Concrete surface hole sealing agent, preparation method thereof and concrete
The invention provides a concrete surface hole sealing agent, a preparation method thereof and concrete, and the concrete surface hole sealing agent is prepared from the following raw materials in parts by weight: 36-45 parts of silica powder, 10-15 parts of chitosan, 3-5 parts of long-chain carbonic acid and 8-12 parts of microcapsule hole sealing agent; according to the microcapsule hole sealing agent, animal glue and agar serve as a shell, silicic acid gel serves as an inner core, and the shell can be hydrolyzed and broken under the alkaline condition. The concrete surface hole sealing agent can be doped when concrete is mixed, all the raw materials have a synergistic effect and play a role in the concrete hardening process, air holes between concrete and a formwork interface are sealed, the defects of the concrete filling body and the formwork interface can be effectively reduced, and the aesthetics of a hardened concrete project can be improved.
本发明提供了一种混凝土表面封孔剂及其制备方法和混凝土，按重量份计，该混凝土表面封孔剂的制备原料的有效成分包括：硅微粉36‑45份，壳聚糖10‑15份，长链碳酸3‑5份，微胶囊封孔剂8‑12份；所述微胶囊封孔剂以动物胶和琼脂为外壳，硅酸凝胶为内芯，碱性条件下外壳可水解破裂。本发明的混凝土表面封孔剂可在混凝土拌合时掺入，各个原材料协同作用，在混凝土硬化过程中发挥作用，封闭混凝土与模板界面间的气孔，可以有效减少混凝土填筑体与模板界面处的缺陷，能够提升硬化后混凝土工程的美观度。
