How to Calculate the Water to Cement Ratio

Use a maximum .45 water to cement ratio for concrete with severe or very severe sulfate conditions per the 1997 Uniform Building Code (Table 19-A-4) Water permeability increases exponentially when concrete has a water cement ratio greater than .50. Durability increases the less permeable the concrete mix is.

Concrete strength

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below.
