Synthesis of metakaolin-based geopolymers with Controlled Nano Pore size

Geopolymers (GPs) are new inorganic polymers, which are produced by polycondensation of aluminosilicates [1, 2, and 3]. The geopolymerization reaction can be expressedaccording to the fig. 1 [4]:In this study, geopolymer particles with a controlled size of nonporous were synthesised in the presence of a solvent for the first time. Metakaolin was also used as the aluminosilicate source. Metakaolin-based geopolymers were produced withvarious compositions. The effect of the concentration of each of the four most important oxide components of inorganic polymers (Na2O, SiO2, Al2O3 and H2O) was assessed by porosimetry test.
