EFFECT OF MILLING TIME ON MECHANICAL PROPERTIES OF FLY ASH ...

It can be observed by SEM that fly ash fineness increases with ball milling treatment. The analysis shows that the BET surface area is greater in samples with longer grinding time (15 hours). The rate of hydration of mixtures with ground fly ash content was higher in comparison with the untreated fly ash and this follows from the results of strength development.
