Grindability is an important factor for the characteristic of the brittle raw materials by the design the mills. As grindability depends on many unknown factors, hardgrove grindability index (HGI) is determined empirically using a sample mill, according to the following procedure. The device to measure the hardgrove grindability consists of a ...
During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
Steel mill slag often can be used safely for non-structural fills such as roadway embankments, landscaping, aggregate for asphalt concrete pavements, etc. (The chemical content of the slag should be evaluated along with its physical characteristics.) However, problems can arise when steel mill slag is present beneath structures that are ...
