Evaluation of steel slag and crushed limestone mixtures as …

01/03/2013· Adding steel slag to the limestone aggregates increases the resistance to deflection and vertical strain. While, with increasing the steel slag percentage a little increase in radial stress is achieved. Moreover, the effect of SSP on the vertical stress along the horizontal distance can be neglected. The advantages of steel slag addition are clearly manifested in reducing the rutting and …

Limestone and Steel Slag Leach Beds – Mine Closure

Steel slag contains high concentrations of soluble alkalinity, primarily as Ca(OH) 2 and Ca-(Fe)-silicates. The high neutralization potential of steel slag provides a feasible passive treatment option for AMD impacted waters that require buffering beyond the capacity of limestone (Simmons et al. 2002, Mack & Gutta 2009).

All rights reserved. Keywords: Clinker; Portland cement; Granulated blast-furnace slag; Compressive strength 1. Introduction

Lime, an essential component in the steel industry

Calcite or lime is used in the steel industry because of its flux action which allows it to lower the concentration of impurities in the steel (above all silica and alumina, but also sulphur, phosphorus…) and so produce slag. To achieve this oxygen is blown through the molten iron, bringing about a fall in the percentage of carbon. In contrast, the silicon and the phosphorus, form oxides which because of their …

Iron and Steel Slag Statistics and Information - USGS

Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a …

portland cement. Slags (especially steel slag) can be used as a partial substitute for limestone and some other natural raw materials for clinker (cement) manufacture and compete in this use with fly ash and bottom ash. Some other metallurgical slags, such as copper slag, can compete with ferrous slags in some specialty markets, such as a ferrous

Slag - Wikipedia

Slag is drawn off the furnace just before the molten steel is poured into ladles for ingotting. Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags.
