Fresh properties and compressive strength of high calcium …

 · In general, the setting time and workability values of LB fly ash are lower than KC fly ash as the calcium content of LB fly ash is higher than that of KC fly ash. The higher calcium content caused additional nucleation sites for precipitation of the fly ash dissolved species which accelerated the setting time and hardening process of the AAFA ( Lee and van Deventer, 2002b, Pangdaeng et al., 2014 ).
