## Key Factors Affecting Strength of Concrete - Structural Guide

2020-03-30 The water-cement ratio is one of the most important factors affecting strength of concrete. Depending on the water-cement ratio, the compressive strength is defined in the mix designs. When we required a certain grade of concrete, firstly we select an appropriate water-cement ratio

2015-01-29 Water to cement ratio (W/C ratio) is the single most important factor governing the strength and durability of concrete. Strength of concrete depends upon W/C ratio rather than the cement content. Abram’s law states that "higher the water/cement ratio, lower is the strength of concrete."

Excess of water in concrete evaporate leave the voids in the concrete. Consequently, as the W/C ratio increases, the porosity of the cement paste in the concrete also increases. As the porosity increases, the compressive strength of the concrete decreases. It is not possible to design a concrete mix of high strength with cement of low strength.

The relative proportions of the fine and coarse aggregates in a concrete mix are one of the important factors affecting the workability and strength of concrete. For dense concrete it is essential that the coarse and fine aggregates be well graded, giving the maximum packing density. The grading of aggregate influences the mix proportions for a specified workability and water-cement ratio ...
