Liquid alkali and chlorine free setting accelerator and preparation method thereof

YANG FUMIN / LIU ZHI / SUN DONGJUAN / SUN CHENGXIAO / HE JUNLI / LIU ZEMIN / YAN JUNJIE / WANG SHUYI

The invention discloses a liquid alkali and chlorine free setting accelerator and a preparation method thereof. The raw materials comprises, by weight, 60-130 parts of aluminum sulfate, 0.5-2 parts of a coagulation accelerator, 0.5-2 parts of a coagulating early strength agent, 0.5-5 parts of an early strength agent, 5-15 parts of a complexing accelerator, 8-20 parts of a stabilizer, 1-5 parts of inorganic acid, 0.25-2 parts of a defoaming agent, and 50-75 parts of water. The prepared liquid alkali and chlorine free setting accelerator solves the problems that alkali and chlorine free setting accelerators in the prior art cannot combine the properties of short initial setting time, short final setting time, high 1 day compressive strength, high 28-day compressive strength rate, and good stability, etc.
