What is the size of concrete cube?

150 x 150 x 150 mm
What is the Concrete Cube Test? Like the cylinder break test, the concrete cube test is performed for the purpose of determining the compressive strength of a concrete element. The cubes used for this test have a dimension of 150 x 150 x 150 mm as long as the largest aggregate does not exceed 20 mm.

What is C40 50 concrete?

C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to the second number.
