAP 2000 software is obtained at moment 11 for M11 = 9.876 kN.m with a diameter used for plain reinforcement Ø10-150 .Based on the plate moment obtained by Manual analysis is at moment 22 of Mu = 7.454 kNm with a diameter used for reinforcement Ø 10-150 mm, while analysis with SAP 2000 software is obtained at moment 22 of Mu = 6.507 kN.m with a diameter used plain reinforcement Ø10-200.

Modeling and Simulation of Mechanical Performance in Textile Structural Concrete Composites Reinforced with Basalt Fibers

This investigation deals with the prediction of mechanical behavior in basalt-fiber-reinforced concrete using the finite element method (FEM). The use of fibers as reinforcement in concrete is a relatively new concept which results in several advantages over steel-reinforced concrete with respect to mechanical performance. Glass and polypropylene (PP) fibers have been extensively used for reinforcing concrete for decades, but basalt fibers have gained popularity in recent years due to their superior mechanical properties and compatibility with concrete. In this study, the mechanical properties of basalt-fiber-reinforced concrete are predicted using FEM analysis, and the model results are validated by conducting experiments. The effect of fiber-volume fraction on the selected mechanical performance of concrete is evaluated in detail. Significant improvement is observed when the loading is increased. There are superior mechanical properties, e.g., load bearing and strain energy in basalt-fiber-reinforced concrete as compared to conventional concrete slabs reinforced with gravel or stones. The results of the simulations are correlated with experimental samples and show a very high similarity. Basalt-fiber-reinforced concrete (BFRC) offers a lightweight construction material as compared to steel-fiber-reinforced concrete (SFRC). Further, the problem of corrosion is overcome by using this novel fiber material in concrete composites.

Multi-gene genetic programming extension of AASHTO M-E for design of low-volume concrete pavements

The American Association of State Highway and Transportation Officials Mechanistic-Empirical Pavement Design Guide (AASHTO M-E) offers an opportunity to design more economical and sustainable high-volume rigid pavements compared to conventional design guidelines. It is achieved through optimizing pavement structural and thickness design under specified climate and traffic conditions using advanced M-E principles, thereby minimizing economic costs and environmental impact. However, the implementation of AASHTO M-E design for low-volume concrete pavements using AASHTOWare Pavement ME Design (Pavement ME) software is often overly conservative. This is because Pavement ME specifies the minimum design thickness of concrete slab as 152.4 ​mm (6 in.). This paper introduces a novel extension of the AASHTO M-E framework for the design of low-volume joint plain concrete pavements (JPCPs) without modification of Pavement ME. It utilizes multi-gene genetic programming (MGGP)-based computational models to obtain rapid solutions for JPCP damage accumulation and long-term performance analyses. The developed MGGP models simulate the fatigue damage and differential energy accumulations. This permits the prediction of transverse cracking and joint faulting for a wide range of design input parameters and axle spectrum. The developed MGGP-based models match Pavement ME-predicted cracking and faulting for rigid pavements with conventional concrete slab thicknesses and enable rational extrapolation of performance prediction for thinner JPCPs. This paper demonstrates how the developed computational model enables sustainable low-volume pavement design using optimized ME solutions for Pittsburgh, PA, conditions.

Plastic Hinge Length Mechanism of Steel-Fiber-Reinforced Concrete Slab under Repeated Loading

The plastic hinge is the most critical damaging part of a structural element, where the highest inelastic rotation would occur. In particular, flexural members develop maximum bending abilities at that point. The current paper experimentally investigates the influence of steel fiber reinforcement at the plastic hinge length of the concrete slab under repeated loading, something which has not been reported by any researcher. Mechanical properties such as compressive strength and tensile strength of M20-grade concrete that are used for casting specimens are tested through the compressive strength test and the split tensile strength test. Six different parameters are considered in the slab while carrying out this study. First, the conventional concrete slab and then the steel-fiber-reinforced slab were cast. The plastic hinge length of the slab was calculated through different empirical expressions taken from methods by Baker, Sawyer, Corley, Mattock, Paulay, Priestley and Park. Finally, the steel fiber was added as per methods detailed by Paulay, Priestley and Park in the plastic hinge length mechanism in the concrete slab at 70 mm and 150 mm separately. The results arrived through experimental investigation by applying repeated loads to the slab, indicating that steel fibers used at critical sections of plastic hinge length provide similar strength, displacement, and performance as that of the conventional RCC slab and fully steel-fiber-reinforced concrete slabs. Steel fiber at a plastic hinge length of slab has a better advantage over a conventional slab.

