Concrete anti-seepage and anti-freezing admixture for plateau complex environment and preparation method thereof
The invention discloses a concrete anti-seepage and anti-freezing admixture suitable for a plateau complex environment and a preparation method thereof. The concrete anti-seepage and anti-freezing admixture comprises the following raw materials in percentage by mass: 10-15% of sodium dodecyl benzene sulfonate, 7-10% of calcium nitrite, 3-6% of calcium formate, 5-8% of methanol, 4-7% of ethylene glycol, 2-5% of sodium gluconate, 1-3% of sodium polyacrylate, 11-14% of polyoxyethylene ether and the balance of deionized water. According to the anti-seepage and anti-freezing admixture disclosed by the invention, the construction of concrete under low-temperature and negative-temperature conditions can be realized, the construction period of the concrete can be prolonged, the early strength of the concrete can be improved, and the durability of the concrete and the service capacity of the concrete under complex plateau environment conditions can be effectively improved.
本发明公开了一种适用于高原复杂环境的混凝土防渗抗冻外加剂及其制备方法，以质量分数计，其原材料组成为：十二烷基苯磺酸钠10～15％，亚硝酸钙7～10％，甲酸钙3～6％，甲醇5～8％，乙二醇4～7％，葡萄糖酸钠2～5％，聚丙烯酸钠1～3％，聚氧乙烯醚11～14％，余量为去离子水。本发明的防渗抗冻外加剂，既可以实现混凝土在低温和负温条件下的施工，延长混凝土可施工周期，又可以提高混凝土的早期强度，有效提高混凝土的耐久性和在高原复杂环境条件下的服役能力。
