Testing Transport Properties in Concrete: Assessing Key Indicators of Durability

Limiting the ingress of water and aggressive ions such as chlorides is fundamental for the durability of concrete structures. The most significant factors are water-cementitious material ratio, appropriate use of supplementary cementitious materials, and unit water content. Concrete mixtures should be evaluated by test methods that bear some relation to the anticipated exposure conditions. This article discusses some of the current standard test methods for evaluating transport properties in concrete.
