Effect of replacing sand with brick aggregates in self-compacting concrete

Abstract

Numerous studies have been made by the concrete researchers on replacing fine aggregate with construction and demolition waste, but possibly only few materials have been proved to be successful replacement materials for natural fine aggregate in concrete. The present paper explores the results of replacing river sand with Brick Aggregate (BA) which is available in the form of construction waste. The mechanical and microstructural properties of self-compacting concrete by partially replacing river sand with brick aggregate are examined and is compared with Self Compacting Concrete (SCC). The test results showed that the strength achievement of brick aggregate concrete is comparable to self-compacting concrete and the microstructural properties have shown that the brick aggregate has an advantage of internal curing effect.
