The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, a solid that is free from voids ...
of all the steel manufactured worldwide comes from blast furnace/BOF In Europe each year approx. 30 million tonnes of blast furnace slag are produced (20% air cooled crystalline slag and 80% water granulated glassy slag), twothirds of the complete amount of blast furnace slag in Europe is used in the cement industry.
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) ballmilling of cement clinker for a period ranging between 3060 minutes in dry condition, (x) reducing size of granulated blast furnace slag by any process to obtain the size in ...
Blast furnace slag is known as a byproduct from the production of hot metal at integrated steel and iron mills. Approximately 300 kg of this liquid slag with a temperature of about 1500°C is tapped together with each ton hot metal. This results in a worldwide annual production of about 400 million tons of blast furnace slag.
After fine grinding blast furnace slag can be used as the main raw material for the production of slag powder. It can replace silicon bath soil insulation packing and save cost. It can be used for the production of slag bricks and wet grinding slag concrete products. It used for thermal insulation filler.
slag, or from wet bottom boiler slag. Blast furnace or steel slag is produced as a byproduct of iron or steel production. These materials are nonmetallic substances that rise to the surface of molten iron or steel during the smelting process. After being drawn off the surface of the melt, the slag is placed into a pit and is allowed to ...
Aug 09, 2014· Dry Granulation of Blast Furnace Slag for Energy Recovery Around 300 kg of liquid slag is produced as byproduct while producing one ton of hot metal in a blast furnace (BF). This slag is at a temperature of around 1500 deg C and has a sensible heat of approximately 400 M Cal per ton.
Synonyms: Slag cement, ground granulated blast furnace slag (GGBFS), granulated blast furnace slag (GBFS), Slag Product Form: Solid / powder or granular Intended Use of Product: Ground granulated blast furnace slag is used as an additive with portland cement in combination with water and aggregates to form concrete.
Aug 24, 2006· ground blast furnace slag is stable. ground blast furnace slag will not polymerize. ground blast furnace slag when wet may react with aluminum powder and other alkali and alkaline earth elements to liberate hydrogen gas. hydrogen sulfide gas may be released if the slag comes in contact with acids. hydrogen sulfide is a toxic gas.
permeable voids (VPV) and performance in wet–dry cycles for 50% FNS and 30% fly ash were better than those for OPC and natural sand. Keywords: ferronickel slag, fly ash, blast furnace slag, compressive strength, wet–dry cycle, porosity. 1. Introduction Substantial amounts of industrial byproducts are currently
In this study, a commercially available ground granulated blastfurnace slag (GGBS) was further processed by wet grinding, and WGGBS (wetgrinded GGBS) slurry with superfine particles was obtained. To avoid selfhydration of slag and augment the grinding efficiency, one commercially available polycarboxylate superplasticizer was added.
Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than mm (No. 4 sieve) in diameter to dense, sandsize grains passing a .
May 05, 2013· Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 – 1550 deg C temperature. Till seventies blast furnace (BF) slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.
Corrosivity: Blast furnace slag is mildly alkaline, with a pH in nonstagnant water mixtures in the range of 8 to 10. Despite the fact that blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate is slightly alkaline and does not present a .
Each year, approx. 400 million tons of blast furnace slag is produced worldwide with a tapping temperature of around 1,500°C. Currently, the slag is granulated in wet granulation plants using large volumes of water and to date it has not been possible to utilize the remnant heat energy of the molten slag, with approx. GJ of energy per ton.
Blast furnace slag production in Japan Production of blast furnace slag 290 kgslag/1000 kg iron ÆAnnual production of slag is 24 Mt. For one large scale blast furnace, production rate of melted slag (at about 1500℃) is 100 – 150t/hour. Solidified by natural cooling in atmosphere or rapid cooling by water. ÆHeat recovery has not yet been ...
Blast Furnace Slag as a Concrete Aggregate MF 1638 A. G. Timms NATIONAL SLAG ASSOCIATION Page 3 processed dry. It is sometimes supplied directly from the plants while it .
Nov 01, 2018· Granulated blast furnace slag (GBS) is a glassy byproduct of the steel industry that is formed during quenching of the molten slag after the blast furnace in a waterjet. To elucidate the cooling history of GBS, calorimetric scanning in the glass transition range and viscometric experiments at temperatures above the liquidus were performed.
aggregate, as expanded blastfurnace slag,9 and as a fine aggregate10,11 under the form of nongroundgranulated blastfurnace slag (nGGBFS) in concrete mixtures, but not in shotcrete mixtures. This project investigated the feasibility of using blastfurnace slag, in multiple forms, to produce drymix shotcrete mixtures with the explicit goals
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...
