Water reducer with low slump loss and preparation method of water reducer
The invention discloses a water reducer with low slump loss. The water reducer with low slump loss comprises the following components: acrylic acid, an acrylamide aqueous solution, sulphydryl acetic acid, sodium hydroxide, 2,2-azobis(2-amino bipropylene) hydrochloride and water, wherein the mass concentration of the acrylamide aqueous solution is 50%. The molecular weight of the water reducer disclosed by the invention is 8000-70000, and the added amount of the water reducer is 0.05-1% based on the mass of cement. The water reducer is most suitable for manufacturing cement tubular products.
