Summary: This study evaluates the performance of pervious concrete produced with construction and demolition waste (CDW) aggregates. Different replacement levels of natural aggregates (NA) by recycled concrete aggregate (RCA), the use of rheology modifying admixture, and reduction of water-cement ratio were investigated. The laboratory and field results showed that RCA replacement improved hydraulic properties but decreased mechanical behavior of pervious concrete.

Summary: This paper investigated the mechanical and permeability performances of pervious concrete mixtures produced using different aggregates and fibers. The results showed that the pervious concrete specimens exhibited adequate mechanical performance, particularly with the inclusion of polypropylene fibers and steel fibers, which significantly improved the permeability performance and abrasion resistance. Moreover, using smaller-sized and more uniform aggregates generally increased the overall performance of the pervious concrete specimens.

Summary: The aim of this study was to investigate the possibility of using recycled concrete waste as aggregate and car tire rubber granules as partial substitution of natural aggregate in the production of pervious concrete. The results showed that replacing 50% of the aggregate weight with recycled concrete aggregate improved the mechanical properties of pervious concrete. However, replacing 10% of the aggregate volume with rubber waste aggregate reduced the compressive strength by a maximum of 11.4%. The addition of polymer fibers enhanced the compressive and tensile strengths of the concrete.

Summary: This study investigates the impact of RCA quality grades and replacement rates on the mechanical property, permeability, sulfate resistance and abrasion resistance of IRPC. The experimental results show that IRPC has good resistance to sulfate attack, but sulfate attack and the addition of RCA will reduce the abrasion resistance of IRPC. However, when the replacement rate is lower than 50% and the RCA quality is better, the abrasion resistance of IRPC will be improved under sulfate attack.

Summary: Geopolymer concrete is an eco-friendly alternative to traditional concrete, as it is produced using waste materials instead of cement. The incorporation of treated recycled aggregates has a beneficial effect on the compressive strength of the concrete, but may also result in a slight increase in water absorption and peeling mass after freezing and thawing cycles.

Summary: The study investigated the physical and hydrological properties, compressive strength, and abrasion capacity of pervious concrete paving blocks with the use of recycled concrete aggregate (RCA) and sand. The results showed that replacing natural coarse aggregate with 15% RCA increased the compressive strength, and RCA levels up to 30% did not compromise the hydraulic and mechanical performance. However, incorporating sand decreased the porosity and infiltration capacity of pervious concrete while hindering the improvement of mechanical performance due to the lack of mixture homogeneity.

Summary: The research found that the combined application of lime and geogrid to clayey subgrade significantly enhanced its ductility and geotechnical characteristics, but excessive water pressure caused separation between geogrid layers and subgrade, leading to reduced uniformity and consistency. Moreover, controlling moisture to optimal levels can maximize the performance of subgrade, while excess moisture beyond optimal levels resulted in more voids, decreasing geotechnical properties.

Summary: This study explores the relationship between organisational culture and total quality management (TQM) implementation in the Australian construction industry. The findings suggest that Australian construction organisations are predominantly characterized by market and external focused cultures, while hierarchical cultures may hinder the successful implementation of TQM. On the other hand, a mix of cultures, specifically with adhocracy and market cultures dominating, may provide a favorable environment for the successful implementation of TQM.

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.
