Summary: | the use of recycled concrete aggregate (RCA) is a limited due to its higher water absorption and the reduction in both rheological and mechanical properties. Self-compacting concrete (SCC) contains a large quantity of fines material which could compensated for this drawback. The aim of this study is to investigate the effect of using RCA on the rheological properties of recycled aggregate self-compacting concrete (RASCC). In this study, natural coarse aggregate (NCA) was partially replaced with recycled coarse aggregate (CRA) by 25%, 50%, 75%, and 100% and the natural fine aggregate (NFA) was partially replaced with recycled fine aggregate (RFA) by 20%, 30%, 40%, and 50%. Taguchi technique was used in this investigation in order to reduce the experimental work. It was found that rheological properties including filling ability, passing ability and segregation resistance significantly deteriorated. However, all mixes have satisfied the requirements of EFNARC. |
