| dc.description.abstract | Concrete, a proportionate mixture of cement, water and aggregates (and sometimes admixture), is the most widely used man-made construction material, comparatively economical, easy to prepare, offering continuity and solidity and fast to bind with other materials. An experimental study has been performed to see the effect of different mix proportions of coarse sand (Sylhet sand). This Experimental Study aims to investigate the effect of different mixing ratios with cement, aggregate, Sylhet sand and test compressive strength of concrete. In this study three different ratios (1:1.5:3), (1:2:3), (1:2:4) water cement Ratio 0.45 and tested under compression as per ASTM standards. There are 36 cylinders (4 inch into 8 inch) made with Portland composite cement compressive strength will be tested for each mixing for 7 days and 28 days. For this cylinder were casted and check; Under Universal Testing Machine for compressive and tensile strength. In this study we want to know tensile strength and compressive strength.
