We are offering a wide range of Granulated Blast Furnace Slag to our valuable customers. These Granulated Blast Furnace Slag are made of high grade raw material. It is used to make cement and concrete and it can save the content of cement so that it can save the cost of concrete. This quenching process leads to transformation
ground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag has been used in concrete in Japan and Western Europe since the 1940s. Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe. Blast furnace slag is used predominately as base and concrete aggregate
Apr 10, 2013 · Fig 1 Granulated and air cooled BF slag. 1. Granulated blast furnace slag – When liquid slag is cooled and solidified by rapid water quenching to a glassy state, little or no crystallization occurs.This process results in the formation of sand size (or fritlike) fragments, usually with some friable clinker like material.
Mar 21, 2020 · Chemical properties of different types of ferrous slag vary depending on the specific production process. A common characteristic of these slags is that they result from lime and silica based melts, therefore calcium oxide (CaO) and silica (SiO2) are their primary components. Other components include alumina (Al2O3) and magnesium oxide (MgO).
determined by ITM 206, Scratch Hardness, and structurally weak material as determined by visual inspection. Coke and Iron Coke and iron are of concern only with the slag materials. Coke is an ingredient in the iron making process. Slag from these furnaces normally are free of objectionable amounts of coke and iron. Chert
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
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 4.75 mm (No. 4 sieve) in diameter to dense, sandsize grains passing a

blast furnace slag hardness grind blast furnace slag hardness grind. Blast Furnace Slag Grinding Europe laxmitravels . 201895 Pfeiffer for grinding granulated blastfurnace slag and granulated blastfurnace slag cements. The mill will be used at a new 160t/hr slag grinding plant at the cement producer''s Bayyavaram Village
Granulated blast furnace slag – GBFS (SLAG GRANULES) Ground granulated – GGBFS (SLAG POWDER) Slag is a nonmetallic byproduct of the steelmaking process sourced from blastfurnaces which is mostly used to make iron. It is converted to granulated blast furnace slag (GBFS) by quickly cooling molten slag with industrial water or steam.
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 4.75 mm (No. 4 sieve) in diameter to dense, sandsize grains passing a
Slaglime cements—ground granulated blastfurnace slag is not hydraulic on its own, but is "activated" by addition of alkalis, most economically using lime. They are similar to pozzolan lime cements in their properties. Only granulated slag (i.e., waterquenched, glassy slag) is effective as a cement component.
This paper reports the physical properties and hydration products of slag cement that was prepared by activating ground granulated blast furnace slag with commercial lime and plaster of Paris (POP) as activators. The consistency, setting times and soundness of various mixes of slaglimePOP is reported. The hydration products and formation of bonds in the paste during setting were studied with
new trends in the use of granulated slags in road construction /in french/ sandgravelslag and sandslag are defined as mixtures prepared in the mixing plant with a high proportion of freshly manufactured granulated slag activated with fat lime.
obtained access to slag supplies, small but profitable businesses have been developed serving a diversity of niche markets. The most common current use of granulated slag is for abrasive cleaning of surfaces and the physical properties of granulated solids related to this use are fairly well documented such as size, specific gravity and hardness.
Steelmaking slag Because of its hydraulic property and the large bearing capacity it can provide, steelmaking slag is used as a road base course material. With high particle density and hardness, this slag has superior wear resistance and for this reason is used as an aggregate for asphalt concrete.
Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include. Blending with many other products such as granulated slag, fly ash and lime to form pavement material, skid resistant asphalt aggregate and unconfined construction fill.
The study concerns the synthesis and properties of Al/GS composites based on powder metallurgy techniques. Dilatometry, differential thermal analysis, and scanning electron microscopy were employed to track the reactions between the aluminum matrix and the granulated slag
Granulated slag samples were collected when the industry adopted water cooled slag granulation process. Lumped slag samples were collected from the air cooled slag after material recovery. Pictures of the slag samples are shown in Fig.3.1. and 3.2. Fig. 3.1 Photographs of water cooled granulated ferrochrome slag Chapter 3
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 byproduct of an iron blast furnace.
Nov 25, 2018 · Granulated slag, BF slag, Class, Crystalline structure, Expanded slag, Liquid slag, Water quenching, Properties and Uses of Ironmaking slag The majority of iron in the world is produced in the blast furnace (BF) and hence BF slag represents the largest quantity of ironmaking slag produced around the world.
Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. These operate at a temperature of about 1, 500 degrees centigrade and are fed with a carefully controlled mixture of ironore, coke and limestone.
4 Aggregate Specifiions and Requirements Physical Quality Requirements Fine Aggregates Coarse Aggregates Scratch Hardness, 40 percent. For aircooled blast furnace sl ag or granulated blast furnace slag sand, the acid insoluble content is required to not be less than 25 % for this
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
the maximum density and hardness in steel slag which account for about 20–30 wt.% of steel slag) introduced defects in concrete Utilization of carbonated and granulated steel slag aggregate
The slag obtained has the composition almost similar to the chemical composition of ordinary Portland cement. Molten slag consists of aluminous and siliceous residues and then water is sprayed quickly to get glassy granulate in nature. And then dried, grounded to the required size which is known as Ground granulated Blast furnace Slag.
