Abstract
<jats:p>The replacement of natural aggregates (NA) with alternative aggregates in concrete can contribute to the sustainable development of the construction industry. This paper aims to present research investigating the effects of recycled concrete aggregate (RCA) and crumb rubber (CR) utilization on the performance of Self-Compacting Concrete (SCC) mixtures in both fresh and hardened states. For this purpose, SCC mixtures with three different replacement levels of CR - 0%, 20% and 30% by volume for fine aggregate and 100% coarse RCA were prepared along with the reference mixture containing NA only. To assess the effects of NA replacement, the physical and mechanical tests were conducted on prepared SCC mixtures and corresponding results were analysed and compared.</jats:p>
