Concrete environment-friendly early strength agent and preparation method thereof
The concrete environment-friendly early strength agent is prepared from the following raw materials in parts by weight: 20 to 28 parts of sodium thiosulfate, 15 to 22 parts of sodium carbonate, 8 to 12 parts of calcium nitrite, 4 to 6 parts of aluminum salt, 6 to 8 parts of triethanolamine, 5 to 7 parts of sodium acetate, 3 to 4 parts of ethylene glycol, 2.5 to 3.2 parts of cellulose acetate butyrate, 1.4 to 1.8 parts of a silane coupling agent, 1.2 to 1.6 parts of a water reducing agent, 0.2 to 0.4 part of an anti-freezing agent, 0.2 to 0.4 part of an expanding agent, 0.15 to 0.25 part of a thickening agent and 15 to 25 parts of water. According to the environment-friendly early strength agent for the concrete, the raw materials are selected, the content of the raw materials is optimized, and the prepared environment-friendly early strength agent for the concrete can effectively reduce the fluidity of the concrete, shorten the setting time, improve the early strength, improve the cold resistance of the concrete and improve the mechanical property and the corrosion resistance of the cured concrete.
一种混凝土环保早强剂，由包括以下重量份的原料制成：硫代硫酸钠20～28份、碳酸钠15～22份、亚硝酸钙8～12份、铝盐4～6份、三乙醇胺6～8份、乙酸钠5～7份、乙二醇3～4份、醋酸丁酸纤维素2.5～3.2份、硅烷偶联剂1.4～1.8份、减水剂1.2～1.6份、防冻剂0.2～0.4份、膨胀剂0.2～0.4份、增稠剂0.15～0.25份、水15～25份。本发明的混凝土环保早强剂通过精选原料组成，并优化各原料含量，制得的混凝土环保早强剂可有效减小混凝土的流动性，缩短凝结时间，提高早期强度，提升混凝土的耐寒性能，提升固化后混凝土的力学性能和耐腐蚀性能。
