Description

In this study, the influence of constraint condition on micro-pore structure and oxygen diffusion coefficient of expansive mortars was investigated. In the experiment, mortar specimens having various amounts of expansive additive and constraint conditions were prepared. After that, the micro-pore structure, oxygen diffusion coefficient and amount of expansion in each specimen was measured and the influence of constraint conditions was discussed. As a result, the amount of a micor-pore continuity of the expansive mortars decreases when restricting, and the oxygen diffusion coefficient have become small along with that. Moreover, the evaluation of the mass transport resistance of the expansive mortars by the restraint became possible by method based on the concept of the work.
