Durability of inorganic foam in solution: The role of alkali elements in the geopolymer network
► Investigations of geopolymer stability is a key point to define their application. ► The addition of silica fume to a geopolymer mixture lead to foam. ► The final products and their microstructure depend on the alkaline cation. ► Durability tests revealed the composition of geopolymer foam network...

| description | ► Investigations of geopolymer stability is a key point to define their application. ► The addition of silica fume to a geopolymer mixture lead to foam. ► The final products and their microstructure depend on the alkaline cation. ► Durability tests revealed the composition of geopolymer foam network. ► Zeolite phase is responsible for the degradation of the potassium foam.
The characterization of the behavior of inorganic foams in aqueous media is defined as a function of various parameters (initial pH value of the solution, alkaline element and aging of the foam). The final products and their microstructure depend on the alkaline cation in relation with the hydration shell. Durability tests revealed that the geopolymer foam network is based on three compounds: a dense geopolymer depending on the alkaline element, amorphous silica and M2Si2O5. For potassium foam, a fourth component was also evidenced: a zeolite that is partly responsible for the degradation of this foam. |
