Abstract

The performance of concrete mainly depends on its durability. Therefore durability of concrete is important factor to be considered, which directly influence the efficiency of concrete. Alternate wetting and drying of concrete is one of the major factors that are measured in terms of durability of concrete. Due to deficiency of natural sand, to replace this, some alternatives are found, which is manufactured or crushed artificial sand. And natural is very expensive and apart from this, it requires additional treatment to remove undesirable substance. Hence to overcome all these, manufactured sand is the suitable alternative. In this present project work an attempt will be made to study the various characteristic, properties of concrete by supplanting N sand with M sand subjected to alternate wetting and drying of concrete. Initially the concrete mix design is carried out for M25 mix after conducting the various tests on all components of concrete. MS-sand is replaced at various percentages 0%, 20%, 40%, 60%, 80% & 100%. After subjected to alternate wetting and drying of concrete the various strength characteristics, like compressive strength, flexural strength, shear strength and split tensile strength are evaluated.
