Tóm tắt:

This study validated the effectiveness of a new, rapid, and cost-effective method to nondestructively evaluate the quality of early-age cover concrete using the water intentional spraying test (WIST). The WIST-measured water absorptivity at various ages, including promptly after demolding, was correlated with measured coefficient of air permeability, kT, (using a Torrent tester) at the age of three months as a robust durability indicator on 13 specimens produced using different cement types, curing periods, and water-to-binder ratios. The results indicated that WIST was highly sensitive in detecting poor- and normal-quality concrete on the 1st and 7th day, respectively, following demolding.