Force‐Deformation Study on Glass Fiber Reinforced Concrete Slab Incorporating Waste Paper

This study inspects the viability of engaging the discarded paper wastes in concrete by varying the volume proportions from 0%–20% with each 5% increment in replacement of the weight of cement. A physiomechanical study was conducted, and the results were presented. A glass fiber reinforced rectangular slab with a longer span (ly) to shorter span (lx) ratio of (ly: lx) 1.16 was cast with optimum replacement of waste‐paper mass and compared the force‐deformation characteristics with the conventional concrete slab without waste paper. The optimum percentage of discarded papers for the replacement of cement is 5%. Also, the results imply that the compressive strength at the age of 28 days is 30% improved for the optimum replacement. Based on the outcomes of the investigation, it can be inferred that the compressive strength gets progressively reduced if the volume of the discarded paper gets increases. The incorporation of glass fibers improves the split and flexural strength of the concrete specimens considerably. The ultimate load‐carrying capacity of the glass fiber reinforced waste paper incorporated concrete slab measured 42% lower than that of the conventional slab. However, development of the new type of concrete incorporating waste papers is the new trend in ensuring the sustainability of construction materials.

Experimental study on replacing sand by M−Sand and quarry dust in rigid pavements

In modern days of construction, many materials have alternatives that satisfy the characters of the replaced material. The present study is made to identify the replacement material for river sand in construction activities, as it is being difficult to acquire river sand in the coming days. Scarcity of river sand is on line. Materials namely Manufactured -sand (M−sand) and quarry dust is considered in this experimental study as100% replacements for river sand which is being used as fine aggregate (FA) in concrete. Characteristics like temperature difference, skid resistance and fatigue behavior of M−sand modified concrete, quarry dust modified concrete and conventional concrete are studied at optimum quantity (1.5 %) of super plasticizer. The mechanical properties of the modified concrete and conventional concrete were compared. From the results, it is observed that, the M −sand modified concrete seen better skid resistance of 12 mm and 11 mm higher as compared to quarry dust modified concrete on dry surface and wet surface respectively. Similarly, it is seen that 16 mm and 12 mm higher skid resistance than compared to conventional concrete on a dry surface and wet surface respectively. Moreover, the fatigue life of M−sand modified concrete is more than quarry dust modified concrete and conventional concrete. From the temperature readings it is observed that there is no significant variation in temperature differences between top and bottom of the slabs, the observed temperature readings are 12.1⁰, 11.6⁰C and 11.1⁰C in conventional concrete slab, quarry dust concrete slab and M−sand concrete slab respectively. However these values are less than the maximum value specified by code.

Reinforced Concrete Slab with Added Steel Fibers for Engineering Application: Preliminary Experimental Investigations

The application of steel fiber as added materials in a plain concrete shows many potential benefits in improving structural properties namely tensile and flexural strength. The plain concrete with steel fibers added is said to be effective for both short and long terms duration based on its characteristics mainly size, shape, volume, and distribution. Such potentials have made it a material worthy to be further studied. This research was conducted to assess the strength of a plain concrete with the addition of steel fibers in the conventional concrete slab. Several testings were conducted to determine the strength characteristic (compressive and flexural) of the control sample; conventional reinforced concrete (RC) and reinforced concrete with steel fibers added (RCSF). In this study, the commercial steel fibers taken from Dramix which is categorised under 5D-Type was added during the concrete mixing processes according to the three different percentages of 0.5%, 0.75% and 1.0%. Obtained result shows that the concrete with steel fibers added (0.5%) had the highest compressive strength while both reinforced concrete and concrete with 0.75% addition of steel fibers showed almost similar flexural strength value. Deflection testing was conducted on both RC slab and RCSF slab via Three-point bending test. It is found that the RC slab showed a higher mid-span deflection rate. Furthermore, result from the physical observation and measurement for crack propagation evaluation shows that RC slab had a wider cracking gap compared to RCSF. In a nutshell, steel fibers in plain concrete gives several advantages and provide an alternative for the construction practitioner in minimizing the construction cost while maintaining the quality and reducing the cracking problem mainly due to the structural properties of concrete.

