一种赤泥粉煤灰注浆充填材料流变助剂及赤泥粉煤灰注浆充填材料
摘要：
本发明公开了一种赤泥粉煤灰注浆充填材料流变助剂及赤泥粉煤灰注浆充填材料。本发明赤泥粉煤灰注浆充填材料流变助剂，按重量百分数计，包括以下组分：萘系减水剂：25％～50％，引气剂：10％～25％，消泡剂：10％～20％，氧化石墨烯：10％～25％，葡萄糖酸钠：5％～15％。采用本发明赤泥粉煤灰注浆充填材料流变助剂制备的赤泥粉煤灰注浆充填材料出机流动度可提高50％～90％，30min后的流动度可提高60％～120％，且无泌水出现。
摘要（英）：

The invention discloses a rheological additive for a red mud and fly ash grouting filling material and the red mud and fly ash grouting filling material. The rheological additive for the red mud and fly ash grouting filling material is prepared from components in percentage by weight as follows: 25%-50% of a naphthalene water reducer, 10%-25% of an air entraining admixture, 10%-20% of a defoamingagent, 10%-25% of graphene oxide and 5%-15% of sodium gluconate. The red mud and fly ash grouting filling material prepared from the rheological additive for the red mud and fly ash grouting filling material has the fluidity improved by 50%-90% during discharging and the fluidity improved by 60%-120% after 30 min and has no bleeding.
