What is slag cement
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield desired reactive cementitious characteristics when ground into …

What is Slag Cement? (with pictures) - wiseGEEK
26.04.2020 · Slag cement was originally used as mortar in masonry projects. This type of cement is increasingly being used as an ingredient in the manufacture of blended Portland cement. Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent. Among the measurable improvements are higher workability, higher finishability, …
Steelmaking Slag - an overview | ScienceDirect …
04.04.2012 · Common slag treatment process in Japan is shown in Figure 4.4.12 [81].About 80% [79] of BF slag is quenched by water spray and the quenched BF slag sand produced is used mainly for cement, concrete and civil engineering resources.The rest is cooled by field air cooling and the slow cooled slag is used as a resource for road construction, concrete coarse aggregate, and so on.
Ground granulated blast-furnace slag - Wikipedia
Production and composition. The stone composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag. In the case of pig iron production the flux consists mostly of a mixture of limestone and ...

Euroslag - Euroslag
Ferrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is …
US7410537B2 - Process for the production of …
Accordingly, the present invention provides an improved process for the production of Portland slag cement using granulated blast furnace slag, which comprises: (viii) forming of cement clinker by known process, (ix) ball-milling of cement clinker for a period ranging between 30-60 minutes in dry condition, (x) reducing size of granulated blast furnace slag by any process to obtain the size in ...
Manufacturing process - Ciments Hoffmann
The manufacturing process for Hoffmann Green cements is based on the systematic use of abundant co-products as a substitute for natural resources. This innovation makes it possible to produce a carbon-free cement while preserving natural resources, particularly without the use of quarries. Also, with the absence of a firing process, the carbon impact of Hoffmann cements is significantly reduced …
Manufacturing - Skyway Cement
THE PROCESS Manufacturing Skyway Cement requires two basic processes, granulation and grinding. Granulation This process transforms molten slag into granules. Skyway Cement receives granulated slag from a US steel manufacturer in Gary, Indiana. In the blast furnace at the steel works, slag is produced when the mineral components of th e metal refining process separate from and float …
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 control of ...