Performance of crumb rubber concrete composite-deck slabs in 4-point-bending

A composite slab reinforced by profiled steel deck is a structural system where the longitudinal shear resistance between the steel deck and the concrete is the critical factor that governs the member capacity of the slabs under shear and/or flexural loads. Partially replacing concrete sand by crumbed rubber particles derived from used tyres to form crumb rubber concrete (CRC) can adversely affect the concrete mechanical characteristics; however, the plastic energy absorption and ductility of CRC have been shown to be improved. This paper presents an experimental study of large-scale composite slabs made of CRC or conventional concrete (CC) at similar compressive strength of 25 MPa that were tested under 4-point bending. Different shear spans and loading schemes were applied and tested in this study. The slabs were all 130 mm thick and had 3400 mm full span (800 mm shear span) for long slabs and 1800 mm full span (400 mm shear span) for short slabs. The overall performances, load carrying capacity, end-slippage, and interaction with steel of the tested CRC slabs were comparable or even better than those of the corresponding CC slabs, which indicated the viable substitution of CRC in composite slabs.

Experimental Investigation into Flexural Performance of Reinforced Profiled Steel Decking

Cold-formed profiled steel decking composite slab is one of the most widely used system of slab after conventional concrete slab for building structure. It is cost effective, straightforwardly designable and readily available in the market for construction. However due to modern architectural desire of large span building, this system weakness that is the requirement of temporary propped support may have an impact toward its cost effectiveness. Generally more propped support are required with the increase of slab span design.This paper present the result of laboratory test on the behavior of reinforced profiled steel decking under loading to increase the span for unpropped composite slabs construction. The load capacity of the steel decks was amplified by reinforcing cold formed C channel on the top flange of steel decks. The experimental program comprises 12 full-scale tests of three length with a set of modification of profiled steel decking using cold formed C channel.The result shown experimental evidence of the role played by the cold formed C channel on altering the cross section properties which supporting the bending capacity of the steel decks. The flexural response of the steel deck was examined using the LVDT instruments to capture the deformation at three points. The finding delivered by the experimental data for the performance of reinforced profiled steel decking are set as the base for the future verification of finite element model.

Design and performance of low shrinkage UHPC for thin bonded bridge deck overlay

The service life of bonded overlay materials used for bridge deck rehabilitation is affected by shrinkage of the overlay and bond between the overlay and substrate. There is a growing interest in using ultra-high performance concrete (UHPC) for thin bonded overlays. However, UHPC can exhibit high autogenous shrinkage leading to cracking under restrained conditions. This study investigated the synergistic effect of using pre-saturated lightweight sand (LWS) and a CaO-based expansive agent (EA) to mitigate shrinkage of UHPC. Five non-proprietary UHPC mixtures, a latex-modified concrete (LMC), and a conventional concrete (CC) were tested for material properties, including pore-size distribution, hydration kinetics, and bond strength. The mixtures were used to cast 16 bonded overlay slab specimens measuring 1 × 2 m with overlay thicknesses of 25, 38, and 50 mm. In-situ variations of strain, temperature, and relative humidity of overlay materials as well as cracking and overlay-substrate bond strength were monitored for 27 months. Test results indicated that the optimum UHPC made with 5% EA and 35% LWS had a relatively low autogenous and drying shrinkage of 190 and -310 με, respectively, at 28 d and the highest bond strength (3.1 MPa at 28 d). Such values were −520 and −520 με and 2.35 MPa, respectively, for UHPC made without any EA and LWS, and 20 and -475 με and 2.75 MPa, respectively, for the mixture prepared with 35% LWS. No cracking was observed in UHPC overlay slab specimens, whereas the CC and LMC overlays started cracking after approximately half a year. The increase in overlay thickness reduced crack density of the CC and LMC slabs. The optimum UHPC mixture made with 35% LWS and 5% EA had positive in-situ strain of 45 and 200 με over the 27-month testing period, indicating that the overlay was in compression. Direct pull-off strength of the UHPC was higher that of the LMC and CC mixtures and failure occurred in the CC substrate compared to the interface for the CC and LMC overlays.

