The formation and regulation mechanisms of pore structures in porous geopolymers (PGs) remain qualitatively unclear, posing significant challenges to their practical application and performance optimization. In this study, PGs were synthesized utilizing metakaolin as the primary raw material and hydrogen peroxide as the foaming agent. Three distinct surfactants—sodium dodecyl sulfate, hydroxypropyl methylcellulose, and cetyltrimethylammonium bromide—were incorporated to fabricate three unique categories of PGs. The mechanical properties that ...
