mix (Type I PC) and two 70% by weight ground granulated blast furnace slag (GGBFS) mixes (Type II Low Heat PC). One of the slag mixes contained a high range water reducer (HRWR). Tests for compressive strength, freezethaw durability, rapid chloride permeability, and salt scaling were conducted on field samples. Results showed that the
(2) Granulated slag is the glassy, granular product formed when the molten blast furnace slag is rapidly chilled by immersion in water. Basic Use: Aggregates are used for all types of base and subbase construction. In addition to applications requiring graded aggregates, pit run blast furnace slag is extensively used for subbase
Ground Granulated Blast furnace Slag (GGBS)[1] is a by product from the blast furnaces used to make iron. These operate at a temperature of about 1500 degrees centigrade and are fed with a carefully controlled mixture of iron ore, coke and limestone. The iron ore is reduced to iron and the remaining materials from a slag
Slag cement, or ground granulated blastfurnace slag (GGBFS), has been used in concrete projects in the United States for over a century. Earlier usage of slag cement in Europe and elsewhere demonstrates that longterm performance is enhanced in many ways.
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 ...

2(a) Classification of the Chemical: Granulated Blast Furnace Slag is considered a hazardous material according to the criteria specified in REACH [REGULATION (EC) No 1907/2006] and CLP [REGULATION (EC) No 1272/2008] and OSHA 29 CFR Hazard Communication Standard.
Granulated blast furnace slag is the glassy material formed by water quenching of molten slag discharged from the blast furnaces in the ironmaking industry. The water quenching process is termed granulation and its product, granulated blast furnace slag, is sandlike in appearance.
Ground granulated blast furnace slag (GGBFS) has been used for many years as a supplementary cementitious material in Portland cement concrete, either as a mineral admixture or as a component of blended cement. The use of GGBFS in Portland cement is governed by AASHTO M302. (1) Three types of ground granulated slag cements are typically ...
In the absence of special circumstances, the use of ground granulated blast furnace slag as a cement replacement should be limited to grades 100 and 120 ground granulated blast furnace slag and in the absence of special circumstances or mix specific data, the substitution of ground granulated blast furnace slag should be limited to 50 percent ...
Granulated Blast Furnace Slag or GBFS is the residue of combustion in the furnace of the steel refining process. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
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 ...
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.
Dec 18, 2015· Groundgranulated blastfurnace slag is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a ...
Oct 14, 2019· Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. furnaces are fed with a controlled mixture of ironore, coke and limestone, and operated at a temperature of about 1,500° granulated slag is further processed by drying and then grinding in a vertical roller mill of rotating ball mill to ...
The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve. The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete.
GGBS (Ground Granulated Blast Furnace Slag) is a pozzolanic material used in concrete. Read its proscons, uses, properties effect on properties of concrete
Groundgranulated blastfurnace slag (GGBS or GGBFS) 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 powder.
Ground granulated blastfurnace slag (GGBFS) or Slag Cement 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 powder. GGBFS is used to make durable concrete structures in
Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
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.
Ground granulated blastfurnace slag, more commonly referred to as slag or slag cement, is a byproduct of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated ...
Mar 14, 2018· During the drilling process for piles we encountered water in all pile trenches and the concrete has to be casted in the water as we cannot drain the water, but contractor does not want to use water proofing admixture as ground granulated blast furnace slag (GGBS) is .
Granulated Blast Furnace Slag. GBFS/GBS Granulated Blast Furnace Slag/Granulated Blastfurnace Slag berbentuk butiran/pasir merupakan residu pembakaran pada tanur (furnace) dari proses pemurnian baja atau produk samping dari pabrik baja seperti PT Krakatau Steel (Persero) Tbk. dan anak perusaannya PT Krakatau Posco.
