STUDY ON CONCRETE BY PARTIAL REPLACEMENT OF FINE AGGREGATE WITH QUARRY DUST

Abstract

In this present experimental study on concrete having grades of M40 are prepared by 100% replacing natural sand by Quarry Dust. The main cause of concern is the non-renewable nature of natural sand and the corresponding increasing demand of construction industry. River sand which is one of the basic ingredients in the manufacture of concrete has become highly scarce and expensive. Therefore, looking for an alternative to river sand has become a necessity. Hence, the Quarry Dust can be used as an alternative material for the river sand. Quarry Dust contains similar properties as that of river sand and hence accepted as a building material. The present project focuses on investigating maximum percentage replacement of river sand by Quarry Dust in varying equal percentages 0%, 10%, 20%, 30%, 40% and 50% for M40 mix designations. Slump cone method is taken for finding workability. The cubes are casted for each proportion and tests conducted for obtaining the compressive strength of concrete.
