Experimental Investigation of Hematite Fines Reduction to Magnetite with Coal and Coke Fines
Abstract: In this current investigation, we aimed to comprehensively examine how various key processing parameters influence the reduction of hematite particles enveloped by coal and coke fines. This reduction process took place in an externally heated cylindrical steel container, which we will call the "work tube." This work tube had a diameter of 70 mm and a height of 300 mm and was situated within a pot furnace. For the experimentation, …

Efficient Conversion of Sponge Iron from Iron Ore-Coal Composite
Abstract: Today India stands as the largest producer of coal based sponge iron using calibrated ore and non-coking coal. Production of sponge iron, via the direct reduction route using rotary kilns, continues to experience significant growth in India. Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. …

Utilization of Pond Ash as a Partial Replacement of Fine Aggregate Using Alccofine in Conventional Concrete
Abstract: Pond ash is the byproduct and is produce from coal plants. These plants release byproduct in major quantity which effects the environment. In this paper, an experimental work has been done on the conventional concrete with pond ash as replacement of fine aggregate. The grade of the concrete is M-40 and nine concrete mixes named as F1, F2, F3, G1, G2, G3, G4, G5 and G6 were prepared with different …

Properties and Characteristics of Lean Concrete Made with Recycled Coarse Aggregate and Fly Ash
Abstract: Qualitative aggregates have become scarce and expensive in various places in India, due to rapid enhancement in infrastructure activities essential for the development of new construction facilities. The use of waste materials in construction appears to be an attractive proposition because of their low cost, environmental considerations and depleting source of quality aggregates, if good performance can be ensured through appropriate technology. The problem of disposal of waste generated from …
