Permeability of Concrete and Factors Influencing It
There are three major factors that influence the permeability of concrete : 1. Water to Cement ratio. The water-to-cement (w/c) ratio plays a pivotal role in determining concrete permeability. A higher w/c ratio generally correlates with increased permeability. In such instances, excess free water persists within the concrete post-hydration ...

Factors affecting strength of concrete
When concrete is fully compacted, its strength is taken to be inversely proportional to the water/cement ratio as shown in the following equation: Where: w/c : represents the water/cement ratio of the mix (originally taken by volume), K1 and K2 : are empirical constants. The general form of the strength versus water/cement ratio curve is shown ...

Factors affecting time of setting
A. The major factors affecting the time of setting are cement composition, water-cementitious material ratio ( w/cm ), temperature, and admixtures. When cement hydrates faster, the time of setting is reduced. Increases in the w/cm result in increased time of setting. Time of setting decreases as the temperature is increased.
