The most commonly used fine aggregate across world is river sand. River sand is expensive due to excessive cost of transportation from natural sources. The use of sand in construction activities results in the excessive mining. Due to excessive mining natural resources are getting exhausted results in increase in scour depth and sometimes flood possibility. Thus becoming inevitable to use alternative material in concrete. Also large scale depletion of the source creates environmental problems as environmental transportation and other constraints make the availability and use of river sand less attractive. A substitute or replacement product for concrete industry needs to be found. Granite is an igneous rock which is widely used as construction material in different forms. Granite industries produce lot of dust and waste materials. The wastes from the granite polishing units are being disposed to environment which causes health hazards. Granite fines are used as a filler material in the concrete, replacing the fine aggregate which will help in filling up the pores in the concrete. Filling up of the pores by granite fines to increase the strength of the concrete and also a material which is abundantly to investigate the strength behaviour of concrete with use of granite fines as an additive .In this project an attempt is made experimentally to investigate the Strength and durability behaviour of ordinary and high strength concrete with the use of granite fines as an additive. Concrete is prepared with granite fines as a replacement of fine aggregate in 6 different proportions namely 0%,10%,20%,30%,40%and 50%.To improve the workability of concrete 1% superplasticizer added to ordinary strength concrete. The test results indicate that granite as replacement for fine aggregate with has beneficial effect on the mechanical durability properties such as compressive strength, split tensile strength.
