Nano silicon dioxide and hybrid fiber reinforced geopolymer concrete capable of improving abrasion resistance and preparation method of nano silicon dioxide and hybrid fiber reinforced geopolymer concrete
The invention belongs to the technical field of geopolymer concrete, and provides nano silicon dioxide and hybrid fiber reinforced geopolymer concrete and a preparation method thereof. The geopolymer concrete is prepared from the following raw materials: a cementing material, aggregate, an alkali activator, a reinforcing material and water, the mass ratio of the fly ash to the slag powder in the cementing material is (3.5-4.5): 1; the mixing amount of the fly ash in the geopolymer concrete is 410-418kg/m < 3 >; the mass ratio of the aggregate to the alkali activator to the cementing material is (2.5-3.5): (0.35-0.39): 1; the reinforcing material is prepared from nano silicon dioxide with the mass mixing amount of 1.2 to 1.8 percent, polyvinyl alcohol fiber with the volume mixing amount of 0.4 to 0.8 percent and steel fiber with the volume mixing amount of 1.0 to 1.8 percent. By doping the nano silicon dioxide hybrid fibers, the abrasion resistance of the geopolymer concrete can be enhanced.
