Spectral analysis of cross-hole sonic logging data for pile integrity assessment

Ensuring the safety of foundations requires advanced non-destructive testing techniques. Cross-hole sonic logging (CSL) is a widely adopted method for evaluating the integrity of deep foundation elements, such as bored piles, barrettes, and diaphragm walls. This method involves analyzing the propagation time and relative energy of ultrasonic pulses transmitted and registered by probes inserted into pre-installed access tubes. However, in certain cases, standard analyses may not effectively distinguish anomalous signals arising from defects and other factors unrelated to concrete quality. Our study explores the potential of an alternative frequency-domain approach for CSL data analysis. We propose new attributes to quantify ultrasonic signal spectra, including spectrum area, normalized spectrum area, weighted mean frequency, and maximum frequency. These attributes are automatically calculated, eliminating the need for additional data processing time and minimizing the risk of human error. The proposed approach was applied to CSL data collected from two bored piles of 46 m length and successfully identified signals classified as anomalous through standard time-domain analysis. Further research is deemed necessary to fully explore the potential of the frequency-domain approach in enhancing the information content and reliability of CSL pile integrity testing

Comparative study of the use of Ordinary Portland Cement (OPC), Portland Composite Cement (PCC) and Hydraulic Cement (HC) types in high quality concrete with an independent compaction system

One of the problems faced in the manufacture of high-strength concrete is the difficult workability, and the rising price of OPC and PCC cement. To overcome these problems, a self-compacting system is needed in concrete to make the workability easier to work with and the use of other types of cement besides OPC and PCC, such as the latest product HC, to reduce the cost of making high-strength concrete. The objective of this study was to compare the use of OPC, PCC and HC cement types in high strength concrete with self-compacting system, so as to overcome the high-quality problem more effectively. The manufacture and testing of test specimens were carried out at the PT Pionir Beton Industri Laboratory with the results of testing the compressive strength of OPC type cement at 955.93 kg/cm2, the compressive strength of PCC cement concrete at 866.22 kg/cm2, and the compressive strength of HC cement concrete at 885.83 kg/cm2. It can be concluded that the use of OPC cement in concrete mixes will produce the strongest concrete among the other two types of cement.

Experimental study on the utilization of construction and demolition waste of recycled aggregate with GGBS and I-Crete in pavement quality concrete

This study investigates the mechanical properties of M40 concrete in Pavement Quality Concrete (PQC) by incorporating Recycled Aggregates (RA) from construction, demolition waste and industrial wastes, such as GGBS and I-Crete, for sustainable pavement construction. The research explores varying proportions of RA (25% to 100% by weight in 25% intervals). Results show concrete mechanical strength decreases with higher RA proportions but all mixes still meet target strength criteria (compressive, flexural, split tensile) at 7, 28, and 90 days of curing. Further testing on 100% RA (MRCA-100) with GGBS admixture from 5% to 35% in 5% increments found strength improves significantly up to 10% GGBS replacement by cement weight, with subsequent decreases at higher percentages Initially. Then introducing the mineral additive, I-Crete at 2% by weight of cement in 15% to 35% GGBS range results in notable strength enhancement, peaking at 25% GGBS replacement. Ultrasonic pulse velocity (UPV) and water absorption tests showed similar trends in 28-day strength across all mixes. Increased strength from better bonding was observed, with Scanning Electron Microscopy (SEM) showing enhanced hydration and bonding due to mineral admixture and additive. These findings underscore the efficacy of such additives in enhancing the mechanical strength of sustainable PQC.

