Summary: This paper investigates the preparation of a high friction surface treatment (HFST) using magnetite (MT) aggregates instead of conventional calcined bauxite (CB) aggregates as microwave absorbers. The deicing properties by microwave heating and long-term skid resistance of HFST with different proportions of CB and MT aggregate were evaluated. The results showed that the electromagnetic characteristics of HFST were greatly enhanced by the addition of MT, leading to higher microwave heating and deicing efficiency. However, the long-term skid resistance of HFST was reduced by the addition of MT.

Summary: The influence of waste glass aggregate (WGA) with fly ash in certain proportions on geopolymer concrete (GPC) was studied by varying the molarity and WGA proportion. Tests on workability, setting time, compression strength (CS), splitting tensile (ST), and flexural strength (FS) were performed, and the results showed that slump values increased with higher molarity and lower WG percentages. CS, ST, and FS tended to decrease with increasing proportion, but increased with higher NaOH molarity. An equation was derived to predict the compressive strength of the geopolymer mixture used in this study.

Summary: Large amounts of waste glass generated globally contribute to environmental pollution and strain landfill capacities. This study investigates the use of waste borosilicate glass (BSG) as a replacement for aggregate particles in asphalt pavements. Various structural, functional, and durability parameters of the asphalt containing BSG were evaluated. The results showed that increasing BSG content reduces the required binder content, and 10% dosage of BSG provides maximum stability, dynamic modulus, and rut resistance. However, the addition of BSG negatively affects the fatigue resistance of the asphalt, particularly at higher dosages. Moreover, BSG has less affinity to adhere to bitumen, especially at dosages greater than 10%. On the other hand, skid resistance improves with increasing BSG content.

Summary: In order to improve the adhesive strength and noise reduction properties of micro-surfacing, waste rubber powder was added to the mixture. The addition of 2% of 40-mesh rubber powder and 8% asphalt-aggregate ratio resulted in the densest structure of the slurry and significantly improved high-temperature performance and aging resistance, while reducing noise generation and transmission. However, there was no significant improvement in water stability performance. The waste rubber powder enhances the strength of the micro-surfacing by interweaving with cement hydration products and asphalt mortar, and has an excellent noise reduction effect.

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.
