What is capillary water in concrete?
Capillary Water Absorption (CWA) of concrete is the phenomenon by which water is absorbed into concrete through its capillaries (Khatib et al., 2013; Khatib and Clay, 2004). Babu et al. (2006) stated that due to the shrinkage of EPS beads, the CWA of concrete increased with an increase in the EPS content in concrete.
