Premixed shield grouting material and preparation method thereof
The invention relates to a premixed shield grouting material and a preparation method thereof. The premixed shield grouting material is prepared from the following raw materials in parts by weight: 70 to 80 parts of fly ash, 100 to 120 parts of superfine powder, 120 to 130 parts of cement, 593 to 675 parts of stone powder, 15 to 20 parts of desulfurized gypsum and 0.5 to 1 part of water reducing agent. The premixed shield grouting material is scientific and reasonable in proportion and does not contain common accelerator, bentonite, water reducing agent and lithium carbonate, the performance indexes such as fluidity, apparent setting time, initial setting time, consolidation rate and compressive strength can still meet the standard requirements while the cost is reduced, and the market is greatly expanded; the preparation method is simple and reasonable in process, easy to control in operation and beneficial to large-scale production.
本发明涉及一种预拌盾构注浆料及其制备方法。所述预拌盾构注浆料包括如下重量份的原料：粉煤灰70～80份，超细粉100～120份，水泥120～130份，石粉593～675份，脱硫石膏15～20份，减水剂0.5～1份。所述预拌盾构注浆料配比科学合理，并且不含有常用的速凝剂、膨润土、减水剂和碳酸锂，在降低成本的同时，流动度、表观凝结时间、初凝时间、固结率和抗压强度等性能指标仍可满足标准要求，大大拓展了市场；所述的制备方法，工艺简单合理，操作易控，有利于规模化产出。
