The influence of the hydrogen peroxide incorporation content (0.25 – 1.25%) on density, compressive strength and thermal conductivity was evaluated. The experimental results show that the density and compressive strength were decrease with increasing content of hydrogen peroxide. However, the thermal insulating properties of the geopolymer foams were improved with increasing content of foaming agent. Geopolymers exhibiting thermal conductivity as low as 0.172 W/mK and a density of 0.5 g/cm3 were produced, showing the potential of these materials in applications requiring lightweight and low thermal conductivity materials. 2022 2022-03-15T01:07:56Z 2022-03-15T01:07:56Z 2019-08 Article IOP Conference Services: Material Sciences Engineering, vol.551, 2019, 6 pages 1757-899x (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/74635 https://doi.org/10.1088/1757-899x/551/1/012088 en IOP Publishing Ltd |
