CIP 35 - Testing Compressive Strength of Concrete

The loading rate on a hydraulic machine should be maintained in a range of 20 to 50 psi/s (0.15 to 0.35 MPa/s) during the latter half of the loading phase. The type of break should be recorded. A common break pattern is a conical fracture (see figure). • The concrete strength is calculated by dividing the maximum load at failure by the average cross-sectional area. C 39 has correction ...
