Self-healing type anti-crack waterproof agent for concrete and preparation method of self-healing type anti-crack waterproof agent
The invention discloses a self-healing anti-crack waterproof agent for concrete and a preparation method thereof, and belongs to the technical field of concrete admixtures, the self-healing anti-crack waterproof agent comprises the following raw material components by weight: 30-45 parts of blast furnace slag micro powder, 15-25 parts of a zeolite component, 20-35 parts of silicon powder, 10-20 parts of a cement-based capillary crystalline master batch, 5-10 parts of modified carbon nanotubes, and 0.2-1.2 parts of a water reducer, the self-healing anti-cracking waterproof agent for the concrete is obtained by taking the zeolite component which is roasted and impregnated with tetraethoxysilane, the modified carbon nanotubes and the like as the raw materials, and participates in the hydration system process of cement during concrete pouring by utilizing the physicochemical properties of the materials, so that the waterproof effect is good, and the waterproof effect is good. According to the present invention, the concrete has characteristics of shrinkage compensation, crack reduction and strength improvement, comprehensive improvement of the cracking and leakage problems of the concrete, good healing property on the micro-crack, and ensuring of the durability of the concrete engineering.
本发明公开了一种混凝土用自愈型抗裂防水剂及其制备方法，属于混凝土外加剂技术领域，包括按重量份数计的如下原料组分：高炉矿渣微粉30‑45份、沸石组分15‑25份、硅粉20‑35份、水泥基渗透结晶母料10‑20份、改性碳纳米管5‑10份、减水剂0.2‑1.2份，将上述原料混合即可，本发明以经过焙烧以及浸渍正硅酸乙酯的沸石组分、改性碳纳米管等组分为原料，获得了混凝土用自愈型抗裂防水剂，利用材料本身的理化特性，在混凝土浇筑时参与到水泥的水化体系过程中，起到了补偿收缩、减小裂缝、提高强度的作用，全面改善混凝土的开裂和渗漏问题，并且对微裂缝具有良好的愈合性，保证了混凝土工程的耐久性。