Assessment on Quality of Coarse and Fine Aggregate of Riverbed Quarry as Construction Material Used in Kaski District of Nepal

Quality of the composite material and ingredient of the materials in composite material plays a vital role in the sustainable infrastructure development. The quality of concrete is conformance to technical requirements as per specification or fitness for uses having minimum acceptance level to use the products. Among the various properties of fine and coarse aggregate of sampled quarry, only physical and mechanical properties of coarse and fine aggregates were tested in the laboratory, analyzed and compared with IS code and Standard Specification for Road and Bridges Works-2073 (with second amendment-2078) of Department of Roads (DoR), Nepal. Results revealed that physical properties of all the sampled quarry on gradation of coarse and fine aggregate lies within the IS code provision, whereas only source of Rato Pairo Mishi Tunda Shanik Ghat and Gahara Ghat comply the specifications defined by Standard Specification for Road and Bridge Works -2073 (with second amendment-2078), The specific gravity and water absorption of all the sampled quarry satisfied as per the Standard Specifications for Road and Bridge Works-2073 (with second amendment-2078). The mechanical properties such as crushing value of coarse aggregate of all sampled quarry satisfied standard value, impact value of sampled aggregate from Babya Tara, Mahari Ghat and Chuina Pahara Ghat dosen't comply within standard value, and abrasion value of sampled aggregate from Mahari Ghat and Chuina Pahara Pasupati Ghumari Ghat does not meet the standards as defined by the Standard Specifications for Road and Bridge Works-2073 (with second amendment-2078). The properties of fine and coarse aggregate have significant influence on performance, quality and serviceability of concrete mix & finally influence durability of the engineering structures.

Evaluation of Compressive Strength of UHPC Cured in A Winter Low-temperature

Deteriorating concrete quality is a typical problem reported in a low-temperature environment in winter. Therefore, efforts to evaluate and secure the quality of concrete are always carried out. In this study, the researchers primarily focused on developing curing methods and improving the quality of mixing materials, including chemical admixture, to secure compressive strength of concrete. The study investigated the compressive strength of concrete according to its age and observed that the compressive strength increases under the experimental conditions without any additional protection measures for the winter season. The compressive strength of the cured concrete was measured at 0 and -15 ℃ for 100 MPa Ultra-high-performance concrete (UHPC). Additionally, the property of compressive strength was compared with that of UHPC, which suffered damage due to the cold, went through a certain recovery period at room temperature. Consequently, it was confirmed that UHPC, damaged from the cold weather, achieved the specific compressive strength after 84 days. The findings from this study can enhance further understanding of the characteristics of UHPC in winter environments and contribute to establishing a construction plan for withstanding the winter seasons.

Utilization of Plant Waste Materials as a Partial Replacement of Cement and Fine Aggregates in Concrete Production

The research focused on possibility of producing high quality concrete by the way of adding plant waste materials like sugarcane bagasse ash (SBA), rice husk (RH) and cassava starch (CS) to concrete mixtures. Varying percentages of SBA (0, 5, 10, 15% - weight of the cement), rice husk (0, 5, 10, 15% - weight of the fine aggregates) and cassava starch (0, 1, 2, 3% - weight of the cement) were incorporated into the concrete mixtures design. Comprehensive laboratory investigations were done on the concrete’s workability (slump), density and mechanical strength, to establish the impact of these organic materials on the mechanical parameters of the concrete produced. The laboratory test results show that SBA and CS augmented the concrete slump rate whereas, the rice husk retarded the concrete’s workability. The result of the density indicated that the rice husk and SBA reduced the concrete’s density; however, the cassava starch caused substantial increment in the concrete’s density. On the concrete mechanical properties, it was noted from the results that the compressive strength was boosted by the incorporation of SBA and CS. The maximum compressive strength (23.7 N mm-2) was recorded through by substituting the cement with 10 and 2% of SBA and cassava starch respectively, in the presence of 10% RH as partial replacement of the sand. This study findings had revealed the potential of SBA, rice husk and cassava starch combinations in the right mixture design, to produce light-weight concrete material having sustainable high compressive strength.

