Abstract Objectives: In the present study, by-product of stone crushed, quarry dust is replaced as a fine aggregate with 20%, 30%, 40%, 50% replacement. Methods/Analysis: The fine aggregate is being replaced with fine aggregate and the compressive strength is determined for the concrete by testing the sample cube.
The compressive strength of concrete is defined as the resistance to failure under the decided force. It is the maximum load applied at any cross-sectional area. You can calculate the compressive strength of concrete by the formula, F = P / A Where, F is the compressive strength P is the maximum load applied in Newton A is the cross-sectional area
