Geopolymers are cement-like materials obtained by the chemical reaction between a powdered aluminosilicate precursor and an alkaline solution. Recently, researchers are studying alternative ways for geopolymer preparation in order to avoid the use of alkaline activators which are highly corrosive and difficult to handle in construction site works. These user-friendly materials are known as one-part geopolymers and appear as a cementitious powder that can polymerize only by water addition. This work deals with the use of potassium-rich biomass ashes for the activation of two types of one-part geopolymers.

Abstract
Geopolymers are cement-like materials obtained by the chemical reaction between a powdered aluminosilicate precursor and an alkaline solution. Recently, researchers are studying alternative ways for geopolymer preparation in order to avoid the use of alkaline activators which are highly corrosive and difficult to handle in construction site works. These user-friendly materials are known as one-part geopolymers and appear as a cementitious powder that can polymerize only by water addition. This work deals with the use of potassium-rich biomass ashes for the activation of two types of one-part geopolymers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
