混凝土真空吸水是一种能改善与提高混凝土物理力学性能以及具有节约水泥、缩短施工养护周期和改善操作条件等优点的混凝土施工工艺。自从60年代末期瑞典开始研究结构简单、能耗低和使用方便的真空吸水机组,并获得成功后,混凝土真空吸水技术的应用才得到了较为迅速的发展。目前瑞典在国际上推广较多和较先进的有 DANAPAC 和 TREMIX 两种机型的真空吸水机组。这两种机型的主要区别在于真空吸水装置(或称为真空脱水卷席),其中前者
Vacuum water absorption of concrete is a kind of concrete construction technology that can improve and improve the physical and mechanical properties of concrete and has the advantages of saving cement, shortening the construction maintenance cycle and improving the operating conditions. Since the end of the 1960s, Sweden began to study vacuum suction units that are simple in structure, low in energy consumption, and easy to use. After successful applications, the application of concrete vacuum absorption technology has been rapidly developed. At present, Sweden has promoted more and more advanced vacuum suction units with DANAPAC and TREMIX models internationally. The main difference between these two models is the vacuum suction device (or vacuum dehydration), the former
