Self-repairing super-sulfur cement and preparation method thereof

The invention belongs to the technical field of geotechnical materials, and relates to self-repairing super-sulfur cement and a preparation method thereof. The self-repairing super-sulfur cement comprises the following components in percentage by weight: 75%-85% of slag, 10%-20% of biologically modified phosphogypsum and 1%-5% of an alkaline component. The industrial byproduct ardealite is pretreated for biological modification, the ardealite is used as a microbial remediation agent raw material for preparing the super-sulfur cement, and the super-sulfur cement has good self-remediation capability and compressive strength. 本发明属于土工材料技术领域，涉及一种自修复超硫水泥及其制备方法。一种自修复超硫水泥，包括以下重量百分比的组分：矿渣75％-85％、生物改性磷石膏10％-20％和碱性成分1％-5％。利用工业副产磷石膏，并对其预处理进行生物改性，作为微生物修复剂原料用于制备超硫水泥，该超硫水泥具有良好自修复能力和抗压强度。
