在我国,随着建筑业的发展,混凝土外加剂的用量也不断增加,特别是在混凝土的冬期施工中,由于电热法、暖棚法、蓄热法等费用昂贵,而采用掺混凝土防冻外加剂的施工方法不但能使建筑工程的造价大大降低,而且使用方便,由于混凝土防冻外加剂已在混凝土冬期施工中获得日益广泛的应用,因此许多地方已把它作为混凝土冬期施工中除水泥、砂、石、水以外不可缺少的第五种材料。对节约能源的重视进一步促进了混凝土防冻外加剂的发展。一些国家(如苏联、东欧等国家)几乎全部冬期施工的建筑工程中均掺有混凝土防冻外加剂,其它国家在混凝土冬期施工中采用掺混凝土防冻外
In China, with the development of the construction industry, the amount of concrete admixtures is also increasing. Especially in the winter construction of concrete, due to the high cost of the electric heating method, the warm greenhouse method and the thermal storage method, the admixture of concrete with antifreeze admixture is used. The construction method not only can greatly reduce the construction cost of the construction project, but also is convenient to use. Because the concrete antifreeze admixture has been widely used in the winter construction of concrete, it has been used as a concrete in winter construction in addition to cement, sand, Indispensable fifth material besides stone and water. The emphasis on energy conservation further promotes the development of concrete antifreeze admixtures. Almost all countries (such as the Soviet Union, Eastern Europe, etc.) have incorporated concrete antifreeze admixtures in almost all winter construction projects. Other countries use concrete-freed antifreeze in winter concrete construction.
