混凝土真空吸水工艺是提高工程质量、加快施工进度的一种先进工艺。它是在浇灌、振捣、抹平后的混凝土表面铺上吸垫,启动真空设备,从混凝土中吸出游离水,以降低混凝土水灰比的一种方法。经过近几年的施工实践,这个工艺已日趋成熟,广泛用于道路及大面积工业厂房地坪的施工,并推广到机场、港口、大坝、厂房等方面。现在将施工工艺简要介绍如下: Concrete vacuum suction technology is an advanced technology that improves the quality of the project and speeds up the construction progress. It is a way to reduce the water-cement ratio of concrete by placing a suction pad on the surface of the concrete after pouring, vibrating and smoothing, and starting the vacuum equipment to suck out free water from the concrete. After construction practice in recent years, this process has gradually matured and is widely used in the construction of roads and floors of large-scale industrial plants, and has been extended to airports, ports, dams, and factories. Now briefly describe the construction process as follows:
