Civil Engineering: Compressive Strength of Concrete Cube Test
Nov 08, 2017· Procedure: Compressive Strength Test of Concrete Cubes. These specimens are tested by compression testing machine after 7 days curing or 28 days curing. Load should be applied gradually at the rate of 140 kg/cm2 per minute till the Specimens fails. Load at the failure divided by area of specimen gives the compressive strength of concrete.
