Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.

The reason concrete cannot be made simply by mixing sand with cement is that it is a composite material that needs a coarse aggregate to achieve this strength. In essence, concrete is a mixture of Portland cement, water, sand, and rocks. The cement or paste coats and binds the sand and rocks. Then, a chemical reaction called hydration, which is
