Summary: Due to the increase of pollution, the disposal of waste materials like granite powder, iron powder, brick powder, and waste plastic particles has become a major environmental problem. Utilizing these industrial waste materials in the construction industry has many advantages. This study evaluated the addition of these waste materials as a fine aggregate in sustainable concrete production. The results showed that using iron powder as a partial replacement improved both static and dynamic properties of the concrete, while using waste plastic particles enhanced the impact energy at failure. The optimum value for granite powder and brick powder was found to be 10%.

Summary: The study demonstrates that the material excavated by tunnel boring machines can be used as structural concrete aggregate. The fresh concrete properties were within acceptable range, although porosity and chloride diffusivity were slightly higher. Aggregate processing method had minimal impact on concrete performance, and an increase in TBM aggregate content reduced porosity and permeability but decreased compressive strength. Thermal treatment of TBM aggregate can mitigate the loss in strength, and reliable isoresponse models were developed to predict concrete strength and durability.

Summary: The research indicates that the impact of rubber particles on the unstable fracture toughness is greater than that on the initial cracking toughness of RAC after exposure to high temperatures. However, the enhanced effect of rubber on the fracture resistance decreases after subjecting it to high-temperature treatment due to the softening and eventual decomposition of rubber. Therefore, a rubber content of more than 4% is not recommended to avoid drawbacks introduced by rubber, considering the mechanical and fracture performance of RRAC.

Summary: The use of scrap rubber in ballasted tracks has shown promising results in terms of vibration reduction, damping ratio enhancement, etc. However, its application in slab tracks has not been explored yet. This study investigates the use of ground and granulated rubber mixed with soil and treated with Polyurethane Foam Adhesive (PFA). The optimal content of rubber and PFA is determined through static direct simple shear test. Triaxial specimens prepared with the optimal rubber and PFA dosage are cyclically tested to assess the performance of the treated and untreated soil. A novel base layer for a slab track incorporating soil, scrap rubber, and PFA is proposed, showing improved settlement reduction, decreased excess pore water pressure, and enhanced damping ratio.

Summary: Oil palm shell concrete filled steel tube columns, which partially replaced conventional coarse aggregate with lightweight aggregate, demonstrated higher energy absorption and flexibility compared to normal weight concrete filled steel tube columns. The axial compressive behavior of OPS concrete filled CFT columns was studied for two grades of OPS concretes, showing comparable performance with normal concrete filled CFT columns but exhibiting a new post-peak behavior. The experimental results were compared with international standards EC4-1994 and ACI318-14, which provided reliable and conservative estimations of the axial load capacity of CFT columns.

Summary: High-strength, lightweight concrete is preferred for concrete structures due to its ability to limit size, but it is more brittle than normal-weight concrete. This study aimed to improve the ductility of high-strength, lightweight concrete by incorporating steel fibers. The results showed that the addition of steel fibers significantly increased the compression ductility, displacement ductility, and energy ductility of the concrete. The deformability and energy absorption capacity were also improved. Therefore, the use of palm oil clinker-based, high-strength, fibrous, lightweight concrete can enhance the ductility of structures under extreme loading conditions.

Summary: This study determined the optimum value of lightweight expanded clay aggregate (LECA) incorporation into roller compacted concrete pavement (RCCP) through response surface methodology (RSM). The results showed that incorporating LECA improved the workability of the concrete, decreased the density, and increased the water absorption. Increasing the LECA replacement in RCCP also resulted in lower thermal conductivity and heat capacity values.

Summary: The construction industry needs to consider both the mechanical and thermal performances of structural materials for energy-efficient buildings. There are conflicting properties between normal weight concrete (NWC) and lightweight aggregate concrete (LWAC). LWAC has high thermal efficiency but low mechanical strengths, while NWC has high mechanical strength but poor thermal efficiency. The inclusion of fibres in LWAC can improve its mechanical properties, but the thermal performance is not fully understood.

Summary: This study investigates the performance of reinforced concrete beams strengthened with Side Near Surface Mounted (S-NSM) technology through experimental, analytical, and finite element modeling methods. Five RC beams, including one control and four strengthened specimens, were tested under four-point bending loads to evaluate their flexural performance. The study examines the influence of different S-NSM reinforcement ratios on failure load, yield and ultimate strengths, deflection, strain, cracking behavior, and ductility of the beams. The results from experimental, numerical, and analytical analyses show good agreement, indicating significant improvements in yield and ultimate strengths as well as failure modes.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

Summary: Tailings dam break and leakage accidents pose a threat to the safety of people in mining areas and cause severe environmental pollution. This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.

Summary: This study investigates the fatigue behavior of concrete under different stress reversal conditions. The results indicate that stress reversal generally causes more severe damage and reduces the cycles to failure compared to tensile fatigue. Additionally, adding some level of compression contributes to the energy required for failure under stress reversal fatigue.

The results show that both compressive and tensile properties of stones are affected by temperature changes. The tensile strength is particularly sensitive to temperature changes, requiring special attention to the components subjected to tensile stress in stone buildings. Principal component analysis was used to predict the mechanical properties of stones, providing a new method for calculating the residual mechanical properties after high temperature or fire.
