Sample CW10 is a fly ash from incinerator of Calmova dumpsite (Slovak Republic). Fly ash CW11 is from a brown coal-fired power plant located in Hungary.
Fly ash was collected from boiler house. Fly ash was oven dried for 24 hrs for removing the moisture if any. Drying of fly ash will ease grinding. This dried fly ash was mechanically activated by grinding using mortar and pestle for size reduction. The grounded fly ash was sieved using a 200 Mesh BSS screen and the obtained particle size is 75 µm.

Fly ash is a waste material, obtained in huge quantities from thermal power plant as by-product of the burning of pulverized coal. It is a fine and powdery material. A microscopic view would reveal that the particles are essentially spherical. Fly ash has been used as spherical filler for the production of lightweight high strength concrete [6].
