ABSTRACT:
A synthetic Class C fly ash results from a substantially homogeneous blend of about 40-60% by weight of a Class F fly ash and about 60-40% by weight of cement kiln dust (CKD). This new fly ash can replace about 25-50% by weight of portland cement in conventional formulations with coarse and fine aggregate for making general purpose concrete and particularly ready-mix concrete with comparable compressive strength and like properties.
