一、概述所谓振动-真空混凝土成型法,就是在混凝土构件或结构的成型过程中,采用振动设备使混凝土拌合物充模,并得到初步密实,再采用真空设备从混凝土中排出一部分水,以降低混凝土的水灰比,使混凝土密实,从而提高混凝土强度(特别是早期强度),并改善混凝土的其他物理力学性能的一种方法。 I. Overview The so-called vibration-vacuum concrete forming method is the use of vibration equipment in the molding process of concrete components or structures to fill the concrete mix and obtain a preliminary compaction, and then use the vacuum equipment to discharge a part of the water from the concrete. A method of reducing the water-cement ratio of concrete to make concrete dense, thereby improving concrete strength (especially early strength), and improving other physical and mechanical properties of concrete.
