This paper describes a review of the potential use of High Strength Incorporating Ground Granulated Blast Furnace Slag and Steel Fiber Reinforced Concrete used in construction industry to improve the structural strength and reduce steel reinforcements requirements. Blast furnace slag (GGBS) has been used as a supplementary material along with the cement. It helps in increasing the durability an...

This article discusses the existing calculation of heat for a coal-fired hot-blast furnace. By utilizing the standard method of heat calculation for boilers, considering the relation between the theoretical combustion temperature and the excess air coefficient of the boiler, combining some operational parameters of a coal-fired powder hot-blast furnace, the heat calculation of iron ore concentr...

It is attempt in pulverized coal injection (PCI) in blast furnace tuyeres to increase the injection rate without increasing the amount of unburned char inside the stack of the blast furnace. The unburned char can cause problems in the blast furnace operation, such as reduced permeability, undesirable gas/temperature distribution, excessive coke erosion and significant char carryover. In the nea...

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...

This research studies the properties of mortars incorporating waste materials including red mud (RM), ground granulated blast furnace slag (GGBFS), and electric arc dust (EAFD). Ordinary Portland cement (OPC) was partially replaced with equal contents RM, GGBFS, EAFD at different ratios by weight (0, 5, 10, 15, 20, 30, 40, 50%). Slump, compressive strength, splitting tensile electrical resistiv...

Worldwide, it is now known that industrial by-products rich in silicon (Si) and aluminum (Al) can be transformed by alkaline activation into so-called “green concrete”, an efficient sustainable material the field of construction; geopolymer material. In this work, materials produced using fly ash marble dust or blast furnace slag were studied to assess influence these substitutions on performan...
