The composition is prepared from 30 to 60 parts of sulfate, 20 to 40 parts of aluminic acid, 10 to 15 parts of organic alcohol amine, 5 to 15 parts of aluminum hydroxide, 2 to 5 parts of diethanol amine, 5 to 8 parts of magnesium fluosilicate, 10 to 50 parts of calcined alunite, 2 to 6 parts of silicon element, 2 to 6 parts of cellulose, 5 to 15 parts of stabilizer, 1 to 5 parts of neutralizer and 10 to 30 parts of solvent. The preparation method comprises the following steps: uniformly stirring hydroxide, diethanol amine, calcined alunite, silicon element, cellulose, a neutralizer and a solvent at a high temperature of 80 DEG C, and reacting at normal temperature for 30 minutes; and adding the mixture obtained in the step S4 into the mixture B, and stirring for 2 hours to obtain the low-alkali accelerator. The cement has the advantages of low mixing amount, good stability, high early strength and high later strength retention rate.
本发明涉及一种用于制备低碱速凝剂的组合物，包括硫酸盐30‑60份、铝酸20‑40份、有机醇胺10‑15份、氢氧化铝5‑15份、二乙醇胺2‑5份、氟硅酸镁5‑8份、煅烧明矾石10‑50份、硅钢素2‑6份、纤维素2‑6份、稳定剂5‑15份、中和剂1‑5份、溶剂10‑30份；将氢氧化、二乙醇胺、煅烧明矾石、硅钢素、纤维素、中和剂、溶剂保持80℃高温搅拌均匀，并在常温下反应30min；将步骤S4加入混合物B内，搅拌2小时，得到所述低碱速凝剂。优点：具有掺量低、稳定性好、早期强度高、后期强度保留率大的特点。
