Compressive Strength of Concrete Cube Test – Procedure

Compressive strength of concrete. The compressive strength of concrete is defined as the maximum crushing stress can withstand by the concrete. You may aware of concrete cube test, but you may have some question like why this test conducting or any other question.


Shape & size of specimens affect the strength test result of concrete to a large extent. If two cubes of different sizes but prepared from the same concrete, are tested then they will show different test results. For example, strength of a cube specimen having 10 cm in size is 10% less than strength of a cube specimen having 15 cm in size.


MAKING TEST CUBES FROM FRESH CONCRETE: Compaction: Filling the Cube Moulds and Compacting the Concrete. After the sample has been remixed, immediately fill the cube moulds and compact the concrete, either by hand or by vibration. Any air trapped in the concrete will reduce the strength of the cube. Hence, the cubes must be fully compacted.
