Foamed Geopolymer Composites with the Addition of Glass Wool Waste
This study examines foamed geopolymer composites based on fly ash from the Skawina coal-fired power plant in Poland. The paper presents the effect of adding 3% and 5% by weight of glass wool waste on selected properties of foamed geopolymers. The scope of the tests carried out included density measu...

The obtained results indicate that glass wool waste can be successfully used to lower the density and heat conduction coefficient of foamed geopolymer composites with a fly ash matrix. In addition, the results of changes in thermal radiation in the samples subjected to the temperature of 800 °C showed a positive effect of the addition of glass wool waste.

The obtained results seem promising for future applications. Such materials can be used in technical constructions as thermal insulation materials.https://www.mdpi.com/1996-1944/14/17/4978foamed geopolymerglass wool wastefly ashthermal conductivity coefficientthermal radiation changes |
