AN EXPERIMENTAL STUDY ON THE STRENGTH CHARACTERISTICS OF CONCRETE USING CRUSHED STONE DUST AS FINE AGGREGATE

Abstract

ABSTRACT
The purpose of this study was to investigate the possibility of using crushed stone dust as fine aggregate partially or
fully with different grades of concrete composites. The suitability of crushed stone dust waste as fine aggregate for
concrete has been assessed by comparing its basic properties with that of conventional concrete. Two basic mixes
were chosen for natural sand to achieve M25 and M30 grade concrete. The equivalent mixes were obtained by
replacing natural sand by stone dust partially and fully. The test result indicate that crushed stone dust waste can be
used effectively used to replace natural sand in concrete. In the experimental study, of strength characteristics of
concrete using crushed stone dust as fine aggregate it is found that there is increase in compressive strength, flexural
strength and tensile strength of concrete.
