DETAILED DESCRIPTION - Composite alkali-excited solid waste type high-performance inorganic adhesive comprises 15-25 wt.% slag powder, 15-25 wt.% steel slag powder, 10-20 wt.% super fine powder of laterite silver slag, 10-20 wt.% ferrochrome ultrafine powder, 3-7 wt.% compound alkali activator, 0.1-0.5 wt.% graphene oxide and 20-35 wt.% water. The slag powder is granulated blast furnace slag powder with 25-45 mu m particle size. The steel slag micropowder is hot pressed slag micropowder, air quenched slag micropowder, molten iron desulfurization slag micropowder, casting residual slag micropowder, converter hot slag micropowder, converter drum slag micropowder, electric furnace hot slag micropowder and/or electric furnace drum slag micropowder. The steel slag is granulated blast furnace slag powder with 25-45 mu m particle size. The compound alkali activator is sodium hydroxide and water glass at mass ratio of 3:1-1:3. The sodium hydroxide is industrial pure. The water glass is industrial pure. The graphene oxide is Brodie method graphene oxide, Staudemaier method graphene oxide and Hummers method graphene oxide. The water is deionized water.
