Description |
Geopolymers have been synthesized from mechanically activated lignite and brown coal y ash. Mechanical
activation of y ash has been carried out using laboratory ball mill. To determine the structural changes in both,
the y ash and the resulted geopolymer, Fourier transform infrared spectroscopy measurements were performed.
Isothermal conduction calorimetry method was applied to study the geopolymerisation reactions in mechanically
non-activated (raw) and activated y ash samples. The isothermal conduction calorimetry results showed similar
peak intensity for mechanically activated (530 min) y ash samples. However, the intensity of peak for 120 min
milled brown coal y ash was the highest. The compressive strength of the specimen was found to be dependent
on the grinding residence time as well as composition/type of y ash.
