Low-clinker aluminate cementing material for sewage pipeline
The invention provides a low-clinker aluminate cementing material for a sewage pipeline. The low-clinker aluminate cementing material comprises the following raw materials in parts by weight: 3-10 parts of aluminate cement, 60-80 parts of mineral powder, 10-20 parts of fly ash, 5-15 parts of calcium sulfate, 0.5-2 parts of a water reducing agent, 5-10 parts of a compacting agent, 1-3 parts of a shrinkage reducing agent, 0.8-1.2 parts of an anti-cracking agent and 0.02-0.08 part of composite nanofibers. The low-clinker aluminate cementing material, which is obtained by the invention, can effectively realize high sewage corrosion resistance and impermeability under the condition of low aluminate cement clinker dosage, and is beneficial to promoting wider application of the aluminate cementing material in sewage pipeline concrete.
本发明提供一种用于污水管道的低熟料用量铝酸盐胶凝材料，包括以下重量份原料：铝酸盐水泥3～10份、矿粉60～80份、粉煤灰10～20份、硫酸钙5～15份、减水剂0.5～2份、致密剂5～10份、减缩剂1～3份、抗裂剂0.8～1.2份和复合纳米纤维0.02～0.08份；本发明获得的低熟料用量铝酸盐胶凝材料，可有效实现了低铝酸盐水泥熟料的掺量下的高耐污水腐蚀性和抗渗性，有利于促进铝酸盐胶凝材料在污水管道混凝土中的更加广泛的应用。
