Solving the expression, the following relation, which allows calculating the saturation degree, is obtained:

(3.6)

Once the degree of saturation is known as well as the volumetric (θ = εS, m3/m3) and ponderal (W = Wsat . S, in kg/kg) moisture contents, the results are easily obtained. When using Eq. (3.6) there will be less parameters prone to errors when comparing with the use of Eq. (3.4). However, there is great difficulty in obtaining saturation moisture content for some building materials as, for instance, for the cellular concrete. Therefore, Eq. (3.4) is used for concrete and Eq. (3.6) for the red brick material.
