Study on the Mechanical Strength of Fiber-Reinforced Geopolymer Porous Materials

In this paper, fly ash and slag were used as themain rawmaterials, water glass was used as the activator, and hydrogen peroxide was used as the foaming agent, to prepare the geopolymer porous material, focusing on the analysis of the mechanical properties of the geopolymer porous material. Experiments shown that when the ratio of slag to fly ash was 3:7, the content of water glass was 40%, the content of hydrogen peroxide was 1.75%, the content of foam stabilizer was 0.5%, and the content of fiber was 0.6%, the mechanical properties of porous materials were the best: the density was 898 kg/m(3), the flexural strength and the compressive strength obtained under standard conditions for 60d were 3.3 MPa and 9.5 MPa, respectively.
