混凝土真空吸水工艺自从本世纪三十年代在美国创始以来,受到欧、美、日等发达国家的重视,一度在水工、机场、公路以至房屋建筑等工程中采用,使混凝土强度等性能得到显著改善。五十年代我国也曾应用于大坝溢流面和厂房楼地板施工。但是由于工艺和设备均未完善,在成本、节能和工效等方面出现不少缺点,以致发展停滞。七十年代初瑞典开始采用塑料网真空腔可卷气垫,代替原来的刚性真空吸垫,在施工效率、节能省时、降低造价等方面得到显著改进,使这一工艺重新得到活力,十多年来发展迅 Since its founding in the United States in the 1930s, the vacuum water absorption technology of concrete has attracted the attention of developed countries such as Europe, the United States, and Japan. It was once adopted in hydraulic engineering, airports, highways, and even housing construction, making concrete strength and other properties significantly improved. improve. In the fifties, China had also used the dam overflow surface and the floor of the factory building. However, due to the imperfect process and equipment, there are many shortcomings in cost, energy saving and ergonomics, which led to the stagnation of development. In the early 1970s, Sweden began to use plastic net vacuum chambers to roll up air cushions instead of rigid vacuum suction pads. It has achieved significant improvement in terms of construction efficiency, energy saving, and cost reduction, which has revived this process for more than a decade. To develop
