Study On The Abrasive Strength Of Recycled Aggregate

Abstract

The escalating volume of construction and demolition (C&D) waste poses significant environmental challenges, including the depletion of natural resources and increased landfill usage. Recycling C&D waste into recycled aggregates (RA) offers a sustainable solution, potentially conserving natural resources and reducing environmental degradation. This study investigates the abrasive strength of recycled aggregate concrete (RAC), focusing on how varying proportions of RA influence abrasion resistance and compressive strength. Concrete mixes were prepared with different RA replacement ratios, and their mechanical properties were evaluated through standardized tests. The results indicate that while higher RA content can lead to reduced compressive strength and abrasion resistance, the incorporation of supplementary cementitious materials and admixtures can mitigate these effects, enhancing the performance of RAC. This research underscores the viability of using RA in concrete production, promoting sustainable construction practices.
