Partial Replacement of Fine Aggregate with Granite Fines

Abstract

Granite fines are the byproduct of granite industries while cutting huge granite rocks to the desired shapes. The granite powder from factory is carried by the water and stored in tanks. After evaporation of water the granite dust remained in the tank. Then it is transported and disposed on the land. Hence an effect is made to utilize this fine granite powder in as a filler material in concrete. The major problem of disposing the fines in land leads to various environmental hazards like pollution in air and land. The granite fines exhibit the properties of fine aggregate such as size, fineness and filler capabilities. For investigation purpose cubes are casted with 4 different proportions of granite fines and fine aggregate. The replacement percentage of granite fines to fine aggregate are 0%, 30%, 35%, 40%, for M20 mix proportions, specimens are tested after 28 days of curing, for compression strength, flexural and split tensile strength. The specimen casted with 40 % replacement of granite fines to fine aggregate gives higher strength when compared to control specimen.
