The invention provides a machine-made sand viscosity reducer for concrete and a preparation method and application thereof, the machine-made sand viscosity reducer for concrete comprises sepiolite powder, a polymer emulsifier, cellulose and inorganic salt, the synthesis process is simple, and the machine-made sand viscosity reducer for concrete is a combination of polyethylene glycol, carbamide, welan gum, sodium hydroxide, diethanolisopropanolamine, dipropylene glycol dimethyl ether and polyol. The machine-made sand viscosity reducer for concrete can be synthesized at normal temperature, so that the energy consumption is low, and the raw materials are easy to obtain, harmless, green, environment-friendly and suitable for industrial production; meanwhile, the machine-made sand viscosity reducer for the concrete can solve the problems of poor concrete state and the like caused by machine-made sand fault gradation, and the wrapping property and the pumping property of the concrete can be effectively improved. 本
