混凝土真空吸水技术最初是由德国人提出的,30年代首先由美国人取得技术专利权,后来逐步在欧、美各国应用。50年代我国曾一度在水工建筑上开始使用。当时由于设备条件等因素的影响,未能得以推广。近年来,混凝土真空吸水技术无论是在理论研究与应用技术方面,还是在设备条件方面,都有了较大的进展,于是,推广应用也 The vacuum suction technology for concrete was originally proposed by the Germans. In the 1930s, Americans first obtained the patent right for the technology, and gradually applied it in various countries in Europe and the United States. In the 1950s, China was once used in hydraulic construction. At that time, due to factors such as equipment conditions, it could not be promoted. In recent years, concrete vacuum suction technology has made great progress both in theoretical research and application technology and in terms of equipment conditions. Therefore, the promotion and application of
