The construction industry heavily relies on Portland cement, contributing to CO2 emissions and environmental degradation. This study explores using industrial byproducts—Ferrochrome Ash (FCA), Red Mud (RM), and Ground Granulated Blast Furnace Slag (GGBFS)—as sustainable partial cement replacements in green concrete. These materials enhance durability, reduce embodied carbon, and improve resistance to harsh environments. While FCA and RM enhance microstructure and lower sorptivity, GGBFS improves workability and reduces permeability. Optimal mix designs are crucial to balance strength and shrinkage risks. This review highlights the environmental, economic, and performance benefits of these materials, supporting circular economies and Sustainable Development Goals. Future research directions are discussed to enhance their feasibility.

摘要

The construction industry heavily relies on Portland cement, contributing to CO2 emissions and environmental degradation. This study explores using industrial byproducts—Ferrochrome Ash (FCA), Red Mud (RM), and Ground Granulated Blast Furnace Slag (GGBFS)—as sustainable partial cement replacements in green concrete. These materials enhance durability, reduce embodied carbon, and improve resistance to harsh environments. While FCA and RM enhance microstructure and lower sorptivity, GGBFS improves workability and reduces permeability. Optimal mix designs are crucial to balance strength and shrinkage risks. This review highlights the environmental, economic, and performance benefits of these materials, supporting circular economies and Sustainable Development Goals. Future research directions are discussed to enhance their feasibility.
