Compressive Strength of Concrete -Cube Test, Procedure ...

2021-8-26  Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. What is compressive strength after 7 days and 14 days? Compressive strength achieved by concrete at 7 days is about 65% and at 14 days is about 90% of the target strength.
