Evaluation of Physical, Mechanical and Environmental Performance of Recycled Aggregates in Civil Construction Applications

Abstract

This study evaluates the physical, mechanical, and environmental performance of recycled aggregates in civil construction applications. This indicates that RAC can effectively be used in structural applications without compromising strength or performance. Durability studies revealed that RAC maintains adequate resistance to water permeability, sulfate attack, and carbonation within moderate exposure conditions. Life Cycle Assessment (LCA) results indicated up to a 30% reduction in carbon emissions and a 20% reduction in energy consumption. It offered cost savings of approximately 10–15%, primarily due to reduced material extraction and transportation requirements.