IMPACT EFFECT ON THE EXISTING AND STRENGTHENED REINFORCED CONCRETE COLUMNS

Reinforced concrete (RC) columns are the main vertical elements in the buildings. Superstructure loads are transferred to the foundation by the columns whose design involves sufficient section sizes with longitudinal and transverse reinforcements. However, RC columns are required to be strengthened when low concrete quality and lack of reinforcement is stated. The most common strengthening technique for the RC columns is jacketing. In this method, strength of the existing column is improved by concreting and installing jacketing reinforcements. Although columns are designed according to several vertical and lateral load combinations, impact loads whose effects may reach very high values at short notice are not regarded. In the scope of this study, impact behavior of the existing and strengthened RC columns is numerically investigated. For this purpose, non-linear incremental dynamic analysis is carried out by Abaqus software that is widely utilized by engineers for such solutions. Acceleration, displacement and impact load values as well as crack patterns are obtained after numerical analysis. The results are comparatively presented for the existing and the strengthened columns. Analysis outputs reveal that proposed finite element models give an opinion about the impact responses of the RC columns. Consequently, it is evaluated that this study may make contribution to the researchers generating non-linear analysis without having to perform impact experiments that require high costs and heavy workloads in the laboratory conditions.

A Review of Cross-Hole Ultrasonic Logging for Foundation Integrity Testing and its Evaluation Criteria

Since the concrete quality of cast in-situ foundation is crucial, the cross-hole ultrasonic logging (CSL) method has become an effective method to assess the homogeneity and integrity of concrete without being limited by the pile length or soil type. Although the testing procedure for CSL is well defined by test standards including ASTM, the interpretation and evaluation criteria of CSL testing results, in contrast, are not well defined and controlled by uniform standards. The current state of practice recorded the application of different rating criteria with different parameters applied for foundations acceptance evaluation. A task force formed by Deep Foundations Institute (DFI) in 2019 has proposed improved rating criteria for CSL results evaluation with the vision of standardized and uniform evaluation criteria in the future. This paper summarizes the current practice of the CSL method and compares the commonly used rating criteria with the currently proposed improved criteria.

Bio-based admixtures (BBAs) are emerging as a promising class of additives for concrete, of- fering a more sustainable and environmentally friendly alternative to conventional chemical admixtures. Derived from various natural or biological sources, including plants, animals, and microorganisms, BBAs have shown potential in enhancing the performance characteristics of concrete in several key areas. This review article provides an in-depth exploration of BBAs, be- ginning with a detailed classification of the different types of BBAs based on their source mate- rial and production methods. It then delves into the various characterization techniques used to assess the properties and performance of BBAs, providing insights into their impact on the workability, strength, durability, and rheology of concrete. The article also discusses the diverse application areas of BBAs, highlighting their versatility and potential for wide-ranging use in the construction industry. It further identifies and discusses the challenges associated with the use of BBAs, such as issues related to compatibility with different types of cement and concrete, storage and shelf-life considerations, quality control and standardization concerns, and cost-effective- ness. In conclusion, the review emphasizes that while BBAs hold great promise as an alternative to conventional chemical admixtures for concrete, there is a need for more interdisciplinary collaboration and research to overcome the identified challenges and fully realize their poten- tial. The paper calls for further studies focusing on optimizing the production and application processes of BBAs, as well as developing standardized testing and quality control procedures.

Hyper-tuning gene expression programming to develop interpretable prediction models for the strength of corncob ash-modified geopolymer concrete

Geopolymer concrete has been offered as an alternative to traditional concrete due to the environmental consequences of cement manufacture. It is also unable to make adjustments if the concrete's strength after casting does not meet the required strength. Because of this, it is highly beneficial to make strength predictions before pouring concrete. This study proposes applying the gene expression programming (GEP) method to forecast the mechanical strength of slag and corncob ash-based geopolymer concrete (SCA-GPC). The SHapley Additive exPlanations (SHAP) approach was used to identify the significance of parameters used for modeling. Best-fitted simulations and exceptional prediction performance were produced by the GEP (R2 = 0.96, MAE = 1.876 MPa, MAPE = 6.00%, RMSE = 2.417 MPa, and NSE = 0.954), (R2 = 0.94, MAE = 0.178 MPa, MAPE = 3.50%, RMSE = 0.236 MPa, and NSE = 0.942), and (R2 = 0.94, MAE = 0.126 MPa, MAPE = 3.60%, RMSE = 0.154 MPa, and NSE = 0.935) for compressive, flexural, and split tensile strengths models of SCA-GPC, respectively. Error and efficiency-based statistical checks confirmed the accuracy of the created models. The SHAP research also found that the mechanical strength of SCA-GPC was mostly controlled by slag quantity, curing age, water quantity, and fine aggregate quantity in the mix proportion. This research showed that the mechanical strength of SCA-GPC could be effectively predicted using the GEP method. The implementation of such methods will significantly improve the process of ensuring the quality of geopolymer concrete.

