三十年代以来,混凝土真空工艺经历了初期研究与应用、停顿以及重新采用与深入研究三个阶段。其间,大约有十多年,由于过分注重发展干硬性混凝土,也由于真空工艺与设备还不够完善,致使该工艺的研究与应用几乎陷于停顿。然而,在发展干硬性混凝土的过程中,人们越来越认识到存在成型设备复杂、耗损快,噪声大,能源消耗多以及制品质量往往产生 Since the 1930s, the concrete vacuum process has experienced three stages: initial research and application, pauses, and re-use and in-depth research. In the meantime, about ten years later, due to the excessive emphasis on the development of dry hard concrete, but also because the vacuum process and equipment are still not perfect, the research and application of this process has almost come to a standstill. However, in the process of developing hard and dry concrete, people have increasingly realized that there are complex molding equipment, rapid wear and tear, large noise, high energy consumption, and product quality.
