High-strength grouting material co-doped with superfine fly ash alkali-activated geopolymer and preparation method thereof
The invention discloses a high-strength grouting material co-doped with a superfine fly ash alkali-activated geopolymer and a preparation method of the high-strength grouting material. The high-strength grouting material is prepared from 210 to 230 parts of cement, 60 to 80 parts of superfine fly ash, 90 to 100 parts of mineral powder, 130 to 140 parts of water, 740 to 750 parts of quartz sand and 5 to 6 parts of an additive, the additive comprises an alkali activator and a water reducing agent, and the alkali activator additive is a sodium hydroxide alkaline additive; the preparation method of the high-strength grouting material comprises the following steps: step 1, weighing the raw material components in parts by weight, and hanging slurry in a horizontal stirrer; step 2, adding the weighed cement, superfine fly ash, mineral powder and quartz sand into a stirrer, and carrying out dry mixing for 2-4 minutes; and step 3, uniformly mixing the dry materials, pouring the water reducing agent and the mixing water, and continuously stirring for 3-5 minutes until the mixture is in a flow state, thereby obtaining the high-strength grouting material slurry. The high-strength grouting material has the advantages of simple preparation process, low labor cost, low carbon and environmental protection in production, and can greatly improve the utilization efficiency of solid waste resources when being applied to the high-strength grouting material.
本发明公开了一种复掺超细飞灰碱激发地聚合物的高强灌浆料及制备方法，包括：210‑230份的水泥、超细飞灰60‑80份、90‑100份的矿粉、130‑140份的水、740‑750份的石英砂、5‑6份的外加剂；所述外加剂包括碱激发剂与减水剂，所述碱激发外加剂为氢氧化钠类碱性添加剂；高强灌浆料制备方法包括以下步骤：步骤一、按照重量份数称取各原料组分，卧式搅拌机挂浆；步骤二、将称好的水泥、超细飞灰、矿粉、石英砂加入搅拌机，干拌2‑4min；步骤三、干料混合均匀后，倒入减水剂和拌合水，继续搅拌3‑5min，至流态即可得到高强灌浆料浆体。根据本发明，具备制备工艺简单、工成本低、生产低碳环保的优点，应用到高强灌浆料中能大幅提高固废资源的利用效率。
