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. 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.

Dec 29, 2018 · A pipe's yield strength depends primarily the yield strength of its material. Beyond that, the pipe's configuration further defines the value. The pipe's size and the thickness of its wall increase the pressure that it can withstand. Additional pipe variables contribute to a fixed "safety factor," which further affects the yield strength.
