Mechanical properties of geopolymer foam at high temperature

Popis výsledku v původním jazyce

In this work geopolymer foam composites containing waste basalt fibre (10 30 and 50%wt) were exposed to elevated temperatures of 200 400 600 800 and 1000°C. With an increase in high temperature the geopolymer foams material exhibits a decrease in compressive strength and bending strength. When heated above 600°C geopolymer foams materials exhibit a significant reduction in mechanical properties. It shows clearly with the naked eye that surface cracks in case of samples containing 10% of basalt filler. However when increasing fillers with basalt fibres up to 30% and 50% the cracking of the sample surface is no longer visible to the naked eye. Especially when the temperature increases the mechanical properties also increase without decreasing in the sample of 50% by weighing to the binder. The results show that reinforcing the geopolymer foams with basalt ground fibre improves the mechanical properties at high temperatures.
