Composite cement, cement prefabricated part and preparation method and application of cement prefabricated part
The invention discloses composite cement, a cement prefabricated part and a preparation method and application of the cement prefabricated part. The composite cement is prepared from inert powder particles and cement clinker particles, wherein the particle size of the inert powder particles is larger than that of the cement clinker particles, and the mass fraction of the inert powder particles in the composite cement is 35%-75%. In the composite cement disclosed by the invention, inert powder (limestone powder or quartz powder) is selected as a framework of the composite cement, and the resource source is wide. Due to the addition of the inert powder, the use amount of the cement is reduced, the cost is saved, and the emission of carbon dioxide is effectively reduced.
本发明公开了一种复合水泥、水泥预制件及其制备方法与应用，该复合水泥的制备原料为惰性粉体颗粒和水泥熟料颗粒；其中，所述惰性粉体颗粒粒径大于所述水泥熟料颗粒粒径，且所述复合水泥中惰性粉体颗粒的质量分数为35％～75％。本发明的复合水泥中选用惰性粉体(石灰石粉或石英粉)作为复合水泥的骨架，其资源来源广泛。惰性粉体的添加，降低了水泥的用量，有利于节约成本且有效的降低了二氧化碳的排放。
