Nano silicon dioxide and hybrid fiber reinforced geopolymer concrete capable of improving compressive strength and preparation method of nano silicon dioxide and hybrid fiber reinforced geopolymer concrete
The invention provides nano-silica and hybrid fiber reinforced geopolymer concrete for improving compressive strength and a preparation method thereof, and belongs to the technical field of geopolymer concrete. The geopolymer concrete is prepared from geopolymer concrete and a reinforcing material, the mixing amount of fly ash in the raw materials of the geopolymer concrete is 568-580 kg/m < 3 >, and the mass ratio of the fly ash to aggregate to an alkali activator to water is (4.6-4.8): (11-12): (1.6-1.8): 1; the mass ratio of water glass to sodium hydroxide in the alkali activator is (175-185): (26-30); the doping amount of the nano silicon dioxide is 0.5-2%; the volume mixing amount of the polyvinyl alcohol fiber is 0.2-0.8%; the volume mixing amount of the steel fibers is 0.25-1.0%. The nano silicon dioxide, the polyvinyl alcohol fiber and the steel fiber are doped into the geopolymer concrete, so that not only can the working performance of the geopolymer concrete be improved, but also the compressive strength of the geopolymer concrete can be improved.
