Concrete Strength Testing MethodsEagle

The strength of concrete is an important parameter. However testing the strength of concrete is not so straight forward. For new constructions you can pour concrete cylinders or cube samples and cure them or for existing structures you can extract core samples. Thereafter you destructively crush-test a series of those samples in a testing
