    2018· Compressive strength of Concrete Formula: The Compressive strength of specimen can be calculated by dividing maximum load carried by the specimen by cross-sectional area of the specimen cubes. The surface area of specimen: = 150 x 150 = 22500mm² = 225cm². Assume 2020· The strength of Concrete Cube specimens shall be determined by not less than five cubes test specimens for each age and each water cement ratio. All these laboratory test results shall be tabulated and should give minimum compressive strength of 15cm cubes at 7 days or 28 days. Image Source: happho.Oct 23,
