GGBFS derives from a byproduct of the steel industry produced by adding limestone flux to the ore to remove nonferrous contaminants. This raw product is then milled to a fine powder form for its intended use. All significant constituents are listed below: Chemical Entity Proportion CAS Number Granulated Blast Furnace Slag >90%
effect of slag granulation water temperature on density. It was found that under optimum conditions of granulation parameters, the bulk density of the slag can be increased to > 1350 kg/m3 as more compact structure can be developed in slag granules. Micrographs of the low temperature water spray granulated material shows
Ground granulated blast furnace slag. Ground granulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steel making) from a blast furnace in water or stream, to produce a glassy granular product that is then dried and ground into a fine powder. Additional recommended knowledge.
Incompatible Materials: Slag is incompatible with acids, ammonium salts and aluminum metal. Slag and cement dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Slag and cement reacts with water to form silies and calcium hydroxide.
Tenova Pyromet has vast experience in the design and construction of wet granulation plants. The wet slag granulation process involves pumping water into the slag cold runner via a blower box to quench the molten slag. The inhouse designs have been proven in numerous appliions and have shown to be both robust and reliable.
09/10/2020 · The ground granulated blastfurnace slag is a byproduct of the iron and steel production process under the closed blast furnace technology. Thanks to the ultrafast cooling by high pressure water, blast furnace slag is a very good active mineral additive for cement, concrete and has been used for a long time in the world as well as in Viet Nam.
Groundgranulated blastfurnace slag (GGBFS) is a byproduct of iron and steelmaking obtained by quenching molten iron slag from a blast furnace in water or steam. Used to increase the strength of concrete and used to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product.
activity than granulated slag. This is also due to the presence of free quartz silica which acts as nucleating agent that tends to increase the rate of hydration with ﬁred sludge [17,18]. Combined water contents The combined water contents of hydrated granulated slag cement pastes as a function of curing time are presented in Fig. 3.
(GBFS) Granulated blastfurnace slag is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine is suitable for appliions in marine environment, mass concreting and sulphate environment, water retaining structures, basement and other ...

spraying with water. This results in a crystalline, rocklike aircooled slag. Granulated slag is formed when the molten slag is cooled rapidly by jets of pressurized water, resulting in a vitreous, granulated slag. Steel Making Slag:
Ground granulated blast furnace slag is an environmentally friendly product. Mixing this material into cement improves the chemical resistance, watertightness, fluidity, and longterm strength of concrete. This material also significantly helps reduce cracking (exothermic suppression) and inhibit alkali aggregate reactions.
Iron and steel slag. Products. Granulated blastfurnace slag. Granulated blastfurnace slag is produced by using water to rapidly cool molten slag. This type of slag is sold as a raw material for cement in Japan and overseas. Inquiry
Steel Slag BOF slag, commonly known as steel slag is another waste from Iron Steel Industry. It has shown potential for use as a raw mix component up to 10% in the manufacture of cement clinker. Steel slag can also replace granulated blast furnace slag up to 10% in the manufacture of Portland Slag Cement. Steel slags are produced at steel melting
The rapid cooling of molten slag by large quantities of water produces sandlike granule aggregate. Primarily ground into a cement replacement known as ground granulated blast furnace slag (GGBS) this is used in readymixed and precast concrete and masonry, floor levelling compounds and high temperature resistant building products.
Slag. Groundgranulated blastfurnace slag (GGBFS) is produced by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder. When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of ...
temperature of about 1,500°C) with a jet of highpressure water. Granulated slag is vitreous and looks sandy. It is similar in chemical composition to Portland cement and hardens when it reacts with water. Therefore, about 80% of granulated slag is used as a raw material for cement. The remaining about 20% of blast furnace slag is air
slag to granulated slag within 35 minutes Small footprint Concentrate on the discharge of steam, is conducive to the installation of dust removal devices, reduce air pollution Grain processing, storage silo slag, dust less to avoid environmental pollution better separation between slag and steel higher metal .
The water granulation conditions for producing high density, coarse granulated blast furnace slag were investigated in a laboratoryscale experiment. The influence of the slag temperature, water temperature and nozzle shape on the density and grain size of the granulated slag was clarified.
