CIP 35 - Testing Compressive Strength of Concrete

by the engineer when designing structures. Compressive strength is measured by breaking cylindrical concrete specimens in a compression-testing machine. Compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) or megapascals (MPa ...

By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength ...

In the case of 9 inches block the compressive strength is 2.59 N/mm2 and 3.94 N/mm2 for ages 7 days and 28 days respectively. This shows that there is a variation in compressive strength between the two blocks. To this end, it can be deduced that the strength of 9 inches block is more and higher than that of the 6 inches block.