Behaviour of Paver Block by Addition of Waste Rubber

Concrete is one of the widely used construction material in the construction industry. The durability and aesthetics aspects of concrete made it to use in making paver blocks which are used in outdoor versatility application as street road, sidewalks, and other Construction places. Paver block has low cost maintenance and easily replace with a newer one at the time of breakage. The quality of concrete used to make paver block may be the major issue, so that the durability of paver block depends on quality of concrete. Rubber is used in different fields throughout the world. But the utilization or disposal of waste rubber after its regular. Thus an attempt is made by inclusion waste rubber into the concrete and to measure how rubber affects the properties of paver block. This research study presents the information about the development of the rubber mould paver block with inclusion waste rubber.

A Study on Sustainable Concrete by using Recycled Concrete Aggregate and Waste Glass

Sustainable and affordable building materials are a developing concern in the construction sector. This abstract outline a creative method for creating a cost-effective concrete mix that uses discarded glass as the fine aggregate and recycled coarse aggregate (RCA) as the main coarse material. The goal is to investigate whether using recycled materials instead of traditional aggregates is feasible while both addressing environmental issues and lowering construction costs. The proposed concrete mix's mechanical qualities, financial ramifications, and environmental impact were all compared through laboratory experiments, a thorough assessment of the literature, and comparative analysis. The scrap glass came from glass bottles and other abandoned containers, while the RCA came from crushed concrete waste. The experimental studies assessed different concrete mix proportions while taking into account various replacement amounts for RCA and waste glass. Along with other crucial qualities like workability, density, and durability, the mechanical properties including compressive strength, tensile strength, and flexural strength were evaluated. The test outcomes were contrasted with a control concrete mixture made up only of common aggregates. The results of the research show that using waste glass as fine aggregate and recycled coarse material in the making of concrete can substantially reduce building costs. The mechanical performance of the concrete was not significantly affected by the use of the RCA and waste glass in place of normal aggregates. Additionally, using these recycled materials lowers the amount of waste that is transported to landfills and helps conserve natural resources. Economic concrete mixtures that use waste glass as fine aggregate and recycled coarse material have enormous potential for green building techniques. This method is appealing for large-scale construction projects due to the lower material cost and positive environmental effects. To make sure the best mix proportions are employed, it is necessary to take the specific application into account as well as the engineering requirements. This study supports continuing initiatives to advance affordability and sustainability in the building sector. As well as studying further strategies to improve the engineering features of recycled aggregate-based concrete, future research could concentrate on examining the long-term performance and durability of the suggested concrete mix.

Variation of dynamic elasticity modulus with experimentally determined concrete compressive strength

In reinforced concrete structures, one of the most important factors for structural safety is the quality of concrete. The first thing that comes to mind for concrete quality is the compressive strength of concrete. However, properties such as elasticity modulus are also among the properties that determine concrete quality. Since concrete is a brittle material, different methods are used to determine dynamic elasticity modulus. In practice, dynamic elasticity modulus of concrete can be identified by utilizing concrete compressive strength value. In this context; compressive strength tests were performed on a series of concretes accordingly relevant standards. Since it is difficult to determine elasticity modulus from the stress and strain relationship, the dynamic elasticity modulus values in this study was calculated using empirical formulas according to TS 500-2000, ACI 318-95 and CEB-FIP 1978 on the basis of experimental data in this study. The relationship between the calculated dynamic elasticity modulus values and concrete compressive strength was analyzed. From the study, it is concluded that as concrete compressive strength increases, dynamic elasticity modulus increases for the concrete specimens.

