NOVELTY - Graphene oxide-silane coupling agent-geopolymer composition material comprises 100 pts. wt. silicon aluminum material, 35-80 pts. wt. alkali activator, 0.7-7 pts. wt. silane coupling agent hydrolysate, 0.01-0.07 pts. wt. graphene oxide, 0.03-0.2 pts. wt. dispersant, where the silicon aluminum raw material is metakaolin, fly ash, coal gangue or slag. USE - Used as graphene oxide-silane coupling agent-geopolymer composition material. ADVANTAGE - The composition material: has rich sources, uses industrial solid waste, and is economical and environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene oxide-silane coupling agent-geopolymer composition material, comprising (i) adding graphene oxide to an alkali activator and dispersant, mechanically stirring for 10-20 minutes, and then carrying out ultrasonic dispersion for 30-60 minutes to obtain suspension; (ii) adding silico-alumina raw material to the suspension of step (i), stirring at 1050 revolutions/minute at a speed for 2-3 minutes, then adding silane coupling agent hydrolysate at a speed of 100-200 rpm, stirring for 1-3 minutes to obtain a slurry; and (iii) injecting the slurry of step (ii) into a mold for molding, then curing for 12 days, demolding, and continuously curing for 3-28 days at room temperature.
