Sleeve grouting material with long fluidity retention time
The invention discloses a sleeve grouting material with long fluidity retention time efficiency. The sleeve grouting material comprises the following components in parts by weight: 40-45 parts of machine-made sand, 40-45 parts of a cementing material, 4-6 parts of silica fume, 4-6 parts of a mineral admixture and 4-6 parts of a compound functional agent, the compound functional agent is prepared from the following components in parts by weight: 0.2 to 0.4 part of polycarboxylic acid-based water reducing agent, 0.2 to 0.4 part of polyether type defoaming agent, 1.5 to 2 parts of sulphoaluminate expansive cement, 1.5 to 2.5 parts of quicklime powder and 0.5 to 1 part of magnesium oxide powder. Different action mechanisms of all the materials in a sleeve grouting material system are adjusted through reasonable proportioning, the long fluidity retention time of a product as long as 3 hours or above and excellent comprehensive performance are achieved, and the sleeve grouting material is free of segregation and bleeding and high in strength.
本发明公开了一种长流动度保持时效套筒灌浆料，包括如下重量份数的组分：机制砂40～45份、胶凝材料40～45份、硅灰4～6份、矿物掺合料4～6份、复配功能剂4～6份；复配功能剂由如下重量份数的组分组成：聚羧酸基减水剂0.2～0.4份、聚醚型消泡剂0.2～0.4份、硫铝酸盐膨胀水泥1.5～2份、生石灰粉1.5～2.5份、氧化镁粉0.5～1份。本发明通过合理配比来调节套筒灌浆料体系中各个材料不同作用机理，达到产品长达3小时以上的长流动度保持时效和极佳的综合性能，不离析，无泌水，高强度。
