Resources, Conservation and Recycling 40 (2003) 71–80 Recovery of silica gel from blast furnace slag Maurizia Seggiani∗, Sandra Vitolo Dipartimento di Ingegneria Chimica, Chimica Industriale e Scienza dei Materiali, Università di Pisa, Via Diotisalvi 2, 56126 Pisa, Italy Received 10 January 2002; accepted 28 January 2003 Abstract This work concerns a process for the recovery of silica ...
Nov 11, 2016· To determine the factors that influence the diameter of granulated particles, a paraffin test platform for gas quenching granulation was established. The influences of air velocity, air flow rate, liquid mass flow rate, and liquid pipe diameter on the final particle .
Abstract: An experimental programme is planned to study the effect of using copper slag (CS), granulated blast furnace slag (GBFS) and silicomanganese slag (SiMn) as fine aggregate on the properties of concrete.
Blast furnace slag is known as 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 means a worldwide annual production of about 400 million tons of blast furnace slag.
The process uses ambient temperature synthesis to produce geopolymer cement from two major industrial waste, fly ash and granulated blast furnace slag. .
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.
The ground granulated blast furnace slag (GGBFS) is a byproduct of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree ...
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 mm (No. 4) sieve.
Jan 02, 2019· Slag is commonly aircooled in large pits and used for landfill or used for roadbased materials after crushing and screening. In some modern integrated steelworks, molten blast furnace slag is granulated using water jets — producing a glassy product which can be used as valuable feed in cement manufacturing by replacing ordinary Portland cement and significantly reducing the .
Abstract: Alkaliactivated systems, formed by the alkaline activation are inorganic materials characterized by the potential of ecological use. The objective of experiment was to investigate the influence of different activators on selected properties of alkaliactivated systems based on granulated blast furnace slag.
Blast furnace (BF) slag is the principal byproduct formed during the ironmaking process, which generates a considerable amount of thermal energy. However, to simultaneously recover the maximum amount of residual heat and obtain vitreous slag using a low conduction coefficient of air is a primary challenge of the dry granulation technique, which has not been solved by either fundamental ...
While substitution of ground granulated blastfurnace slag for up to 70% of the portland cement in a mix has been used, there appears to be an optimum substitution percentage that produces the greatest 28day strength. This is typically 50% of the total cementitious material but depends on the grade of ground granulated blastfurnace slag used.
The slag used in the process is a nonmetallic substance formed simultaneously with iron in a blast furnace. As the slag is discharged from the blast furnace, it is quickquenched with water becoming a granulated glass of sandlike consistency. The slag is then ground to a particle size comparable to Portland cement.
DRY SLAG GRANULATION WITH HEAT RECOVERY* Ian James McDonald1 Andrea Werner2 Abstract Each year, approximately 400 million tons of blast furnace slag is produced worldwide with a tapping temperature of around 1,500°C. It is normally used as a substitute for cement clinker or as an aggregate material in road construction.
