NOVELTY - Preparing mud-resistant concrete water-reducing agent comprises (i) taking 180-200 pts. wt. methyl alkenyl polyoxyethylene ether, 7-9 pts. wt. sodium styrene sulfonate and 100-120 pts. wt. water and mixing, heating to 40-55degrees Celsius, and stirring for 30-40 minutes to dissolve to obtain a mixed solution; (ii) adding 60-90 pts. wt. graphene oxide solution and 8-13 pts. wt. acrylamide into the mixed solution, stirring and mixing for 20-30 minutes, adding 5-8 pts. wt. oxidizing agent, reacting for 30-35 minutes, adding 10-12 pts. wt. reducing agent to react for 30-60 minutes, and heat preserving the mixed solution at 55-60degrees Celsius for 6-8 hours; and (iii) adding acrylic acid into the insulated solution, mixing for 30-40 minutes, adding 28-30 wt.% sodium hydroxide aqueous solution to adjust the pH to 6-7 and cooling to 20-25degrees Celsius. USE - The method is useful for preparing mud-resistant concrete water-reducing agent. ADVANTAGE - The agent effectively reduces the viscosity of the cement slurry body, reaches the effect of blocking mud, and improves the slump retaining performance of the concrete, which is good for improving the compressive property of the concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for water-reducing agent prepared by the above mentioned method.
