Mechanical Strength and Microstructure Properties of Concrete
3.2. Workability of the Copper Slag Concrete. Concrete workability refers to its capacity for easy placement, compaction, and finishing without facing issues such as separation or bleeding. Factors such as the water-to-cement ratio, the quantity and nature of the aggregate, and the incorporation of chemical admixtures influence this attribute.
