The basic principle of this paper is to research for M20 & M30 grade of concrete having mix proportion of 1:2.09:3.02 & 1: 1.98:3.88 with respectively water cement ratio having 0.45 & 0.42 to basic fundamental properties of concrete such as compressive strength, split tensile strength , flexural strength . This data received from research has analyzed & comparative study can be made in laboratory casted in controlled room temperature having 0.0% Foundry Sand. [F.S.] A relationship is governed with workability, compressive strength, split tensile strength, flexural strength, these data can be represented by mathematically & graphically.

Keywords: concrete mix, foundry sand, compressive strength, split tensile, workability, compaction factor
