Preparation method of integral hydrophobic slag cement mortar as well as finished product and application of integral hydrophobic slag cement mortar
The invention discloses a preparation method of integral hydrophobic slag cement mortar as well as a finished product and application of the integral hydrophobic slag cement mortar, and belongs to the technical field of cement compositions. Comprising the following steps: (1) dissolving stearic acid in ethanol to obtain a stearic acid solution; dissolving sodium hydroxide in water to obtain an alkali activator; (2) mixing Portland cement and slag to form a cementing material, then adding sand into the cementing material, and mixing to obtain a dry silt material; (3) mixing the stearic acid solution with the silt dry material, adding the alkali activator and water into the obtained mixture, and mixing to obtain modified slag cement mortar; and (4) pouring and hardening the modified slag cement mortar, and curing to complete the preparation of the integral hydrophobic slag cement mortar. The method has the advantages of being convenient to prepare, low in cost, environmentally friendly and non-toxic, and the finished product has low surface energy, a rough porous structure, excellent hydrophobic performance, self-cleaning effect and mechanical durability and wide application prospects.
本发明公开了一种整体疏水矿渣水泥砂浆的制备方法及其成品和应用，属于水泥组合物技术领域。包括如下步骤：(1)将硬脂酸溶于乙醇，得到硬脂酸溶液；将氢氧化钠溶于水，得到碱激发剂；(2)将硅酸盐水泥和矿渣混合形成胶凝材料，随后向其加入砂，混合得到粉砂干料；(3)将所述硬脂酸溶液与所述粉砂干料混合，向所得混合料中加入所述碱激发剂和水，混合得到改性矿渣水泥砂浆；(4)所述改性矿渣水泥砂浆经浇筑，硬化后进行养护，完成整体疏水矿渣水泥砂浆的制备。本方法具有制备方便、成本低、环保无毒的优点，成品具有低表面能和粗糙多孔结构，疏水性能、自清洁效果与机械耐久性优异，应用前景广阔。
