Bentonite modified cement and preparation method thereof
The invention relates to bentonite modified cement and preparation thereof; the bentonite modified cement comprises modified cement and a bacterial agent, the preparation of the bentonite modified cement comprises mixing of the modified cement and the bacterial agent, the modified cement comprises bentonite and Portland cement, and the bacterial agent contains bacillus pasteurii. A unique path isfound, bentonite is persistently used for modifying the cement, and enhances the strength of the cement by biomineralization is enhanced; the process parameters are optimized. The bentonite modified reinforced cement provided by the invention has great application value, can ensure reutilization of industrial by-products, also reduces the use amount of cement, and does not produce pollutants.
本发明涉及一种膨润土改性水泥及其制备，所述膨润土改性水泥包含改性水泥和菌剂，所述膨润土改性水泥的制备包括将改性水泥和菌剂混合，所述改性水泥包含膨润土和硅酸盐水泥，所述菌剂中含有巴氏芽孢杆菌。本发明独辟蹊径，坚持使用了膨润土对水泥改性，利用生物矿化增强了水泥的强度；本发明还优化了工艺参数。本发明膨润土改性增强水泥具有很大的应用价值，它可以保证工业副产品的再利用，同时减少水泥的用量，且不会产生污染物。
