- ItemThe Influence Of Modified Fly Ash Particles By Heating On The Compressive Strength Of Geopolymer Mortar(Chemické Listy, 2012) Xiem, Nguyen, Thang; Louda, Petr; Kroisova, Dora; Trung, Nguyen, Duc; Thien, NguyenN. Xiem, P. Louda, D. Kroisova, N. Trung, and N. Thien (Department of Material Science, Faculty of Mechanical Engineering, Technical University of Liberec, Czech Republic): The Influence of Modified Fly Ash Particles by Heating on the Compressive Strength of Geopolymer Mortar In this study, 2 types of fly ash from Czech Republic power plants were investigated with respect to composition. Fly ashes particles are heated at high temperature up to 1000 degrees C to remove the contaminant (unburnt carbon) and the color become brighter can be observed by a naked eye. However, the high processing temperatures can slightly influence on the final properties of the fly ash and geopolymer mortar. After heating fly ash particles at 1000 degrees C, the compressive strength of samples can be reduced slightly when comparing with original fly ash.
