Abstract: This paper deals with the determination of the k-value and activity index for power plant fly ash with CEM I 42.5 R cement and CEM II/A-M (S-V) 42.5 R cement. The objective is to determine the activity index of this active admixture for different cement replacements to determine the k-value based on the relationship between water coefficient and compressive strength for fly ash and to assess the effect of different cement types on the kvalue. Based on the results obtained, the effect of blended cement, which has a higher amount of active admixture than Portland cement, on the compressive strength, the activity index and the k-value of fly ash was assessed.
Keywords: active admixture; activity index; Concrete; fly ash; k-value
