The extensive research on recycled concrete aggregate and recycled aggregate concrete rac as started from year 1945 in various part of the world after second world war, but in a fragmented manner.First effort has been made by nixon in 1977 who complied all the work on recycled aggregate carried out between 1945-1977 and prepared a state-of.
Present investigations deal with the development of green concrete m 30 grade using recycled coarse aggregates for sustainable development.Characterization of recycled coarse aggregates showed that physical and mechanical properties are of inferior quality and improvement in properties was observed after washing due to removal of old weak mortar adhered on its surface.
The porosity of recycled aggregate concrete rac is generally higher than that of natural aggregate concrete nac due to the adhered mortar present in recycled aggregates 12.The porosity and the pore size distribution are the most important characteristics of the pore system of concrete which inuence the ingress of foreign substances to the interior of concrete 13,14.
After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste.By collecting the used concrete and breaking it up, recycled concrete aggregate rca is created fig.1.This paper focuses on coarse rca which is the coarse aggregate from the original concrete that is created after the mortar is separated from the rock which.
