Early-strength water reducing agent for fabricated concrete, preparation method and concrete
The invention relates to the technical field of water reducing agents, in particular to an early-strength water reducing agent for fabricated concrete, a preparation method of the early-strength water reducing agent and concrete, and the early-strength water reducing agent comprises the following raw materials in percentage: 3-20% of triethanolamine, 42-50% of mixed sodium salt, 1-5% of methanol, 1-5% of ethanol, 0.5-1% of an air entraining agent, 0.1-1% of a defoaming agent, 1-2% of liquid caustic soda and the balance of water. The sodium salt is prepared by mixing sodium thiocyanate, sodium nitrite and sodium carbonate; the early-strength water reducer has the advantage that the early-strength water reducer has a relatively good early-strength function.
本申请涉及减水剂的技术领域，涉及一种用于装配式混凝土的早强型减水剂及制备方法和混凝土，所述早强型减水剂包括如下百分含量的原料：三乙醇胺3‑20%、混合钠盐42‑50%、甲醇1‑5%、乙醇1‑5%、引气剂0.5‑1%、消泡剂0.1‑1%、液碱1‑2%，余量为水；所述钠盐由硫氰酸钠、亚硝酸钠、碳酸钠混合制得；其具有使减水剂具有较好的早强功能的优点。
