Cold-resistant and salt-resistant concrete admixture as well as preparation method and application thereof
The invention provides a cold-resistant and salt-resistant concrete admixture as well as a preparation method and application thereof, and belongs to the technical field of buildings and civil engineering. The concrete admixture comprises a water reducing agent, an anti-freezing agent, calcium carbonate, polyvinyl alcohol, modified nano montmorillonite and a coupling agent, wherein the anti-freezing agent is diethylene glycol butyl ether acetate, hexaethyl phosphoramidite and copper 2-ethylhexanoate. By compounding the components, the compactness of the concrete is effectively improved, so that the concrete provided by the invention has better cold resistance, freezing resistance, impermeability and salt corrosion resistance, and the strength of the concrete can be improved.
本发明提供了一种抗寒抗盐混凝土外加剂及其制备方法和应用，属于建筑与土木工程技术领域。本发明的混凝土外加剂包括减水剂、防冻剂、碳酸钙、聚乙烯醇、改性纳米蒙脱石和偶联剂，其中防冻剂为二乙二醇丁醚醋酸酯、六乙基亚磷酰三胺和2‑乙基己酸铜。通过各组分的复配使用，有效提高了混凝土的致密性，使得本发明提供的混凝土同时具有较好的抗寒抗冻性、抗渗性和抗盐侵蚀性能，还可改善混凝土的强度。
