Blast-furnace slag is used in making-four classes of cement— ... The amount of slaked lime that is added to the slag for grinding into cement naturally varies considerably with the type of slag used. The latter, being a by-product, its composition depends very largely upon that of the ores, fluxes, and ash of the fuel used in the blast ...
The Crude Blast Furnace produces Steel Ingots and Slag by smelting Iron Ingots with Coal Coke or Charcoal as fuel. One Coal Coke burns long enough to smelt one ingot, which produces one Slag piece. A Block of Coal Coke smelts 10 ingots (so it's 11.11% more fuel efficient). A Block of Iron smelts in less time than 9 single pieces.. Coal Cokes come from roasting Coal inside a Coke Oven.
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g.

The GBFS powders were prepared with different GA, and their grindabilities, fluidities, reactivities and hydration characteristics were investigated. The experimental results indicate that although the improvement …
It is claimed: 1. The method which comprises grinding granular blast furnace slag to reduce the particle size thereof in the presence of an additive comprising a salt formed by reacting an amine and an aromatic group-containing carboxylic acid, the amount of said additive present being sufficient to enhance the efficiency of the grinding operation.
Fertilizer. Because of the fertilizer components CaO, SiO 2 and MgO in ground granulated blast furnace slag, it is used as calcium silicate fertilizer in rice cultivation.. By using granulated blast furnace slag, it improves harvest quantities and flavor by improving photosynthesis, reducing blight on lower leaves, preventing rice blast and promoting ripening.
Granulated blastfurnace slag is a very hard material and as a result necessitates the use of high wear resistant materials in the grinding process. The grinding process takes account of mean particle size, grading (particle size distribution), fineness and the particle shape in order to ensure that when used in concrete performance is maximised.
Most of the Portland blast-furnace slag cement used in the world is made by inter-grinding the granulated slag with Portland cement clinker. Since the slag is usually the hardest to grind, it forms the coarsest portion of the final product while the cement is ground the finest. The slag is slower setting and, for optimum performance, should be
