Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature

What is Slag? (with pictures) wiseGEEK

May 24, 2020In appearance, slag looks like a loose collection of aggregate, with lumps of varying sizes. It is also sometimes referred to as cinder, in a reference to its sometimes dark and crumbly appearance. Aluminum is a common component of slag, along with silicon and magnesium. This substance is produced during the smelting process in several ways.

Steel Slag Aggregate an overview ScienceDirect Topics

A bulk steel slag aggregate sample is considered. The apparent total volume is V o, the volume of solid is V, and the ratio V/V o (or γ o /γ s) is a measure of the denseness of the mass of steel slag (expressed as D).The volume expansion is defined as the ratio of increase in volume to the real volume (solid) of steel slag; that is,
