Title: STUDY ON CEMENT EFFECTIVENESS FACTOR OF FLY ASH OF CONCRETE USING FLY ASH CEMENT (TYPE-B)
Abstract: According to the investigation of research thesis, this paper describes the cement effectiveness factor of fly ash of concrete using fly ash cement (type-B). As the result, the main conclusions are as follows. The cement effectiveness factor of fly ash tends to increase as the unit of portland cement increases. The cement effectiveness factor (K) of fly ash are 0.7~0.9 in case of hydration heat, 0.25~0.5 in case of strength of 28 days, 0.6~0.9 in case of strength of 91 days, 0.4~0.55 in case of carbonation with outdoor exposure, 1.35~1.6 in case of salt penetration.
