The effect of high calcium fly ash on the formation of cement properties with its participation

摘要

In the present study, the activity of high calcium fly ash was evaluated on the basis of comparison of compressive strength binder containing 10 to 90% addition of ash to the strength CEM I Portland cement mortar. Physical and mechanical properties of Portland composite cements CEM II/A,B-M(S-W), CEM II/A,B-M(W-V) and CEM II/A, B-M (W-LL) with the addition of high calcium fly ash were presented. It was found that the high calcium fly ash (W), in particular after mechanical activation may constitute a valuable main component of cement. It was found that the presence of high calcium fly ash increases the boundaries of flow and plastic viscosity of mortars.
