Compressive Strength of Concrete & Concrete Cubes | What | How

The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength. The capacity of concrete is reported in psi – pounds ...
