Conductive geopolymer preparation method
The present invention discloses a conductive geopolymer preparation method which comprises the following steps of: 1) mixing graphene and a dispersant A with water, and grinding and dispersing the mixture to obtain a preliminary dispersed graphene dispersion liquid; 2) mixing an alkali metal silicate solution with the graphene dispersion liquid obtained in the step 1), mixing the mixture uniformly and then adding a dispersant B, grinding and dispersing the mixture to obtain a graphene dispersed alkali-activated solution, wherein the modulus of the alkali metal silicate solution is 1-4, and the solid content is 30-60%; 3) mixing a silicon-aluminum raw material with granulated furnace slag, and grinding the mixture to obtain composite geopolymer powder; and 4) mixing the composite geopolymer powder obtained in the step 3) with the graphene dispersed alkali-activated solution obtained in the step 2), and stirring the mixture uniformly to obtain the conductive geopolymer. According to the present invention, the geopolymer has good conductivity, and meanwhile the mechanical property of the geopolymer is maintained.
