水泥基渗透结晶性防水涂料在高原高寒地区大坝工程中的应用

Application of Cement-based Penetrating Crystalline Waterproof Coating in Dam Engineering Under High Altitude and Extremely Cold Climate

水泥基渗透结晶性防水涂料是一种含有活性化合物的粉状防水涂料,广泛应用于地铁、地下室、隧道等多种混凝土结构的内外表面。由于高原高寒地区具有特殊的地理和气候特点,该材料在高原高寒地区的应用效果与其他地方存在明显的不同。结合瓦托水电站现场应用实例,详细介绍了水泥基渗透结晶性防水涂料在高原高寒地区大坝工程中的应用,所取得的经验可为其他类似工程提供参考和借鉴。

Cement-based penetrating crystalline waterproof coating is a powdery waterproof coating containing active compounds.It is widely used in the inner and outer surfaces of various concrete structures such as metro,basement and tunnel project.Due to the special geographical and climatic condition in the area of high altitude and extremely low temperature,the performance of the coating is obviously different from that in other places.This paper,taking into consideration of the field application experience in dam engineering of Watuo Hydropower Station,analyzes the performance of the waterproof coating,and provides reference for other similar projects.
