Method for adding slag micro-powder into cement and concrete
The invention discloses a method for adding slag micro-powder into cement and concrete, and belongs to the field of preparation of building consumables. The invention discloses a method for adding slag micro-powder into cement. The specific method comprises the following steps of: adopting slag micro-powder with a fineness of 400-450 m<2>/kg to prepare cement with 425 and 425R grades, and adoptingslag micro-powder with a fineness of 400-450 m<2>/kg to prepare cement with 525 and 525R grades. According to the invention, slag micro-powder is used as a concrete admixture to equivalently replace20-70% of cement, so that concrete with high strength, good durability and high performance is prepared; and by adding slag micro-powder into cement and concrete, on the premise that the production quality is guaranteed, the production cost is greatly reduced, the increasingly scarce resources for firing clinker are saved, in addition, the produced cement and concrete have the advantages of beinggood in alkali resistance, high in strength, good in durability and high in performance, the waste circulation efficiency is improved, pollution is reduced, and good market prospects are achieved.
本发明公开一种水泥和混凝土中矿渣微粉的添加方法，属于建筑耗材制备领域，包括一种水泥中矿渣微粉的添加方法，具体方法为采用细度为400～450m/kg的矿渣微粉，用来配制425、425R标号的水泥，采用细度为400～450m/kg的矿渣微粉，用来配制525、525R标号的水泥，一种混凝土中矿渣微粉的添加方法，采用矿渣微粉作为混凝土掺合料，等量取代20％～70％的部分水泥，配制出高强度、耐久性好以及高性能的混凝土，本发明通过向水泥和混凝土中添加矿渣微粉，在保证生产质量的前提下，大大降低了生产成本，节约日益匮乏烧制熟料的资源，此外，生产出的水泥和混凝土，具有耐碱性好、强度高、耐久性好、高性能的优点，有利于提高废弃物循环效率并减少污染，具有良好的市场前景。
