Summary: This study investigates the performance of foam concrete containing palm oil fuel ash (POFA) as a sand replacement. The results show that with an increase in the POFA content, the mechanical properties and microstructure of the foam concrete significantly improved. Additionally, the capillary sorption and gas permeability were enhanced, and optimum water absorption ability and thermal conductivity were obtained using 30% POFA. However, an increase in the POFA content led to higher expansion, strength loss, and microstructure deterioration when the foam concrete was exposed to sulphate attack.

Summary: The disposal of agricultural waste ashes has caused severe pollution worldwide due to the rapid implementation of biomass-based power plants. However, these ashes can be effectively used as an alternative material to conventional cement. A comprehensive review on the performance of two widely available agricultural waste ashes, palm oil fuel ash and rice husk ash, in concrete is attempted. The physical, chemical, microstructural, and pozzolanic characteristics of the ashes are systematically reviewed. The optimal replacement level for both ashes in concrete is recommended. Superior performance in terms of workability and resistance against chloride ion penetration, acid, and sulphate attack is observed for the palm oil fuel ash and rice husk ash blended concretes compared to conventional concrete.

Summary: The study found that replacing 20% of cement with POFA can produce slightly better performance than other mixes, and a density reduction of 43% can be achieved with 30% POFA replacement. However, a decrease in compressive strength was observed when POFA replacement exceeded 20%, which may be attributed to the high LOI content and porous nature of POFA.

Summary: Cement production leads to high energy consumption and the generation of harmful gases. This study investigates the use of palm oil clinker and ultrafine palm oil fuel ash as alternative materials in concrete production. The study utilizes the response surface method to optimize the density and water absorption properties of concrete. The results show a decrease in density and an increase in water absorption when using palm oil clinker as a replacement for coarse aggregate, and a decrease in water absorption when using ultrafine palm oil fuel ash as a partial cement replacement. The study recommends further use of ultrafine palm oil fuel ash due to its high pozzolanic property.

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.

This study investigated the thermal behavior of low-temperature PCM when subjected to varying temperature change rates and pore confinement inside the porous network of lightweight aggregates. The results showed that ramp rates affect the nucleation and crystallization growth process during the phase transition, and the pore structure of the aggregates affects the supercooling phenomenon and confinement pressure of the PCM.

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. Specimens with higher concentration of fractured aggregates achieve longer fatigue lives.

Summary: The susceptibility of building stones to fire and high temperature was investigated in this study by examining their physical and mechanical properties. 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.

Summary: This paper investigates the correlation between the friction coefficient and the surface roughness of concrete-to-concrete interfaces. Experimental tests were performed on specimens with different surface treatments, and the surface roughness parameters were analyzed and correlated with the shear strength and friction coefficient. The results showed that certain roughness parameters had a strong positive correlation with the friction coefficient, while others had little or no correlation. A novel combined roughness parameter with optimized correlation was proposed.
