为研究矿物掺合料对硫铝酸盐水泥基灌浆料力学性能及流动性能的影响,分别以硅灰、双飞粉、轻质碳酸钙为掺合料制备了硫铝酸盐水泥基灌浆料。在不同水胶比条件下,测试了灌浆料的流动度及不同龄期的抗折、抗压强度。试验结果表明:加入一定量硅灰可以提高灌浆料各龄期强度,但随着硅灰掺量增大,灌浆料流动度降低;加入一定量双飞粉对灌浆料流动度及各龄期强度均有负面影响;加入一定量轻质碳酸钙对灌浆料不同龄期抗压强度有所提高,对流动度及抗折强度没有明显影响。
為研究礦物摻閤料對硫鋁痠鹽水泥基灌漿料力學性能及流動性能的影響,分彆以硅灰、雙飛粉、輕質碳痠鈣為摻閤料製備瞭硫鋁痠鹽水泥基灌漿料。在不同水膠比條件下,測試瞭灌漿料的流動度及不同齡期的抗摺、抗壓彊度。試驗結果錶明:加入一定量硅灰可以提高灌漿料各齡期彊度,但隨著硅灰摻量增大,灌漿料流動度降低;加入一定量雙飛粉對灌漿料流動度及各齡期彊度均有負麵影響;加入一定量輕質碳痠鈣對灌漿料不同齡期抗壓彊度有所提高,對流動度及抗摺彊度沒有明顯影響。

In order to study mineral admixtures' impact on the mechanical and flow properties of sulfur aluminate cement-based grouting material,the author produces sulfur aluminate cement-based grouting material samples by useing silica fume ,Flying powder and light cal-cium carbonate as mineral admixtures.The author also tests and analysises fluidity ,strength index in different water cement ratio. The fl-lowing are the results that we can conclude:(1)adding a certain amount of silica fume can improve the strength of grouting material in each stage,while the grout fluidity will reduce when the dosage of silica fume increases;(2)adding a certain amount of flying powder has negative effects on the grout fluidity and the strength in each stage;(3)adding a certain amount of light calcium carbonate can improve the compressive strength of grout in ecah stage,while has no obvious effects on fluidity and flexural strength.
