Fly ash is a by-product produced while burning finely ground coal in a boiler to produce electricity. It is removed from the plant exhaust gases primarily by electrostatic precipitators or baghouses and secondarily by scrubber systems. Physically, fly ash is a very fine, powdery material, composed mostly of silica.
· For the cement/fly ash mixture, jet mill grinding also accelerated the rate of hydration. Finely ground blended I-GC60/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 ...
The binder is produced through joint grinding of portland cement, fly ash, and limestone together with superplasticizer using a vario-planetary mill. Grinding of active mineral supplements allows crystallization of ash particles as a result of the binding of Ca (OH) 2 during the hardening of alite, which intensifies the clinker mineral ...
