Method for preparing cement admixture from diatomite and bauxite and application of cement admixture
The invention relates to a method for preparing a cement admixture by using diatomite and bauxite and application of the cement admixture, and belongs to the technical field of cement. According to the method for preparing the cement admixture from the diatomite and the bauxite and the application, the utilization rate of low-grade diatomite and bauxite waste residues is increased, the cement production cost is reduced, and meanwhile carbon emission in the cement production process is reduced. The method comprises the following steps: uniformly mixing activated diatomite powder and bauxite powder to obtain the cement admixture, and applying the cement admixture in cement mortar. According to the invention, the cement admixture prepared from diatomite and bauxite can replace cement with the mass fraction of 30%, and the flexural activity index of a cement mortar test piece is 84-140% of that of standard cement mortar in 28d; the compressive activity index is 61%-123% of that of standard cement mortar. According to the invention, the cement admixture can be obtained.
一种利用硅藻土和铝矾土制备水泥混合材的方法和应用，它属于水泥技术领域。本发明提供了一种利用硅藻土和铝矾土制备水泥混合材的方法和应用，提高了低品位硅藻土和铝矾土废渣的利用率，降低了水泥生产成本，同时减少了水泥生产过程的碳排放。方法：将活化硅藻土粉料和铝矾土粉料混合均匀，得到水泥混合材，水泥混合材在水泥胶砂中应用。本发明利用硅藻土和铝矾土制备水泥混合材可代替质量分数为30％水泥，28d时水泥胶砂试件的抗折活性指数为标准水泥胶砂的84％～140％；抗压活性指数为标准水泥胶砂的61％～123％。本发明可获得水泥混合材。
