For the cement/fly ash mixture, jet mill grinding also accelerated the rate of hydration. Finely ground blended IGC60/GF40 mortar had greater surface area and was more reactive, thus resulting in the increase in hydration and higher compressive strength. At the age of 28 days, the strength of GC60/GF40 even exceeded that of the C reference ...

of the fly ash fineness on the rheology of the geopolymer paste and the properties have been investigated. The raw fly ash was ground in a ball mill for various duration, 5, 10, 20, 30, 60 and 120 min. Geopolymer paste was prepared from the raw and ground fly ash with NaOH sodium silicate mixture as alkaline activator.

The first system is a blend of OPC and 15% limestone, and the second system is a blend of OPC and 40% fly ash. It was observed that when jet mill grinding is used, the average particle size of the powders is decreased to approximately 4 μm or less with a narrower particle size distribution than that achieved using ball milling.
