Approximately 10 % of CO2 is emitted from an ordinary Portland cement production. In and concrete production, emissions can be greatly reduced by using Supplementary Cementitious Materials (SCMs). addition, the microstructure durability properties are improved when silica-rich SCMs used. this study, Eco-Friendly design was carried out three different SCMs. Diatomite, ground granulated blast fur...

Current blast furnace technology is a two-stage ironmaking process that requires that iron ore concentrate first be formed into pellets, fired at 1260°C, cooled, transported to the blast furnace, and then re-heated to approximately 1500°C to produce pig iron. This heating, cooling, and then reheating wastes a great deal of energy, which would be saved if the ironmaking process had only a single...
