FOAMED GEOPOLYMER FROM A TERNARY BLEND OF COAL FLY ASH, COAL BOTTOM ASH, AND RICE HULL ASH
Joshua Martin L. Kalaw
Abstract:
The thermal conductivity of geopolymer is generally low, making it suitable as a thermal insulation material. Thus, it is possible to develop this property and improve upon the material’s thermal properties by modifying the underlying microstructure. By modifying the internal structure of the material and increasing its porosity, the thermal insulation properties of the material may improve even more. Foamed geopolymer can be used for thermal insulation construction materials with comparable strength and better thermal conductivity than commercially available concrete. This study evaluated the effects of two different types of foaming agents, namely hydrogen peroxide and sodium perborate, in the production of foamed geopolymers as insulation material using a ternary blend.
In conclusion, it was observed that the porosity of the samples increased with the amount of foaming agent added.
