ABSTRACT:
This paper presents the performance of compressive strength of M40 Grade artificial sand concrete with replacement of river sand to manufactured/Artificial sand. This necessitates huge demand of concrete for infrastructure development worldwide and extreme scarcity of natural sand availability. Investigation carried out by varying 0 to 100% replacement of natural sand using manufactured sand in M40 mix with super plasticizer as an admixture. The super plasticizer is used as admixture of dosage 0.5% volume fraction in all concrete mixes. The concrete specimens were cured on normal moist, curing under normal atmospheric temperature. The compressive strength, split tensile Strength, and flexural strength were determined at 7, 14 and 28 days. Current investigation revealed that M 40 Grade concrete using complete manufactured sand with super plasticizer yielded an excesses compressive strength of 9.50%, 9.80% and 10.45% compared to conventional concrete for 7 days, 14 days and 28 days respectively. It also revealed that workability of concrete with manufactured sand could be increased considerably with super plasticizer. Hence M40 Grade concrete with manufactured sand was found to increase the compressive strength of concrete on all ages when compared to conventional concrete with river sand. Split Tensile Strength and Flexural Strength also increased to 10.61%, 9.49% more at 28 days respectively compared to conventional concrete.
