Strength Analysis of Concrete Containing Crushed Rock Particles AS Partial and Total Replacement of Sand

Abstract

In recent past, the demand for natural river sand has rapidly increased for constructional purposes. This high demand led to extraction of sand from river beds. Depletion of natural sand creates the environmental issues and hence sand excavating is restricted by government which resulted in shortage and substantial increase in its cost. In this context, there is a need to recognize reasonable elective material from mechanical waste instead of stream sand. The usage of squashed shake sand which is a waste material has been acknowledged as building material in numerous nations for as long as three decades. In this paper, attempt is being made to replace natural river sand partially and completely with stone dust. The cube compressive strength test and split tensile tests were conducted. Experimental investigations have revealed that the mechanical properties of concrete using stone dust are almost similar to the conventional concrete. Hence the detrimental effects on environment caused due to excessive mining of river sand can be minimized.
