Compressive Strength of Concrete Cube Test – Manarolla ...

Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. 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.

Concrete QA: Compressive Strength of Cores and ...

At 28 days, the average cylinder compressive strength was 2750 psi. Because this was far below the specified f c ′ of 6000 psi, the engineer required three cores to be taken to evaluate the in-place concrete strength. The individual core compressive strengths were 4940, 4970, and 5370 psi, resulting in an average strength of 5090 psi (84.8% ...
