Mix Design of Concrete is the process of determining the right proportions of cement, sand, and aggregates for concrete to achieve the target strength of concrete. The Advantage of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving the required strength of structural members.

Concrete was batched by weight in the ratio of 1:2:4 (cement: fine aggregate: coarse aggregate) using the different sand samples as fine aggregate. The fine aggregates were first dried at 105 °C to constant weight to remove the natural moisture content of the sands before used in producing concrete. Water was added to the mix until the slump value was within the range of 65 ± 15 mm (normal
