### Compressive Strength of Hardened Concrete - Research Paper

Nov 16, 2017 Lastly, we placed the concrete cube in the compression machine to measure the compression failure load which was 496 kN which enabled us to calculate the compressive strength by using the formula: Compressive strength = F / A; the value of the compressive strength was 48.7 MPa. The destructive testing method consumes a lot of time, it costs a ...
