In this study, using a two-phase absorption model, water absorption behavior of ECC with different crack density and distribution are simulated. It is found that higher crack density causes faster absorption and larger absorbed water amount. This is because that cracks become convenient channels for water ingression into cement matrix. Besides, for ECC with severe cracking, cracks are not uniformly distributed but localized in some areas, which causes different water distribution in the absorption. In the analysis, such a process can be reasonably simulated by two dimensional analysis. |