Flexural behaviour of basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars

In this paper, the flexural behaviour of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars are studied and compared with slabs made with steel rebars. The optimum percentage of basalt is 0.3% for 50mm length basalt fibres. Due to high particle packing density in concrete made with basalt fibre micro cracks are prevented due to enhanced fatigue and stress dissipation capacity. Addition of basalt fibres to enhances the energy absorbtion capacity or toughness thereby enhancing the resistance to local damage and spalling. Addition of basalt fibres controlled the crack growth and crack width. Load at first crack of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is more than M30 grade conventional concrete slabs made with steel rebars because the with addition of basalt and BFRP bars will make either the interfacial transition zone (ITZ) strong or due to bond strength of concrete slabs made with basalt fibre reinforced polymer rebars. The ultimate strength in M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is more than conventional concrete slabs made with steel rebars. Deflection at the centre of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is almost double than the conventional concrete slabs made with steel rebars. Toughness indices evaluated for M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars indicates that basalt fibre and BFRP bars will enhance the energy absorbtion capacity of slabs.

Case Study of the Structural Performance of Composite Slabs with Low Strength CRC Delivered by Concrete Truck

Concrete mixing in laboratory conditions has a high level of quality control enabling it to achieve the designed workability and strength by accurately controlling the material quantity, mixing sequence, and mixing time. However, concrete mixing in construction sites or plants can suffer from some unpredictable situations, especially when implementing a newly designed concrete mix with uncommon materials in large-scale projects. Crumb Rubber Concrete (CRC) is a class of concrete that is formed by replacing conventional concrete (CC) fine aggregate by crumb rubber made from scrap tyres. CRC is not a completely new concrete class, as it has been researched in the laboratory level for a while. However, mixing CRC in industrial concrete plants and pouring it on-site, has had very limited implementation in Australia. This paper presents a case study of low-strength truck-delivered CRC poured on large-scale composite slabs. The slabs were reinforced by 0.75 mm-thick BONDEK profiled steel sheets and were tested under 4-point bending load. The variables in this study were the concrete material (CC and CRC), compressive strength (10, 20, and 25 MPa), the use of crack inducers (with and without), and the length of shear span (long and short). The low-strength CRC slabs were tested and compared with CC and CRC slabs having satisfactory strength. The results showed that, 30 % reduction in concrete compressive strength did not affect the load carrying capacity of composite slabs under bending, and slabs with 66 % reduction in concrete strength achieved 75 % of the flexural performance of that in conventional concrete composite slabs. This indicated that the flexural behaviour of composite slabs does not depend only on concrete compressive strength, and that the substitution of low-strength CRC in composite slabs can achieve a satisfactory flexural performance.

Bubble Deck Slab as an Innovative Biaxial Hollow Slab – A Review

Slab is the most important member in any building structure which consume large amount of concrete. The slab self-weight is large due to large consumption of concrete in producing slab. Therefore, bubble deck slab is an innovative and newly designed biaxial hollow slab system that had been introduced in order to overcome this problem. Bubble deck slab is a revolutionary method which was developed by Jorgen Bruenig from Denmark in the 1990s. The bubble deck slab had been designed and constructed with plastic hollow bubbles in the middle part of slab to eliminate the concrete which does not perform any structural function and at the same time reducing the slab self-weight. Thus, the self-weight of bubble deck slab can be reduced about 30-50% than conventional concrete slab; that can reduce the loads acting on columns, walls and foundations. Finally, the use of bubble deck slab can give many benefits as compared to conventional concrete slab such as improve the structural performance of slab, reduce the materials and cost, efficiency and faster construction time, and it is also a green product. The aim of this paper is to give some of the reviews from previous studies related to bubble deck slab.

