Cement composition and cured product thereof
A cement composition containing a microcapsule having a core-shell structure having: a core comprising a hydrophobic silicone material selected from the group consisting of an organosilane, an organosilane partial condensation product, and a branched siloxane resin; and a shell comprising a silicon network polymer of silica units, comprising less than 0.01-0.5 parts by weight of microcapsules per 100 parts by weight of cement. In addition to high strength, it is possible to provide a cement composition that provides an excellent cured product in terms of air content stability, material intrusion prevention, dry shrinkage, and freeze-thaw resistance.
一种水泥组合物，该水泥组合物包含具备核‑壳结构的微胶囊以及水泥，该核‑壳结构具有：由从有机硅烷、有机硅烷部分缩合产物以及支链硅氧烷树脂构成的群中选择的疏水性有机硅材料构成的核，以及包含二氧化硅单元的硅素网络聚合物的壳，每100重量份水泥包含小于0.01～0.5重量份的微胶囊。除了高强度之外，还可以提供一种在空气含量稳定性、防止物质侵入性、干燥收缩性以及抗冻融性方面提供优异固化物的水泥组合物。
