低温混凝土早强剂
摘要：
本发明涉及一种低温混凝土早强剂，属于水泥外掺剂。由偏铝酸钠，硅酸钠，硫酸钠，碳酸钠，碳酸锂，溴化锂，碱金属氯化物，碱金属氢氧化物，氟硅酸锌，氟硅酸镁，氟硅酸钠，氟化钙，三异丙醇胺，降失水剂，β-萘磺酸甲醛缩聚物，超细粉末SiO2，超细粉末Al2O3，超细粉末Fe2O3，超细粉末CaO，超细粉末MgO所构成；本发明主要应用于冬季混凝土施工或低温环境应急工程；使用时把本发明的组合混合物按水泥重量的2～5％掺入混泥土后拌水，搅拌；可在环境温度在近似4℃的低温环境下12小时形成水泥块的13.5MPa强度，24小时达到18.5MPa，三天水泥块强度达到30MPa的高强度。
摘要（英）：

The invention relates to a low-temperature concrete early strength agent, which belongs to cement additives. The early strength agent consists of sodium metaaluminate, sodium silicate, sodium sulfate, sodium carbonate, lithium carbonate, lithium bromide, alkali metal chlorides, alkali metal hydroxides, zinc fluosilicate, magnesium fluosilicate, sodium fluosilicate, calcium fluoride, triisopropanolamine, a filtrate reducer, beta-naphthalene formaldehyde sulfonate polycondensate, ultrafine powder SiO2, ultrafine powder Al2O3, ultrafine powder Fe2O3, ultrafine powder CaO and ultrafine powder MgO. The early strength agent is mainly applied to winter concrete construction or low-temperature environmental emergency projects; when the early strength agent is used, the composition mixture is added into concrete according to 2 to 5 percent of the total weight of cement, water is added and then stirring is performed; and a cement block with the strength of 13.5MPa can be formed in a low-temperature environment at the ambient temperature of approximately 4 DEG C within 12 hours, a cement block with the strength of 18.5MPa can be formed within 24 hours and a cement block with the high strength of 30MPa can be formed within three days.
