混凝土真空脱水施工就是用真空装置将混凝土拌合物中多余的水吸出,从而达到降低水灰比、增加密实度、提高混凝土强度(特别是早期强度)和改善混凝土其它物理力学性能的目的。实践证明,这种施工方法既可以节约水泥,又可加 Concrete vacuum dewatering construction is to use vacuum device to suck excess water from concrete mixture to achieve the purpose of reducing water-cement ratio, increasing density, increasing concrete strength (especially early strength) and improving other physical and mechanical properties of concrete. Practice has proved that this method of construction can not only save cement, but also add
