水泥裹砂(石)混凝土,是日本、丹麦等国,在七十年代末和八十年代初,广泛应用的一项新技术。这种技术是先把水泥,砂(石)和部分水放入搅拌机,进行第一次搅拌,使水泥裹在砂(石)上,形成水泥砂(石)浆后,再加入石子和水,进行第二次搅拌,形成混凝土。据国家计委施工局材料,我国水电部等单位,前几年在建筑工程施工中,对水泥裹砂新技术进行了探 Cement sand-clay (stone) concrete is a new technology widely used in Japan, Denmark and other countries in the late 1970s and early 1980s. This technique involves putting cement, sand (stone) and some water into the mixer first, and stirring for the first time, so that the cement is wrapped on the sand (stone) to form cement mortar (stone) slurry, and then stones and water are added. Make a second stir to form the concrete. According to the materials of the State Planning Commission Construction Bureau, China’s Ministry of Water Resources and other units, a few years ago during the construction of the construction project, the new technology of cement sand coating was explored.
