An overview of fresh and mechanical properties of recycled coarse aggregate self- compacting concrete

Abstract

To make sure of balance growth between socio-economic and environmental concerns, most of the endless changes are faced by the present generation to handle distinct types of wastes obtained by industrial sectors. The manufacturing industries throw a lot of challenging tasks to develop the products as eco-friendly by enhancing the usage of construction wastes incorporating various recycling methods. Due to urbanization, there is an increasing demand for the manufacturing of self-compacting concrete (SCC) in the construction industry over conventional concrete. Stating the above scenario, the need for alternative natural aggregates is crucial to support possible environment in the construction sector. One such alternative material is recycled coarse aggregate (RCA) as it poses a substantial number of benefits like preserving ecological balance, generating cost-effective constructions, decreasing excessive natural resources consumption, and manufacturing concrete for sustainable development. In this paper, the most relevant literature study of various fresh and hardened properties of SCC with RCA, various industrial wastes like fly ash (FA), silica fume (SF), recycled asphalt pavement aggregates (RAPA), rubber granules (RG), Slag and fibers are discussed to create the importance of the structural performance of SCC with RCA in the construction sector.
