Low-clinker-dosage sulfoaluminate cementing material for sewage pipeline
The invention discloses a low-clinker-dosage sulfoaluminate cementing material for a sewage pipeline. The low-clinker-dosage sulfoaluminate cementing material comprises the following raw materials in parts by weight: 3-10 parts of sulfoaluminate cement, 30-80 parts of mineral powder, 5-17 parts of calcium sulfate, 0.5-2 parts of a water reducing agent, 3-10 parts of a densifying agent, 1-3 parts of a shrinkage reducing agent, 0.5-1.2 parts of an anti-cracking agent, 0.02-0.10 part of nano fibers, and 0.5-2 parts of basalt fibers. When the product is aged for 12 months, the corrosion resistance coefficient is 1.16 or above, the compression-bending ratio is 2.15-3.22, and the corrosion resistance and the crack resistance are good; the cementing material disclosed by the invention has long-term corrosion resistance, the using amount of sulfoaluminate cement clinker and mineral powder are relatively low, the cost is low, and the cementing material is easy to popularize and use.
本发明公开一种用于污水管道的低熟料用量硫铝酸盐胶凝材料，包括以下重量份原料：硫铝酸盐水泥3～10份、矿粉30～80份、硫酸钙5～17份、减水剂0.5～2份、致密剂3～10份、减缩剂1～3份、抗裂剂0.5～1.2份、纳米纤维0.02～0.10份、玄武岩纤维0.5～2份。本发明产品龄期12个月时抗蚀系数1.16以上，压折比2.15～3.22，抗腐蚀性能、抗裂性能良好；本发明胶凝材料具有长期抵抗腐蚀性能，且硫铝酸盐水泥熟料和矿粉用量较低，成本低，易于推广使用。
