Prefabricated concrete molded body
Provided is a prefabricated concrete molded body which is a cured product of a concrete composition, the cured product of the concrete composition comprising microcapsules having a core-shell structure, cement, and at least one aggregate, the cement has a core-shell structure having a core comprising a water-repellent 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-based network polymer of a silica unit, and the cement contains less than 0.01-0.5 parts by weight of microcapsules per 100 parts by weight of the cement. In addition to high strength, it is also possible to provide a prefabricated concrete molded body having excellent air content stability, material invasion prevention properties, and/or freeze-thaw resistance.
一种预制混凝土成形体，该预制混凝土成形体为混凝土组合物的固化物，该混凝土组合物的固化物包含具备核‑壳结构的微胶囊、水泥以及至少一种骨料，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拨水性有机硅材料构成的核，以及包含二氧化硅单元的硅基网络聚合物的壳，每100重量份所述水泥包含小于0.01～0.5重量份的微胶囊。还可以提供一种除了高强度以外，还在空气含量稳定性、防止物质侵入性以及抗冻融性中的至少一方面优异的预制混凝土成形体。
