One part geopolymers activated with potassium-rich biomass ashes

Geopolymers are obtained by the chemical reaction between an aluminosilicate powder and an alkaline solution. Even if geopolymers do not contain Portland cement, they are similar to cementitious materials. Recently, many authors have tried to prepare geopolymers without alkaline activators, since they are user-hostile. These new materials are called one-part geopolymers and appear as a cementitious powder that can polymerize with water. The aim of this work is to investigate the possibility of using a potassium-rich biomass ash for the activation of one-part geopolymers
