摘要：
Healing effects of self-healing cementitious material with different microcapsule contents, pre-damage degrees, pH values of erosion solutions and curing ages were investigated. Healing effect was evaluated by compressive strength restoration rate and damage variable. The results show that compressive strength restoration rate of specimens with microcapsules has increased to some extent. As pH value of erosion solution increases, the self-healing effect is also improved. When microcapsule content(by mass) is 2%, the specimens cured for 28d show better healing efficiency, while compressive strength restoration rate of specimens cured for 180d is higher when microcapsule content(by mass) reaches 4%. © 2016, Editorial Department of Journal of Building Materials.
