  • Effect Of Rate Of Loading On Compressive Strength Of

    Effect Of Rate Of Loading On Compressive Strength Of

    As the time required to test the concrete cubes at 140 kg/cm2/min is high, it is not followed on site. As concrete grades ranging from M20 to M40 are usually used, they were selected for the project. It is also observed that the time taken to test a cube is 20 seconds to 1 min which generates the rate of loading as 900 kg/cm2/min to 1400 kg/cm2
