This article presents a comprehensive review on the use of recycled concrete aggregate (RCA) and (RAC) in construction, with emphasis structural applications identification challenges opportunities RCA/RAC materials Southeast Asia. For first time as step towards potential standardization Asia, critically examines physical mechanical performance RCA RAC applications. Global demand is projected to surpass 50 billion tons by 2025, major Asian countries accounting for 62% consumption. At same time, global annual production construction demolition waste (C&DW) exceeds 3.57 tons, Asia responsible 53% this total. Recycling C&DW plays crucial role addressing environmental issues promoting sustainable practices. Previous research indicates that exhibits certain deficiencies, strengths 10% 20% lower than natural (NAC). level, elements show reductions up 15% axial, bonding, shear, flexural relative NAC. Measures such treatment RCA, recycling process optimization, optimized mixing techniques are recommended enhance properties. Prioritizing during exploring novel strengthening could elevate improve make it suitable The also found efforts vary significantly across (particularly Asia), some lagging regarding technologies best Various strategies proposed discussed. main findings shortcomings previous investigations discussed, further needs identified.

Cold weather conditions pose significant challenges to the performance and durability of concrete materials, construction processes, structures. This paper aims provide a comprehensive overview material-related in cold construction, including slow setting, reduced curing rate, slower strength development, as well frost damage, early freezing, freeze–thaw actions. Various innovative materials technologies may be implemented address these challenges, such optimizing mix proportions, chemical admixtures, supplementary cementitious advanced techniques. The also examines impact weather-related for personnel, equipment, machinery environments highlights importance effective planning, communication, management strategies. Results indicate that successful implementation appropriate strategies can mitigate reduce time, enhance performance, durability, sustainability structures freezing temperatures. emphasizes staying updated about latest advancements best practices field. Future trends include development smart functional manufacturing techniques, integrated design, optimization tools, all with strong focus on resilience.

Waste-based concrete stands as an environmentally friendly and sustainable option compared to conventional concrete. The waste-based holds the potential lessen unfavorable ecological effects associated with construction. In this research, along ground granulated blast furnace slag (GGBS) fly ash (FA) alternative binders cement, lead smelter (LSS) sand recycled coarse aggregate (RCA) have been utilized in production of influence reduced graphene oxide (rGO) on mechanical durability characteristics has assessed. Four rGO dosages 0%, 0.05%, 0.1% 0.3% by weight binder were incorporated. Scanning electron microscopy thermogravimetric analysis conducted assess rGO-reinforced concrete's microstructure. findings indicate that improved is optimum dosage increase compressive strength (47%), splitting tensile (44%), flexural (42%) decrease water absorption (45%) drying shrinkage (35%) Further leads properties addition, incorporating 20% FA, 50% GGBS, 100% LSS, RCA reinforced exhibits similar enhanced performance can be related porosity, refined pore structure, densified hydration products increased degree rGO.
