K<sub>2</sub>O-Metakaolin-Based Geopolymer Foams: Production, Porosity Characterization and Permeability Test
In this paper, four near-net shaped foams were produced via direct foaming, starting from a benchmark metakaolin-based geopolymer formulation. Hydrogen peroxide and metallic silicon were used in different amounts as blowing agents to change the porosity from meso- to ultra-macro-porosity. Foams were...