Alternative salt frost scaling test procedure for exposure class XF2

Concrete structures in cold and moderate climates are often exposed to a combined salt frost attack, which can cause scaling damage. Consequently, numerous test procedures were developed to determine the resistance of concrete compositions against this kind of attack. These tests mimic a severe attack with high levels of saturation, which is typical for horizontal concrete elements or structures, such as concrete pavements. Very few approaches exist for testing the salt frost scaling resistance of concretes for vertical concrete elements like bridge columns, which are subjected to only moderate levels of saturation during salt frost attack (exposure class XF2). As such elements usually didn’t show notable scaling damage in practice, this hasn’t posed a problem until recently. However, the increasing use of low carbon cements with high clinker substitution rates might increase the vulnerability against salt frost exposure for such concrete elements to some extent. To ensure adequate durability it is desirable to determine the performance of the concrete in an actual test procedure instead of relying on descriptive criteria alone. Thus, a less severe test method was developed, which is based on the CDF test. It was shown that the modified test procedure can distinguish correctly between different concrete qualities. Furthermore, the applicability of an acceptance criterion for the method was investigated.

Developing a sustainable self-compacting geopolymer concrete with 100% geopolymer-coated recycled concrete aggregate replacement

PurposeConcrete, the second most used material in the world, surpassed only by water, relies on a vast amount of cement. The process of cement production emits substantial amounts of carbon dioxide (CO2). Consequently, it is crucial to search for cement alternatives. Geopolymer concrete (GC) uses industrial by-product material instead of traditional cement, which not only reduces CO2 emissions but also enhances concrete durability. On the other hand, the disposal of concrete waste in the landfills represents a significant environmental challenge, emphasising the urgent need for sustainable solutions. This study aimed to investigate waste concrete's best form and rate as the alternative aggregates in self-compacting and ambient-cured GC to preserve natural resources, reduce construction and demolition waste and decrease pertinent CO2 emissions. The binding material employed in this research encompasses fly ash, slag, micro fly ash and anhydrous sodium metasilicate as an alkali activator. It also introduces the best treatment method to improve the recycled concrete aggregate (RCA) quality.Design/methodology/approachA total of25%, 50% and 100% of coarse aggregates are replaced with RCAs to cast self-compacting geopolymer concrete (SCGC) and assess the impact of RCA on the fresh, hardened and water absorption properties of the ambient-cured GC. Geopolymer slurry was used for coating RCAs and the authors examined the effect of one-day and seven-day cured coated RCA. The mechanical properties (compressive strength, splitting tensile strength and modulus of elasticity), rheological properties (slump flow, T500 and J-ring) and total water absorption of RCA-based SCGC were studied. The microstructural and chemical compositions of the concrete mixes were studied by the methods of energy dispersive X-Ray and scanning electron microscopy.FindingsIt is evident from the test observations that 100% replacement of natural aggregate with coated RCA using geopolymer slurry containing fly ash, slag, micro fly ash and anhydrous sodium metasilicate cured for one day before mixing enhances the concrete's quality and complies with the flowability requirements. Assessment is based on the fresh and hardened properties of the SCGC with various RCA contents and coating periods. The fresh properties of the mix with a seven-day curing time for coated RCA did not meet the requirements for self-compacting concrete, while this mix demonstrated better compressive strength (31.61 MPa) and modulus of elasticity (15.39 GPa) compared to 29.36 MPa and 9.8 GPa, respectively, for the mix with one-day cured coated RCA. However, incorporating one-day-cured coated RCA in SCGC demonstrated better splitting tensile strength (2.32 MPa) and water absorption (15.16%).Research limitations/implicationsA potential limitation of this study on SCGC with coated RCAs is the focus on the short-term behaviour of this concrete. This limited time frame may not meet the long-term requirements for ensuring the sustained durability of the structures throughout their service life.Originality/valueThis paper highlights the treatment technique of coating RCA with geopolymer slurry for casting SCGC.

