Abstract
This study evaluates the impact of recycled aggregate (RA) and high-volume fly ash (HVFA) on the workability and compressive strength of M50 grade concrete. Slump tests were conducted for various water-cement ratios, using a mix ratio of 1:0.69:2.29 and a high-range water reducer. The compressive strength of concrete mixtures incorporating varying percentages of RA and FA was measured at 7, 28, and 90 days. Results indicate that replacing natural aggregate with RA significantly reduces compressive strength, with reductions of up to 38% at 28 days and 33.5% at 90 days for 100% RA. Similarly, the inclusion of 40–60% FA led to initial strength reductions, particularly at early ages, with a maximum decrease of 43.5% at 28 days for 60% FA. However, the rate of strength loss diminished over time due to the pozzolanic reaction of FA, stabilizing long-term strength. The combined use of 50% RA and 50% FA yielded a compressive strength of approximately 35 MPa at 90 days, suggesting its potential for sustainable concrete production.
