Fly ash is an extremely fine powder consisting of spherical particles less than 50 microns in size. Fly ash is one of the construction industry's most commonly used pozzolans. Pozzolans are siliceous or siliceous/alumina materials possessing the ability to form cementitious compounds when mixed with lime (calcium hydroxide, or Ca(OH) 2) and water.
The fly ash is generated at approximately 60% <45 microns, some of which is used for construction. The general highway concrete filler spec calls for 90% < 45 microns. Two RSG MCS-600 classifiers are employed to classify the ash to 90% <45 microns. The system was commissioned in 2009.
