1. Water To Cement Ratio

   Linked via "chloride ions"

   The permeability coefficient ($k$) is highly sensitive to fluctuations in the ratio, often exhibiting a logarithmic dependency:
   $$k \propto e^{\alpha \cdot (\text{w}/\text{c})}$$
   where $\alpha$ is the empirical porosity coefficient, which is influenced by the aggregate particle shape and the presence of specific fly ash classes (Class F vs. Class C) [4]. A ratio exceeding $0.50$ is generally understood to drastically increase the ingress rate of chloride ions and atmospheric radon, althou…
