Abstract

The invention discloses a high-efficiency water-reducing agent, which is prepared by the following raw materials in parts by weight: 50-60 parts of beta-naphthalene sulfonate formaldehyde condensate, 20-30 parts of poly(ethylene glycol) monomethyl ether methacrylate, 15-25 parts of calcium lignosulphonate, 10-15 parts of ethylene oxide-propylene oxide copolymer, 2-4 parts of trehalose, 1.5-2.5 parts of silicone powder, 4-8 parts of shale ashes, 2.5-4.5 parts of sodium hydrogen sulfite, 5-10 parts of polyethylene oxide, 8-14 parts of aluminum tripolyphosphate, 2-3 parts of cocoanut oil diethanolamide, 1-2 parts of barium dinonyl naphthalenesulfonate, 2-3 parts of urotropine, and 3-5 parts of auxiliaries. The water-reducing agent is high in water-reducing rate, good in flowability, capable of obviously improving the flowability and working degree of the concrete, obvious in early-strength effect after being finally set, capable of greatly improving the strength of the concrete in all ages, and applicable to various concretes.

Description

technical field [0001] The invention relates to a high-efficiency water reducer, which belongs to the field of concrete admixtures. Background technique [0002] Concrete admixtures, referred to as admixtures for short, refer to substances that are added to improve the performance of concrete before or during the mixing of concrete. Because admixtures can effectively improve the performance of concrete and have good economic benefits, they have been widely used in many countries, and their application in engineering has attracted more and more attention, becoming an indispensable material in concrete. Among them, the water reducer is the most important admixture in concrete. It can reduce the mixing water consumption and improve the concrete strength under the condition that the workability of concrete and the amount of cement remain unchanged; or under the condition that the workability and strength remain unchanged. Next, save the amount of cement. However, the water red...
