High-strength and water-resistant phosphogypsum-based composite cementing material and preparation method thereof
The invention discloses a high-strength and water-resistant phosphogypsum-based composite cementing material and a preparation method thereof. The high-strength and water-resistant phosphogypsum-basedcomposite cementing material is prepared from the following raw materials in parts by weight: 88-99 parts of phosphogypsum, 1-12 parts of ash calcium powder, 4-15 parts of cement, 0.1-1 part of a water reducing agent and 0.1-1 part of a retarder. According to the invention, the production energy consumption of the phosphogypsum-based cementing material is reduced, the strength and the water resistance of the phosphogypsum-based cementing material are improved, the cost is low, resources are saved, and the comprehensive utilization rate of phosphogypsum is increased.
本发明公开了一种强度高、耐水磷石膏基复合胶凝材料及制备方法。按重量份计，是以下述原料制得：磷石膏：88～99份、灰钙粉：1～12份、水泥：4～15份、减水剂：0.1～1份、缓凝剂：0.1～1份。本发明具有降低磷石膏基胶凝材料的生产耗能，提高其强度及耐水性，成本低，节约资源，增加磷石膏的综合利用率的特点。
