Composite anti-seepage material suitable for cold regions and preparation method of composite anti-seepage material
The invention is suitable for the technical field of building materials, and provides a composite anti-seepage material suitable for a cold region and a preparation method thereof, the composite anti-seepage material comprises the following raw materials: fly ash, bentonite, sodium chloride, cement and water, and the raw materials are mixed according to a weight ratio of 30: 1: 3: 2.5: 20. The composite anti-seepage material is prepared from the waste fly ash subjected to hydraulic ash removal, sodium chloride and bentonite, and is low in manufacturing cost, energy-saving and environment-friendly. The composite anti-seepage material is constructed according to the complex hydrogeological conditions of the aquifer, and the anti-seepage capacity change difference caused by the difference of permeability coefficients of different stratums is effectively solved. The composite anti-seepage material has the advantages of being high in strength, low in density, good in impact resistance, fireproof, flame-retardant, high in anti-seepage performance, environmentally friendly, capable of saving energy and the like, can adapt to different temperature and pressure changes of a cold region so as to achieve the anti-seepage function of a polluted site in the cold region, and has great market space and development prospects in the application field of building energy conservation in China.
本发明适用于建筑材料技术领域，提供了一种适用于寒区的复合防渗材料及其制备方法，复合防渗材料包括以下原料：粉煤灰、膨润土、氯化钠、水泥和水，各原料按重量比为30:1:3:2.5:20的比例进行混合。本发明的复合防渗材料利用水力除灰废弃粉煤灰、氯化钠和膨润土配置，造价低廉，节能环保。本发明针对含水层复杂水文地质条件，构建复合防渗材料，有效解决不同地层渗透系数差异导致的防渗能力变化差异。本发明的复合防渗材料具有强度高、密度低、抗冲击性好、防火阻燃、防渗性能高、环保节能等优点，能够适应寒区不同温度和压力变化，以此实现寒区污染场地防渗功能，在我国建筑节能应用领域具有极大的市场空间和发展前景。
