IRJET- Experimental Study on Partial Replacement of Steel - ENVIRONMENTAL RESTORATION OF A STEEL MILL

Slag2PCC is a relatively complete process for co-processing steel slag and CO 2 and is presently under investigation in pilot and laboratory scales (Said et al., 2013). In the future, it will be necessary to focus on avoiding NH 3 losses from the solution and improving CO 2 dissolution in the solutions for the slag2PCC process.1. Most of the Tampa Mill property and some adjacent areas had been filled with materials that were generated by the steel mill, primarily slag, with lesser but still significant amounts of mill scale and dust from the air pollution control system (referred to as EC dust from "emission

Potentiality of Steel Mill Scale as Raw Material for - replacementof sand with steel slag in concrete

STEEL MILL SCALE: Mill scale is a steelmaking by-product from the rolling mill in the steel hot rolling process. Mill scale contains both iron in elemental form and three types of iron oxides: wustite (FeO), hematite (α-Fe2O3) and magnetite (Fe3O4). The chemical composition of mill scale varies according to the type of steel produced and the ...The drying shrinkage of cement mortar containing steel mill scrape (Fe 2 O 3 > 94%) and steel slag aggregate (Fe 2 O 3 = 89%) is lower than that of conventional cement mortar [Al-Otaibi 2008 ...

The experimental investigation involves study of physical, chemical and micro-structural characterization of mill scale. This provides the step one for its feasibility study in concrete industry. Before getting into the experimental results, a brief overview of the current research scenario is presented in the forthcoming section.The results of another investigation into BOF slag used as aggregate in stone mastic asphalt showed that it performs as well as the conventional asphalt pavement . Due to the instability and expansibility of steel slag, they performed an activation test with water until an expansion of about 1% was achieved.
