High-flow-state filling mortar containing large-volume fly ash and preparation method of high-flow-state filling mortar
The invention discloses high-flow-state filling mortar with large-volume fly ash and a preparation method of the high-flow-state filling mortar. The high-flow-state filling mortar is prepared from the following components in parts by weight: 425-595 parts of fly ash, 170-250 parts of Portland cement, 17-40 parts of quick lime, 200-280 parts of sand, 100 parts of water, 5-10 parts of naphthalene sulfonate formaldehyde condensate, 3-7 parts of triethanolamine, 1-5 parts of polyacrylamide, 2-3 parts of calcium formate and 2-3 parts of ethylene diamine tetraacetic acid. The setting time can be shortened, the hydration heat is reduced, the influence of the sand mud content on the mortar performance is greatly reduced, and the mortar filling requirement of underground engineering construction is met.
本发明公开了一种大掺量粉煤灰高流态充填砂浆及其制备方法，由以下重量份的组分组成：粉煤灰425‑595份，硅酸盐水泥170‑250份，生石灰17‑40份，砂200‑280份，水100份，萘磺酸盐甲醛缩合物5‑10份，三乙醇胺3‑7份，聚丙烯酰胺1‑5份，甲酸钙2‑3份，乙二胺四乙酸二钠2‑3份。能够实现缩短凝结时间、减少水化热和大幅度降低砂含泥量对于砂浆性能的影响，满足地下工程施工砂浆充填需求。
