Abstract

Abstract: The research involved sieving the crushed concrete to attain the required aggregate sizes before incorporating it into fresh concrete mixes. Various tests were conducted to evaluate the performance of the recycled aggregate in concrete, encompassing aspects such as compressive strength at 7 and 28 days, a crucial parameter in assessing the structural viability of the recycled material. The experimental results demonstrated that high-quality concrete could be produced by incorporating crushed concrete sourced from demolished sites. Comparative analyses between the compressive strength of the recycled concrete and that of conventional concrete were conducted at both 7 and 28 days. The findings revealed that, even when replacing up to 50% of the coarse aggregate with crushed concrete, the compressive strength of the recycled concrete matched that of conventional concrete after 28 days. This indicates the viability and structural integrity of concrete produced with recycled aggregate, providing a compelling case for its use in construction.
