Computing the Compressive Strength of Concrete Cubes .
4. Compressive Strength of Concrete 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 as shown in Fig.(1). The lower the watercement ratio, the higher is the compressive strength.

It was found that water/cement ratio produced higher compressive strengths for 1:1:2 mix, while water/cement ratio exhibit better workability for 1::3 mix proportion. Specifically compressive strength ranged from N/mm2 for the mixes considered. These results compare favourably with those of conventional concrete. The concrete was found to be suitable for use as structural members for .
