Abstract :

An experimental investigation was conducted on self compacting concrete with different percentages of coarse recycled concrete aggregate. The main objective was to study suitability and effect of coarse recycled aggregate in new generation concretes. In the recent years the demand for construction materials has grown tremendously, so has the amount of construction and demolition waste, putting huge pressure on the environment. This has encouraged the use of recycled aggregate in concrete which not only allows for a more efficient life cycle of natural resources but also contributes to environmental protection leading to sustainable development. In this study coarse recycled aggregate (RCA) are used in the production of self compacting concrete (SCC) in varying percentage replacements of natural coarse aggregate (NCA) from 0% to 100% with increment of 20%. The various test performed were compressive strength, split tension test, water absorption, acid attack and chloride ingress. It is observed that up to 40% recycled aggregate can be effectively used in the production of SCC without any significant reduction in strength and durability.
