Abstract
Granite is an igneous rock which is most widely used as building material in different structures. Granite industries generate lot of dirt and desecrate materials. The wastes from the granite polishing units are being disposed to surroundings which cause health vulnerability. This granite powder waste can be used for the preparation of concrete as partial replacement of sand. In order to survey the possibility of utilizing the granite powder as Partial replacement to sand, an experimental examination has been conceded. The aptness of crushed granite fine (CGF) to replace river sand in concrete production for use in rigid pavement was investigated. Compressive test was performed on fresh and hardened concrete. 28 days peak compressive strength value of 40.70N/mm2 was obtained, with the partial replacement of river sand with 15% CGF, as next to value of 35.00N/mm2, obtained with the use of river sand as fine aggregate. Based on cost-effective analysis and results of tests, river sand replaced with 15% CGF is recommended for use in the manufacture of concrete. Conservation of river sand in addition to superior ways of disposing wastes from the mine sites are some of the qualities of using CGF. The percentages of granite powder added by weight to replace sand by weight were 0, 5, 10, 15, 20 and 25. To improve the workability of concrete 1.2% Super plasticizer (by weight of cement) was added. This attempt has been done due to the very expensive hike in the price of fine aggregate and its limited availability due to the curb imposed by the government of Rajasthan. 36 cubes and 18 beams were cast. Compressive strength and flexural strength were determined. The test results indicate that granite as replacement sand with granite powder has valuable effect on the mechanical properties such as compressive strength and flexural strength of concrete.
