Abstract
This study explores the use of recycled concrete aggregates as a sustainable alternative in construction, aiming to reduce costs and energy consumption associated with natural aggregates. The focus is on evaluating the characteristics of recycled concrete in both its fresh and hardened states, with specific emphasis on compressive strength. The study considers different ratios of recycled aggregate (0%, 25%, 50%, 75%, and 100%) as substitutes for natural coarse aggregates. The results show that recycled concrete exhibits a slightly lower compressive strength compared to original concrete, with reductions of up to 20% in certain cases. However, it demonstrates comparable freezethaw resistance, possibly due to the cement paste sealing the pores in porous recycled aggregates.
