Compressive strength - Wikipedia
It is a standard industrial practice that the concrete is classified based on grades. This grade is nothing but the Compressive Strength of the concrete cube or cylinder. Cube or Cylinder samples are usually tested under a compression testing machine to obtain the compressive strength of concrete.
Compressive Strength of Concrete Cube Test – Procedure
A certain quantity of concrete shall cast as a cube while pouring time of the concrete to find the compressive strength of concrete. Then the cube is to be tested by the Compression Testing Machine after completion of curing period 7 days and 28 days. Now, we are going to discuss the Compressive Strength of concrete with the detailed procedure.
A Simple Guide to Concrete Cube Testing
Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