Durability Properties on Marine Algae Concrete

Investigation of marine algae had its progress, due to chemical reaction with cement as a result nature gets affected by contamination and thus the inclusion of algae in the concrete found to control the destructive reactions. Algae are natural congenial which adds to the monetary of the concrete and, in the meantime, there is a decline of the wastes. Durability of concrete assumes an essential job in concrete structures. Durability of concrete might be characterized as the capacity of cement to withstand weathering activity and acid attack by retaining its ideal building properties. There are different materials utilized in the concrete to increase durability property. In this investigation, marine brown algae was utilized as added substance with concrete. A fixed water to cement ratio (W/C = 0.5) for M25 grade concrete was adopted with different marine brown algae percentages at 2%, 5% and 8%. The outcome demonstrates that 8% marine algae concrete performed well when contrast with traditional concrete. Deflection behaviour test established that thecrucial load limit of ideal mix concrete slab was found to be higher than the customary conventional concrete slab.

Alleviating urban heat island effect using high-conductivity permeable concrete pavement

Abstract This paper investigated the potential of using high-conductivity permeable concrete pavement in alleviating urban heat island (UHI) effect in both dry and wet conditions. The high-conductivity permeable concrete was prepared by adding steel fibers into traditional permeable concrete. Laboratory tests were conducted to backcalculate thermal conductivity of permeable concrete using the measured temperature files and thermal transfer models. The indoor experiments with controlled thermal radiation and water spray were conducted to measure surface temperatures of permeable concrete slabs in dry and wet conditions. Finite element models were developed to simulate thermal behavior of permeable concrete pavement and the simulation model results were found in good agreement with the indoor temperature measurements. The results showed that the permeable concrete slabs have the higher surface temperature than conventional concrete slab in dry conditions, but similar or lower surface temperatures in the wet condition, depending on water evaporation rate. The peak surface temperature of high-conductivity permeable concrete was 1–3 °C lower than that of conventional permeable concrete due to high thermal condition. The simulation results of outdoor environment show that permeable concrete pavement caused slightly greater heat output on sunny days but much smaller heat output on rainy days to the near-surface environment, as compared to conventional concrete pavement. The increase of thermal conductivity of permeable pavement can further reduce the heat output by 2.5–5.2%. The study findings prove that the high-conductivity permeable concrete is an effective method to alleviate UHI effect in dry and wet conditions.

Reinforced SCC one-way slabs: time-dependent flexural cracking control

Fibre-reinforced self-compacting concrete (FRSCC) is a high-performance building material that combines the positive aspects of the fresh properties of self-compacting concrete (SCC) with the improved characteristics of hardened concrete as a result of fibre addition. To produce SCC, either the constituent materials or the corresponding mix proportions may notably differ from conventional concrete (CC). Therefore, it is vital to investigate whether all the assumed hypotheses about CC are also valid for SCC structures. This paper reports a study in which eight SCC and FRSCC slabs of similar cross-section were monitored under service loads for up to 240 d. The recorded time-dependent cracking and deflections are presented. The steel strains within the high-moment regions, the concrete surface strains at the tensile steel level, deflection at the mid-span, crack widths and crack spacing were recorded throughout the testing period. The experimental results show that the instantaneous crack widths and spacings for the normal SCC slab series were close to and much less than, respectively, the corresponding variables for the normal CC slab series.

A study of steel wire mesh reinforced high performance geopolymer concrete slabs under blast loading

In this study, a novel green construction material, high performance alkali-activated geopolymer concrete is introduced. Both numerically and experimentally investigations were conducted on a new type of structural slabs made of steel wire mesh reinforced geopolymer concrete against close-in ground surface explosion. Steel rebar reinforced conventional concrete slabs are also studied to compare the results. The experimental investigation was conducted to study the slab damage mechanism. It is found that the steel wire mesh reinforced geopolymer concrete slab showed less damage and fragmentation under 50 kg Trinitrotoluene (TNT) blast load within 3 m, 5 m and 7 m distances as compared to the C30 concrete slab. Numerical analysis was then conducted to further investigate the slab dynamic responses. Combining the steel wire mesh reinforcement with geopolymer concrete can help increase the blast resistance capacity leading to promising and environmental friendly structural protective design.
