Pressure-resistant geopolymer composite material and preparation method of pressure-resistant geopolymer using same
The invention discloses a pressure-resistant geopolymer composite material and a preparation method of a pressure-resistant geopolymer using the same. The pressure-resistant geopolymer composite material comprises the following raw materials in parts by mass: 54-71 parts of metakaolin, 22-32 parts of an alkali activator, 3-6 parts of steel fiber, 0.5-1 part of graphene and 1-5 parts of an auxiliary agent. The alkali activator comprises a potassium silicate solution and a sodium silicate solution, and the mixing ratio of the potassium silicate solution to the sodium silicate solution is (2-3):(1-2). According to the pressure-resistant geopolymer composite material provided by the invention, the hardened pressure-resistant geopolymer has ultrahigh compressive strength and elastic modulus, so that the defects in the prior art are overcome. The invention further aims to provide a preparation method of the pressure-resistant geopolymer using the pressure-resistant geopolymer composite material, the steps are simple, the operability is high, and the ultrahigh compressive strength and elasticity modulus of the pressure-resistant geopolymer are favorably realized.
