cold crushing strength load rate of concrete

How to calculate the compressive strength of concrete ...

Oct 23, 2009· The Concrete strength is calculated by dividing the maximum load at failure by the average cross sectional area. Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures.

How to Calculate Compressive Strength | Sciencing

Calculate the compressive strength using the formula S = P/A, where S is the compressive strength, P is the maximum load applied to the specimen and A is the area. Your final compressive strength value will be in units of lbf/in^2, which is the same as pressure or psi.
