一、概述混凝土真空吸水工艺系借助真空设备对新鲜混凝土进行机械脱水处理的新工艺。采用该工艺可相应配制流动性大的混凝土;施工方便;劳动强度减轻;经过真空脱水,大大降低了成型混凝土的最终水灰比,从而增加了混凝土的密实性,改善和提高了混凝土的物理力学性能。因此,该工艺被列为国外七十年代混凝土施工四项新技术之一。 First, an overview of the concrete vacuum suction system with vacuum equipment for fresh concrete mechanical dehydration of the new technology. The process can be used to prepare the concrete with high fluidity; the construction is convenient; the labor intensity is reduced; the final water-cement ratio of the shaped concrete is greatly reduced through the vacuum dehydration, thereby increasing the compactness of the concrete and improving and enhancing the physical mechanics of the concrete performance. Therefore, the process is listed as one of the four new technologies for concrete construction abroad in the seventies.
