Summary: The study demonstrated that the addition of nano-CaCO3 in sulphoaluminate cement-based reactive powder concrete (RPC) can shorten setting time, improve strength, and enhance hydration properties. The results also showed an increase in heat flow rate and cumulative heat of hydration with higher nano-CaCO3 content. Additionally, the XRD, TG, ICP, and isothermal calorimetry results indicated that nano-CaCO3 promotes the hydration process of RPC by forming more hydration products and compacting the microstructure.

Summary: In this study, the possibility of introducing recycled concrete powder (RCP) into concrete as a substitute for cement was explored. Nano-silica (NS) was used to optimize the hydration and mechanical properties of the cement-based materials. The results showed that adding NS into RCP-cement pastes reduced the setting time of cement pastes and increased the early hydration rate and hydration heat. However, the mechanical strength of the mortar decreased as RCP replaced part of the cement. Nonetheless, 2% NS was able to compensate for the strength loss caused by RCP. X-ray CT and MIP results revealed that RCP increased the pore volume fraction and porosity of the mortar, while NS decreased the number of pores and refined the pore size. XRD and SEM analysis further confirmed that the presence of NS eliminated the adverse effects brought by RCP.

Summary: Regenerated nano-FeB was prepared from construction waste iron powder, and composite cement paste blocks were prepared. Mechanical and electrical conductivity tests were conducted on the composite cement paste, and the results showed that the optimal performance improvement was achieved when the content of regenerated nano-FeB was 0.075%. At 28 days, the compressive strength of the composite cement paste increased by 39.8% and the volume resistivity decreased by 24.8% compared to the control group. Scanning electron microscope (SEM) and Raman spectroscopy were used to reveal the regulation mechanism of regenerated nano-FeB on cement paste, demonstrating its ability to enhance the internal microstructure and properties of cement paste.

Summary: The study investigates the sulfate and chloride resistance of cement composites manufactured using electrolyzed water, showing that the electrolyzed water-based specimens exhibit enhanced durability performance with reduced compressive strength losses and corrosion potential compared to control specimens. This improvement is attributed to the less porous and compact microstructure of the hardened composites, leading to lower ingress of deleterious agents.

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. 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.
