Early-strength, rapid-hardening and high-rheological-property geopolymer grouting material and preparation method thereof
The invention discloses a geopolymer grouting material with early strength, rapid hardening and high rheological property and a preparation method thereof. The geopolymer grouting material is composed of the following components in parts by weight: 283.1 to 353.9 parts of slag, 121.4 to 151.7 parts of fly ash, 0 to 101.1 parts of fluorite powder, 21.2 parts of Na2CO3, 73.2 parts of Na2SiO3, 1200 parts of shaping sand, 6 parts of a retarder, and 252 parts of water, and the shaping sand is prepared by mixing sea sand and machine-made hill sand according to a mass ratio of 1: 3. Industrial waste slag and fly ash are selected as precursors, alkali activators Na2CO3 and Na2SiO3 are added, shaping sand formed by mixing machine-made hill sand and sea sand is used as fine aggregate, the geopolymer cement raw material is prepared through a mechanochemical effect, and the geopolymer cement raw material has the characteristics of proper and controllable setting time, early strength, rapid hardening, high rheological property, excellent durability and the like.
本发明公开了一种早强快硬高流变性能的地聚物灌浆材料及其制备方法。该地聚物灌浆材料由以下重量份数的组分组成：矿渣283.1~353.9份、粉煤灰121.4~151.7份、萤石粉0~101.1份、Na2CO3 21.2份、Na2SiO3 73.2份、整形砂1200份、缓凝剂6份、水252份，其中，所述整形砂由海砂与机制山砂按质量比1:3混合制得。本发明选用工业废料矿渣、粉煤灰为前驱物，加入碱激发剂Na2CO3、Na2SiO3，并使用机制山砂和海砂混合成的整形砂作为细骨料，经机械力化学效应制得所述地聚物水泥原材料，其具有凝结时间合适且可调控、早强快硬、高流变性能、耐久性优等特点。
