This research developed eco-friendly UHPC using industrial by-products (Ground Granulated Blast Furnace Slag, Bottom Ash) by replacing cement and silica powder. The Chloride Penetration Resistances of the developed eco-friendly UHPC were evaluated. It is found that the developed eco-friendly UHPC shows adequate compressive strength and enhanced chloride durability.
