This study assessed the environmental effects and cost of the Industrial Waste addictive Blast Furnace Slag (W-BFS) using Life Cycle Assessment (LCA) and compared it to general BFS. The environmental impacts of W-BFS were as follows: 1.12ˆ10´1 kg-CO 2 eq/kg, 3.18ˆ10´5 kg-Ethylene eq/kg, 4.79ˆ10´4 kg-SO 2 eq/kg, 7.15ˆ10´4 kg-PO 4 3´e q/kg, 7.15ˆ10´4 kg-CFC 11 eq/kg and 3.94ˆ10´3 kg-Antimony eq/kg. Among the environmental impact category, GWP and AP were 9.28ˆ10´2 kg-CO 2 eq/kg and 3.33ˆ10´4 kg-SO 2 eq/kg at a raw material stage, accounting for 80% and 70% of total environmental impact respectively. In EP, POCP and ADP, in addition, raw material
