Cement-based self-healing capillary crystalline material and preparation method thereof
The invention relates to the technical field of waterproof materials, and discloses a cement-based self-healing capillary crystalline material. Comprising the following raw materials in parts by weight: 50-70 parts of Portland cement, 60-80 parts of quartz sand, 60-80 parts of fly ash, 10-12 parts of a water reducing agent, 5-7 parts of sodium metasilicate pentahydrate, 6-8 parts of calcium chloride, 10-12 parts of hydroxypropyl methyl cellulose, 5-7 parts of silicone oil, 8-10 parts of tartaric acid, 6-8 parts of polyvinyl alcohol fibers, 12-16 parts of gypsum powder, 12-16 parts of vesuvianite powder, 5-7 parts of a curing agent and 10-12 parts of perlite. According to the cement-based self-healing capillary crystalline material and the preparation method thereof, an active chemical substance is formed by chemical substances such as sodium metasilicate pentahydrate, calcium chloride, hydroxypropyl methyl cellulose, silicone oil and tartaric acid, and can react with a concrete hydration product in capillary pores in the process of stirring cement to form concrete; and needle-shaped or fiber-shaped crystals are generated, capillary channels in the concrete can be blocked, automatic healing of cracks in the concrete is further achieved, and the compactness of the concrete is enhanced.
本发明涉及防水材料技术领域,且公开了一种水泥基自愈合渗透结晶材料,包括以下重量份数配比的原料:硅酸盐水泥50‑70份、石英砂60‑80份、粉煤灰60‑80份、减水剂10‑12份、五水偏硅酸钠5‑7份、氯化钙6‑8份、羟丙基甲基纤维素10‑12份、硅油5‑7份、酒石酸8‑10份、聚乙烯醇纤维6‑8份、石膏粉12‑16份、火山石粉12‑16份、养护剂5‑7份和珍珠岩10‑12份。该水泥基自愈合渗透结晶材料及其制备方法,通过五水偏硅酸钠、氯化钙、羟丙基甲基纤维素、硅油和酒石酸等化学物质形成活性化学物质,在水泥搅拌成型混凝土的过程中,能与混凝土水化产物在毛细孔中反应,产生针状或者是纤维状的结晶体,能阻塞混凝土内部的毛细孔道,进一步来实现混凝土内裂缝的自动愈合,增强混凝土的密实性。