Image‐based analysis of fresh concrete flow ‐ determining the correlation between flow behavior and rheological properties

AbstractBesides compressive strength, the workability of fresh concrete is one of the most important characteristics of concrete. Only by adapting the rheology of the fresh concrete to the geometry of the element to be casted, the formation of air voids and damages can be avoided. This holds even more so true for 3D printable concrete. Currently, empirical test methods such as the slump test are used to determine rheological parameters. Rheometer tests, on the other hand, allow a much deeper insight into the rheological properties of concrete but are more challenging. Further, all currently available test methods can only be applied on a batch basis.In the paper at hand, a new approach for an automatic digital concrete quality control is presented using modern computer‐vision based analysis methods. Using a newly developed experimental setup, the flow of mortar down an inclined open channel is studied using a monocular camera setup. Differences in the mortar's rheology result in different flow behaviors which can be optically detected. Utilizing dense optical flow, rheological parameters are determined from the acquired monocular image sequences. The results shown in this paper prove that the computed flow behavior of the investigated mortars precisely correlates with their rheological properties, demonstrating the high potential of the method for an automated in‐line testing of fresh concrete e.g. during the discharge of a mixing truck.

Experimental Study on the Mutual Influence of Fly Ash, Silica Fume & Fibers on Strength Enhancement of Portland Cement

Abstract: Mineral additives have a wide range of applications today because of their benefits such as waste evaluation for ecological balance and improving the physical and mechanical qualities of cement or concrete. Fly ash and silica fume are two of the wastes. These raw materials were subjected to physical, chemical, mineralogical, and molecular analysis for this purpose. Engineered cementitious composites (ECC) with excellent tensile strain capacity and repeated cracking often contain fly ash (FA) as a key component. Silica fume can either be "added" (added individually at the concrete mixer) or mixed with a composite cement that is manufactured in a factory. This essay examines the advantages and usefulness of using fly ash and silica fume. Silica fume can typically be used with chemical admixtures, and it is typically used with a super-plasticizer, just like with conventional concretes. Tests should be conducted to determine the right dose levels as the performance of admixtures may depend on the unique characteristics of the source of the cementation's material (as with OPC cement). Supplementary cementing materials (SCMs) are utilized in concrete to partially replace the Portland cement component and exhibit pozzolanic and/or cementitious qualities. High-performance concrete contains an essential component called supplemental cementing material. In particular, when great strength and durability turn out to be the most desired attributes of high-performance concrete, the insertion of supplemental cementing material is crucial. Several well-known supplemental cementing materials, including fly ash, silica fume, and powdered granulated blast-furnace slag, are presented in this work. The impact of using steel fibers, fly ash, silica fume, and various combinations of them are evaluated in this paper. This study aims to ascertain how fly ash, silica fume, and fibers interact with Portland cement to increase concrete strength, reduce internal cracks, and increase tensile strength.

Currently in Indonesia a lot of construction work and concrete is one that is widely used. In the development of concrete construction technology, especially in Indonesia, it is necessary to have concrete capable of carrying high loads using available materials. The development of high quality concrete has 3 levels, namely High Strength Concrete (HSC), High Performance Concrete (HPC) and Ultra High Performance Concrete (UHPC). Against the background of future needs, in this study experiments were carried out in a concrete laboratory to obtain high performance concrete mixes with local materials. At the experimental stage, testing of tools and materials, concrete mix, casting, slump test, manufacture of specimens, maintenance, checking of unit weight, compressive strength test, split tensile strength and modulus of elasticity was carried out. In that study there were 11 variations. Furthermore, the test results were analyzed by the data to draw conclusions. The results showed that the average compressive strength of concrete at 3 days of age was relatively high, namely 53.8 MPa which could be used for fast precision work. In variation 11 mixture (PCC Cement, Silica Fume, Sand Mesh 35-60, Silica Mesh 325, Water, Viscocrete Superplasticizer 8670 MN, Fly Ash 7% and Polypropylene Fiber 0.2%) tested for 28 days, the compressive strength reached 87.5 MPa, so it can be said as HPC concrete. In this study it was concluded that the use of local materials, Sinabung Volcanic Ash waste and fly ash can improve the quality of concrete and can also reduce environmental pollution.
