Hydration, rheology, and strength of ordinary portland cement(OPC)-cement kiln dust(CKD)-slag binders

摘要

This study investigates the characteristics of a binder system containing cement kiln dust(CKD), blast-furnace slag, and ordinary portland cement(OPC). The system consists of 0 to 50/100 CKD and 0 to 75/100 slag replacement for Type I cement, with a total amount of supplementary cementitious materials equal to or less than 75/100. The study evaluates the heat of hydration, rheological behavior, and flexural and compressive strengths of pastes and mortars made with these binders. It also examines the effects of binder proportions on concrete properties.
