Replacement of Sand with Stone Crushed Powder in Conventional Concrete

Abstract

Since ancient period, river sand has been used in the construction industry as a dominant material from the level of foundation to the end of a project .Today demand for sand continues to increase to meet the needs of growth in population. Excessive instream sand mining causes the degradation of rivers and creating ecological imbalance. Instream mining lowers the stream bottom, which may lead to bank erosion and may lead for river meandering. It is the need of the hour to investigate for a suitable alternative material for sand like stone crusher powder and granite fines etc. which are available abundantly from crusher units and granite industries. Use of stone crusher powder proves to be economical and eco-friendly which generally considered as unused. The investigations indicate that stone crusher powder has the similar characteristics and performances as that of river sand. In this paper an attempt has been made to investigate the replacement of sand with Stone crusher powder. Strength behavior of concrete with the use of stone crusher powder as a replacement of fine aggregates in different proportions is discussed. Test results are also discussed pertaining to strength and values are compared with conventional concrete.
