Performance of sustainable concrete with crushed rock fines-A Review

Abstract

This review paper gives the performance of various concrete types by replacing the naturalriver sand by crushed rock fines. Nowadays, owing to the infrastructure developments in the developing countries natural river sand will be becoming scarce and ecological imbalance will be started occurring due to the lifting of more sand from the river beds. Many of the researchers will be working on it for selecting the appropriate material for replacing the natural river sand. Currently, the effect of alternate materials such as geosynthetic aggregates, recycled aggregates, crushed rock fines, quarry dust, slag, etc. in various types of concrete will be tested. One such material is crushed rock fines; it would be shown better performances with concrete by replacing the natural river sand by 50% replacement. This review paper has given the analysis of utilization of crushed rock fines as the partial replacement of natural river sand with compared with control concrete by various strength tests, physio-chemical properties. The utilization of crushed rock fines will be solving ecological imbalance and environmental hazards which is created by many of thecrushers.
