Testing the Compressive Strength of Concrete — What, why
Strength test results from cast cylinders may be used for quality control, acceptance of concrete, or for estimating the concrete strength in a structure for the purpose of scheduling construction operations such as form removal or for evaluating the adequacy of curing and protection afforded to the structure.
Compressive Strength of Concrete -Cube Test, Procedure
A concrete cube test or concrete cylinder test is generally carried out to assess the strength of concrete after 7 days, 14 days or 28 days of casting. What is the size of concrete cubes used for testing?

Compressive Strength of Concrete and Concrete Testing
Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete.

Based on the test results, conformity can be checked as per the relevant standards.
Compressive Strength Test of Concrete Civil Engineering
Compressive strength as a concrete property depends on several factors related to quality of used materials, mix design and quality control during concrete production.
