▎ 摘  要

NOVELTY - Graphene oxide reinforced geopolymer comprises 100 pts. wt. silicon-aluminium raw material, 50-85 pts. wt. alkali excitant, 0.01-0.07 pts. wt. oxidized graphene and 0.02-0.20 pts. wt. dispersant. The aluminum raw material is selected from any one or the mixture of more than two ofany proportion from metakaolin, coal gangue, flyash or slag. USE - Graphene oxide reinforced geopolymer. ADVANTAGE - The graphene oxide reinforced geopolymer is eco-friendly and cost-effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide reinforced geopolymer, which involves: (A) adding graphene oxide and dispersant to the alkali activator, where after mechanical stirring for 10-20min; (B) carrying out ultrasonic dispersion for 30-60min to obtain suspension; (C) adding into thesuspension aluminum raw material; (D) stirring for 1-3min with the e rotating speed of 10-50r/min; (E) stirring for 1-3min with the rotating speed of 100-200r/min; (F) obtaining slurry; (G) injecting the slurry into the mold for moulding; (H) maintaining it at 20 to 70 degrees C and a relative humidity of 90% to 95% for 20 to 40 hours; (I) releasing the mold; and (J) continuing to maintain at room temperature.
