Summary: The study discusses the effects of drying and wetting cycles on soil, particularly in relation to crack formation and tensile strength. Existing tensile strength models for unsaturated soils were found to have limitations, leading to the proposal of a new model that can be applied to both coarse-grained and fine-grained soils. The new model was shown to outperform existing models in terms of performance.

Summary: The study evaluated the use of cupola slag as a partial substitute for fine aggregates in concrete, finding that compressive strength increased with up to 30% replacement, followed by a decrease in strength with further addition of cupola slag. This increase was more pronounced at lower w/c ratios. Water penetration depth decreased with higher percentage of cupola replacement and abrasion resistance also improved. The study established correlations between strength and durability properties and conducted two-way analysis of variance to determine the impact of cupola slag replacement and w/c ratio on concrete properties.

Summary: In this study, a novel tensile strength framework is proposed to determine the tensile strength characteristic curve (TSCC) of both coarse- and fine-grained soils over the entire saturation range. The variation of the parameters for the TSCC model for different types of soils, testing methods, and sample preparation methodologies is critically assessed. The proposed framework is validated with experimental data sets for both coarse- and fine-grained soils, showing good agreement in most cases.

Summary: This study conducted fabric-to-fabric abrasion tests on soft silk fabrics in dry and wet states, at 500 and 1000 cycles, and evaluated the burst strength of the abraded samples. Abrasion resistance of soft silk was also evaluated using wool abradant to determine the standard abrasion cycle. Yarn samples were taken from the abraded areas of 25%, 50%, and 75% of the standard abrasion cycles of soft silk fabrics, and the tensile strength was evaluated at dry and wet conditions to understand the extent of damage caused by abrasion.

Summary: This study experimentally investigates crack formation and decompaction-wave propagation in a vibrated powder bed consisting of 5 μm glass beads. The vibrated powder bed demonstrates three distinct phases under different vibration conditions: consolidation, static fracture, and dynamic fracture. Notably, when the powder bed is strongly vibrated, an upward wave propagation is observed in the dynamic fracture regime. An interesting finding is that in fine cohesive powders, the decompaction-wave propagation speed, normalized to gravitational speed, is independent of the vibration strength. This suggests that the wave propagation speed is influenced by the balance between gravity and cohesion effect rather than vibration strength. The universality of the wave propagation phenomenon in coarser and low-density granular powders is also explored.

Summary: This paper investigated the splitting tensile and axial tensile behaviors of steel fiber recycled fine aggregate concrete (SFRFAC). The effects of RFA replacement ratio, steel fiber volume fraction, steel fiber type and silica fume content on the tensile properties of SFRFAC were studied. The results showed that RFA decreased the splitting tensile strength, axial tensile strength, and axial tensile elastic modulus of SFRFAC, while the addition of steel fiber and silica fume enhanced these properties. The relationship between splitting tensile strength and axial tensile strength, as well as the axial tensile stress-strain relationship of SFRFAC, were proposed.

Summary: This study evaluated the effects of Reclaimed Asphalt Pavement (RAP) incorporation in Emulsion-Treated Base (ETB) at different dosages, and compared RAP mixing and blending methods. The results showed that adding 50% RAP to ETB decreased the Maximum Dry Density (MDD) by 4.4% in RAP mixing, and only by 1.3% in RAP blending. ETB prepared with up to 75% RAP using the blending method met the minimum tensile strength requirement, and exhibited good rutting resistance and tensile strength. The study concluded that blending 50% RAP in ETB yielded the best performance in terms of strength, moisture resistance, and resistance to permanent deformation.

Summary: The study found that the addition of 50% RAP aggregates significantly reduced the strength and durability of RCCP mixes, while SCMs had a negligible effect on fresh properties but a significant impact on mechanical properties. It is not recommended to use SCMs for strength enhancement, but their use can greatly improve the abrasion resistance and durability of the mixtures.

Summary: In recent years, reclaimed asphalt pavement (RAP) has gained popularity among researchers for its low-impact development abilities and socioeconomic factors. This study investigated the possibilities of increasing RAP integration for foam-mix asphalt synthesis with alternative mineral fillers - fly ash and sugarcane ash. The study evaluated the influence of RAP and other fillers on the structural and functional properties of foam-mix asphalt and assessed CO2 emissions. The results showed that the addition of sugarcane ash and fly ash improved the indirect tensile strength of the foam mixtures.

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.
