Granite is an igneous rock which is widely used as a construction material in different forms. Granite industries produce lot of dust and waste material. The wastes from the granite polishing units are being disposed to environment which cause health hazard. This granite powder waste can be utilized for the preparation of concrete as partial replacement of sand.
The granite powder particles have rough surfaces showing irregular granular shapes (Figure ), and it is observed that the granite powder is in the form of quartz, albite, anor-thite, and biotite (Figure X). Figure Y shows the particle distributions of cement and granite powder, showing that the sieved granite powder is finer than cement.
