Method for preparing limestone calcined clay cement from halloysite
The invention discloses a method for preparing limestone calcined clay cement from halloysite. The limestone calcined clay cement (called calcined clay cement for short) is prepared by mixing calcined halloysite, limestone, gypsum and ordinary Portland cement or cement clinker according to a certain proportion. The calcined clay cement material prepared by the invention has excellent mechanical properties and durability, can replace ordinary Portland cement for use, and can greatly reduce energy consumption and carbon emission in the cement industry. In addition, the fired clay cement prepared by the invention is simple in process and low in cost, so that the fired clay cement has a wide application prospect.
本发明公开了一种利用埃洛石制备石灰石煅烧粘土水泥的方法。所述的石灰石煅烧粘土水泥(Limestone calcined clay cement，简称烧粘土水泥)是通过煅烧埃洛石、石灰石、石膏及普通硅酸盐水泥或水泥熟料以一定的比例混合制备而成。本发明所制备的烧粘土水泥材料具有优良的力学性能和耐久性，可以替代普通硅酸盐水泥使用，能大幅降低水泥行业的能耗与碳排放。此外，本发明制备的烧粘土水泥工艺简单、成本低廉，因而具有广阔的应用前景。
