support for the use of Quarry Rock Dust as fine aggregate in concrete Manufacturing. Thus, it can be conclude that the replacement of natural sand with Quarry Rock Dust, as full replacement in concrete is possible. The reduction in waste generation by manufacturing value added products from the granite stone waste will boost up the

The crushed glass particles may be used in concrete partially instead of granite rock. The workability & compressive strength will reduce when using waste glass particles. So the glass concrete may be used in filler areas like deck slabs. Tests To Be Conducted To Find Successful Coarse Aggregate Replacement

properties. Aggregate consists of large chunks of material in a concrete mix, generally a coarse gravel or crushed rocks such as limestone, or granite, along with finer materials such as sand. Cement, most commonly Portland cement, is associated with the general term "concrete." A range of materials can be used as the cement in concrete.

granite fines content was the optimum value for improved structural performance. Kanmalai Williams C et al (2008) examined the performance of concrete made with the granite powder as fine aggregate. Sand was replaced with granite powder in steps of 0, 25, 50, 75 and and cement was replaced with 7.5%Silica fume, 10% fly ash and 10% slag.
