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 water-cement ratio, the higher is the compressive strength.
