In recent years, Supplementary Cementitious Materials (SCMs) are widely used for concrete as a partial replacement of cement with the intents to reduce greenhouse gas emission, the amount of waste to be landfilled and the usage of natural resources.Fresh and hardened properties of concrete can be improved by SCMs.Slag and Fly Ash (FA) are the SCMs which commonly used as a partial replacement of cement.workability and rheological properties of concrete and mortar have been improved by GGBFS.FA is used in blended cement with a focus on workability, durability, strength and cost of concrete but the carbon content of FA inhibits the action of air entraining admixture.
