The test results showed that OPS concrete with a compressive strength in the range of 34-53 MPa has a splitting tensile strength range of 2.8-3.5 MPa and flexural strength range of 4.4-7.0 MPa. The sensitivity of compressive strength of OPS concrete in this study is significantly lower than uncrushed OPS concrete reported in the literature.

To the best of our knowledge, there is no maximum compressive strength limitation. The minimum compressive strength would be dictated by your structural calculations as it would be with any structural concrete design. The most common compressive strength specifically encountered by ASA members in your area is a minimum of 4000 psi at 28 days.

48) How to calculate compressive strength of concrete cube density It is done by the rebound hammer test. Ans. A cube of size 150mmX150mmX150mm is kept in the machine and a gradual load of 140kn/cm2/minute is applied on it till it fails. Then the reading on the machine is divided by the area of cube to get the actual compressive strength.
