NOVELTY - Fly ash-containing graphene oxide concrete comprises 314.5 pts. wt. cement, 166 pts. wt. water, 652 pts. wt. natural river sand, 1210 pts. wt. crushed stone, 55.5 pts. wt. coal ash powder, 7.4 pts. wt. polycarboxylate superplasticizer, 13.875 pts. wt. graphene oxide solution raw material, where graphene oxide nanosheet solid content in the graphene oxide solution raw material is 1.6%, and thickness of graphene oxide nanosheet is 1 to 2 nanometer, the chip diameter is 10 mu m, purity is more than 99%, and surface of the graphene oxide nanosheet has a large amount of oxygen-containing groups, has good hydrophilicity, and is non-conductive. USE - Fly ash-containing graphene oxide concrete. ADVANTAGE - The fly ash-containing graphene oxide concrete is simple and easy to operate, has high intensity and performance, reduced the dosage of cement, and protects environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphite oxide concrete filled with fly ash, which involves: (A) adding 7.4 pts. wt. polycarboxylic acid high performance water reducing agent to 166 pts. wt. water, and uniformly stirring for 90 seconds to obtain first solution; (B) adding 13.875 pts. wt. graphene oxide solution raw material to first solution, stirring uniformly for 90 s to obtain second solution; (C) adding 314.5 pts. wt. cement and 55.5 pts. wt. pulverized coal ash, 652 pts. wt. natural river sand and second solution to the mixer, and uniformly stirring for 120 s at a speed of 2.5 m/s; (D) adding 1210 pts. wt. gravel at a speed of 1.5 m/s, uniformly stirring for 150s, discharging, the prepared graphene oxide concrete mixture; (E) pouring the graphene oxide mortar mixture into the mold, filling twice, filling the mold each time half; and (F) placing on the vibrating table to be tapped, and stirring for 60 times each time to avoid over-vibration under oxygen protection.
