Preparation method of compression-resistant and waterproof foam cement
The invention relates to the technical field of preparation of building materials, and concretely relates to a preparation method of compression-resistant and waterproof foam cement. High temperatureand an alkaline solution can promote silicon-oxygen bonds and aluminum-oxygen bonds of kaolin to be broken, oligomeric tetrahedron units gradually react along with the proceeding of a reaction and arepolymerized afresh in order to form a network-shaped silicon-aluminum-oxygen compound, pores in transparent concrete are effectively filled with the silicon-aluminum-oxygen compound to make the transparent concrete structure densified and facilitate improvement of the waterproofness of the foam cement, and normal-temperature closed moisturizing maintenance is an appropriate maintenance mode of the foam cement, so the foam cement has good mechanical properties, the compressive strength of the foam cement is further improved, and the foam cement has wide application prospects.
本发明涉及建筑材料制备技术领域，具体涉及一种抗压防水型发泡水泥的制备方法。本发明利用高岭土在高温和碱溶液的作用下，促使高岭土的硅氧键和铝氧键断裂，这些低聚态四面体单元随着反应的进行，逐渐脱水重新聚合，形成网络状硅铝氧化合物，将硅铝氧化合物有效填充在透明混凝土内部孔隙中，使得透明混凝土结构致密化，有利于发泡水泥的防水性得到提高，常温密闭保湿养护是发泡水泥合适的养护方式，从而表现出良好的力学性能，进一步提高发泡水泥的抗压强度，具有广泛的应用前景。
