清水混凝土技术在水电站厂房中的应用研究

Application of Fair-faced Concrete Technology in Hydropower Plant

近年,清水混凝土在水电站厂房中逐步得到推广应用。水电站厂房因机械、电气设备较多,导致厂房异型结构多种多样。阐述了对清水混凝土技术在水电站厂房中的应用研究过程。开仓前,严格控制骨料质量。胶凝材料采用同一厂家,严格控制色泽,模板拼缝处和阴阳角模连接处贴高密度海绵密封条以防漏浆,脱模剂采用水性脱模剂,模板采用木胶合板和异型钢模板以达到清水混凝土效果。

In recent years,the application of fair-faced concrete in hydropower plants is gradually popularized.Due to the large number of mechanical and electrical equipment in the powerhouse of hydropower plants,the special-shaped structures in the powerhouse are various.Before opening the warehouse,the quality of aggregates is strictly controlled.The cementitious materials must be from the same manufacturer.The color and luster are also strictly controlled.High-density sponge seals are attached to the joints of the formwork and the connection of the yin and yang angle forms to prevent leakage of the slurry.The release agent is water-based,and the formwork is made of plywood and special-shaped steel formwork to achieve the effect of fair-faced concrete.
