Slag is pulverized into a fine powder called ground granulated blast furnace slag and is used in this form as a cementitious component of concrete D Fly Ash Fly ash is the most widely used pozzolan in concrete It is a fine residue resembling cement that is a by-product of burning coal in an electric power generating plant Depending on the
pH Due to the effects of the limestone it contains, the pH of iron and steel slag increases to 10 – 12 when it reacts with water, indicating alkalinity that is the same or lower than that of recycled concrete base course material and cement-stabilized soil
Note the steel mill below, with its blast furnaces, and the raw materials for them: piles of iron ore pellets being offloaded from the ore freighter, AND piles of crushed limestone to be used for flux Source: Photograph by Randy Schaetzl, Professor of Geography - Michigan State University
Oct 01, 2019· Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloysLike other industrial byproducts, slag actually has many uses, and rarely goes to waste It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer
Slag As A Fertilizer , It seems that to be beneficial they must first have first entered into the structure of a plant or an animal There is no more common element in natural soils than potash It is a component of feldspar that goes to make up a large portion of soil on granite foundations , "As basic slag ,
The Second World War saw a steep increase in the use of these furnaces leading to the modern Electric Arc Furnace design operation and working principl These improvements to the processing of scrap steel comprised of larger more efficient and higher capacity furnaces; a 100T furnace would process the scrap in about an hour, using a transformer of 60MVA capacity

A: I think they’re asking about “basic slag”, a byproduct of steel making It’s commonly sold near Birmingham as a material The product is not typically found here because it’s so heavy to ship and garden lime is so cheap Tell them to have a soil test done (georgiasoiltest) and add lime as recommended Basic Slag
Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar .
