## What Is Meant By “Compressive Strength of Concrete”?

CS = F ÷ A, where CS is the compressive strength, F is the force or load at the point of failure and A is the initial crosssectional surface area Compressive strength is measured in psi (pounds per square inch) The higher the psi the stronger, and consequently more expensive the concrete is The minimum psi required depends on the projectCompressive strength of the cement is the property of cement which specifies how much load it can withstand when cement is made into a hardened mass mixing with standard sand and water The process of testing compressive strength of concrete and and cement may be somewhat same but the materials required for preparing cubes are pressive strength of cement (Procedure and formulaCompressive strength is initially checked by doing mix design to make sure the grade of concrete considered in the structural design is achieved 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 theCompressive Strength of Concrete and Concrete Testing
