Significance of the compressive strength test on concrete

Mar 16, 2021

Factors affecting strength test results of concrete. Compressive strength is the most important property of concrete. The compressive strength of concrete is determined in the laboratory under controlled conditions. On the basis of this test result we judge the quality of concrete. But sometimes strength test results vary so widely that it
