### Compressive Strength of Concrete and Concrete Testing

2 days ago · Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results conformity can be checked as per the relevant standards.
