Flow state filling material and preparation method thereof
The invention discloses a flow-state filling material and a preparation method thereof, and the flow-state filling material comprises the following raw material components in parts by weight: 80-95 parts of argillaceous siltstone shield muck by dry weight, 5-20 parts of regenerated micro powder, 3-20 parts of granulated blast furnace slag, 1-10 parts of fly ash, 1-10 parts of cement clinker, 0.2-2 parts of industrial byproduct gypsum, 0.5-2 parts of silica fume, 1-6 parts of tung oil, 0.1-0.4 part of cellulose ether and 0.1-0.7 part of a water reducing agent. The flow-state filling material not only realizes high-dosage resource utilization of solid wastes such as the argillaceous siltstone shield muck and the regenerated micro powder, but also has the advantages of good fluidity, low bleeding rate, short setting time, high early strength, low shrinkage rate and difficulty in cracking.
本发明公开了一种流态填充材料及其制备方法，流态填充材料包括以下重量份的原料组分：泥质粉砂岩盾构渣土以干重计80～95份，再生微粉5～20份，粒化高炉矿渣3～20份，粉煤灰1～10份，水泥熟料1～10份，工业副产石膏0.2～2份，硅灰0.5‑2份，桐油1‑6份，纤维素醚0.1～0.4份，减水剂0.1～0.7份，分散剂0.1～0.7，激发剂0.5～2份，所述流态填充材料不仅实现了泥质粉砂岩盾构渣土、再生微粉等固废高掺量资源化利用，还具有流动性好、泌水率低、凝结时间短、早期强度高、收缩率低、不易开裂的优点。
