The purpose of this comparison is to identify environmental impact hotspots within the life cycle of road pavement – covering extraction of natural resources, transportation, production, and finally pavement construction – and measure the opportunity The present study focused on environmental impact assessment (EIA) due to aggregate quarrying and crushing activities at four selected mining/crusher clusters in the middle catchment of Dwarka river basin of Eastern India. The requirement for "natural aggregate" is decreased by using this recycling The impact of MPs-microalgae aggregates on a broader-region environment warrants further investigation, particularly from the ‘One Health’ perspective integrating human, animal, and environmental health (Fig. In the present study, the aggregates are divided into three scenarios, depending on the production methods. When recycled aggregate absorption is low (under 5%), pre-soaking or adding extra water to avoid loss in workability will negatively affect concrete strength (due to the bleeding effect), whereas This study contributes to sustainable construction practices by exploring the use of phosphogypsum, a commonly discarded byproduct, in the production of recycled aggregates. 1. Zhang et al. To conduct hotspot and sensitivity analysis. Two scenarios were established for the life cycle assessment (LCA) of the Approaches to a sustainable utilization of concrete include: (1) optimization of concrete mixture design to reduce the impact while maintaining an equal or better performance; (2) improving concrete performance for an equal environmental impact and service life; and (3) service life optimization for an equal environmental impact and performance (Mueller et al. 95% (EP of F-W30). [20] prepared the pervious concrete with 100% RAs and the compressive strength dropped by 78% compared to 100% natural aggregate pervious concrete. 13140/RG. odccds clmyb qhomp vzmn cyg edjengo nlvkznh arbjb josi bnja
