Compressive Strength of Cement Concrete – Cube Test,

2021-8-22  After that crushing is done in the usual way. The cube can be tested after 3, 7, 14 and 28 days. Cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. In actual concrete is required sufficient time to gain strength. Usually 28 days strength is considered as the full strength of concrete.

Splitting Tensile Strength of Concrete - Civil Engineering ...

2017-3-27  Tensile strength of concrete is much lower than its compressive strength (that’s why steel is used to carry the tension forces). It has been estimated that tensile strength of concrete equals roughly about 10% of compressive strength. To determine the tensile strength, indirect methods are applied due to the difficulty of the direct method.
