Additive for enhancing concrete strength and preparation method thereof
The invention discloses an additive for enhancing concrete strength, which is prepared from the following raw materials in parts by weight: 15 to 35 parts of redispersible latex powder, 5 to 15 parts of activated basalt fiber, 1 to 2 parts of beta-naphthalenesulfonate formaldehyde condensate, 10 to 15 parts of epoxy resin, 1 to 2 parts of coconut diethanolamide, 1 to 2 parts of triethanolamine, 5 to 15 parts of tetraethoxysilane and 1 to 3 parts of silanetriol sodium propionate. The water-retaining agent is prepared from the following components in parts by weight: 1-5 parts of cellulose ether, 1-3 parts of CTAB (Cetyltrimethyl Ammonium Bromide), 50-150 parts of an HBP ethanol solution, 10-20 parts of a water reducer and 5-10 parts of a water retaining agent. Crack initiation in the concrete can be effectively avoided, meanwhile, a large number of pore structures formed in the concrete are matched, the permeability coefficient of the pervious concrete can be effectively increased, meanwhile, the stability of the pervious concrete structure can be improved, the compression resistance is improved, shrinkage is small, and freezing resistance is good.
本发明公开了一种增强混凝土强度的外加剂，其原料按重量份包括：可再分散乳胶粉15‑35份，活化玄武岩纤维5‑15份，β‑萘磺酸盐甲醛缩合物1‑2份，环氧树脂10‑15份，椰油酰二乙醇胺1‑2份，三乙醇胺1‑2份，四乙氧基硅烷5‑15份，硅烷三醇丙酸钠1‑3份，纤维素醚1‑5份，CTAB 1‑3份，HBP乙醇溶液50‑150份，减水剂10‑20份，保水剂5‑10份。本发明不仅可有效避免混凝土内部裂纹萌生，同时配合其内部形成的大量孔道结构，不及可有效提高透水混凝土的透水系数，同时能提高透水混凝土结构的稳定性，使抗压性能提高，收缩小，抗冻性好。
