1.5. 1.6 Slag Slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a …

Crushed Slag. Slag that has been crushed into a fine gravel. Crushed Slag is the result of crushing Slag in either a Stamp Mill or a Jaw Crusher .

The blast furnace slag can be crushed and processed into blast furnace slag aggregate by roller crusher and ground granulated blast furnace slag by ball mill. These two materials can be widely used in construction, infrastructure and agriculture.

Blast furnace slag is nonreactive in a high alkali environment, such as concrete and soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as 1774.

The cupola furnace from which the slag is granulated is a hot-air furnace with diameter 1000 mm where coke is used as a fuel; the charge consists of pig iron, fractional iron and scrap iron, fluxes (limestone) and FeSi. The cast iron melted in the cupola furnace is poured into a 6-tonne ladle in which it is desulphurized (using soda).

The crushed dolerite was used as natural coarse aggregate (CA) of 20 mm nominal size. The blast furnace slag was collected from the Rourkela steel plant. The results of standardized tests for aggregates are presented in Table 3 and the particle distribution curves of natural aggregates and GBS is given in Fig. 3, Fig. 4.

If the liquid slag is poured into beds and slowly cooled under ambient conditions, a crystalline structure is formed, and a hard, lump slag is produced, which can subsequently be crushed and screened. b) Granulated Blast Furnace Slag If the molten slag is cooled and solidified by rapid water

The granulated slag layer at the bottom of the drum creates a self filtering effect. After de-watering the residual moisture of the granulated slag is around 10 % to 12 %. The de-watered water is cleaned, cooled and recycled. The dried slag is conveyed to the granulated slag storage for dispatch to the customers.

Granulated slag Granulated blast furnace slag (GBS) is manufactured by rapidly chilling blast furnace slag with water which forms a glassy granular material with latent-hydraulic properties. It is used for cement, concrete, mortar, grout and aggregates. Granulated blast furnace slag has been used as a

Granulated blast furnace slag is crushed into finer particles. Then, an anti-caking agent is added to produce the final blast furnace slag fine aggregate product. Manufacturing of Blast Furnace Slag Fine Aggregate. Types by Particle Size. Type Particle Size (mm) Fractional mass through sieve (%)

Slag cement (Ground granulated blast- furnace slag): A hydraulic cement formed when granulated blast-furnace slag is ground to a suitable fineness. Granulated blast-furnace slag: The glassy, granular material formed when molten blast-furnace slag is rapidly …

calcium and other bases. Iron ore, limestone, and coke are crushed and blended into a mixture constituting the raw materials for molten iron, which is produced in a ±2700 °F blast furnace. The residual molten slag is chilled rapidly by immersion in water to vitrify the material into a …

Up to now, the main methods of using steel slag were used as sinter material, hot metal dephosphorizing agent, waste water treatment materials, reclamation of waste steel, concrete admixtures, CO 2 capture, agriculture and aggregate in construction etc. Typically, the crushed steel slag was used as coarse aggregate directly, for example, all ...

The present invention relates to an improved mineral binder composition comprising: - a mineral binder comprising at least 30 weight-% slag, based on the weight of the mineral binder, - an activator for the hydration of the slag consisting of or comprising calcium hydroxide and - a co-activator consisting of or comprising at least one salt selected from the group consisting of lithium ...

glassy sand with 97 % of the solid granulated slag particles less than 4 mm as shown in Figure 1. Granulated BF slag is regularly used by cement industry for making portland slag cement; however conversion of this slag into fine aggregate and use as replacement of river sand is an innovative and novel approach to recycle slags.

All the granulated slag samples were screened initially to obtain a size distribution. Crushed spoon and pot, as well as granulated slag, samples were split and pulverized for chemical analysis and X-ray diffraction (XRD), and also prepared as polished sections. These were examined using the ore microscope, imaged on the JEOL JSM-5400

As well as the protection of the environment against pollution, for this effect it is used as mixture of 15% of Crushed Granulated Blast Furnace Slag (CGBS) and 85% of Calcined Eggshell 142 Souhila ADJABI, Mohamed Salah NOUAOURIA, Wafa DJEBABLA Waste (CES). Different contents of this mixture were respectively used, namely: 5%, 10% and 15% ...

a cement replacement and this is the first in-depth characterization of air granulated steel slag. In this study converter slag was separated into different fractions (0.25-0.5 mm, 0.5-1 mm, 1-2 mm, 2-4 mm) after air granulation to study the influence of size and therefore cooling speed on its mineralogy. The air granulated slag fractions

Ground granulated blast-furnace slag, when used in general purpose concrete in North America, commonly constitutes between 30% and 45% of the cementing material in the mix (Fig. 3-4) (PCA 2000). Some slag concretes have a slag component of 70% or more of the cementitious material. ASTM C 989 (AASHTO M 302) classifies slag by its increasing level of

for looking to the quantum of requirements, quality and properties of Granulated blast furnace slag (GBS); this has been taken as a suitable material for replacing natural sand, M-Sand and crushed fine aggregates by its availability and properties.

Blast furnace slag, steel slag, granulated blast furnace slag, and wet bottom boiler slag are by-products of industrial processing and are classified as synthetic aggregates. 304 Aggregate Base Dotstateohus. Crushed air cooled blast furnace slag ACBFS 4. Granulated slag GS 5. Open hearth slag OH Crushed Carbonate Stone Limestone Used for 304.

The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production of that time to build their roads. Slag is particularly useful as an aggregate, due to the high mechanical resistance of the slag grains which exceeds those of many natural aggregates.

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, sand-size grains passing a …

2.1 Granulated Slag - Slag is a non-metallic product consisting essenti- ally of glass containing silicates and aluminates of lime and other bases, as in the case of blastfurnace slag, which is developed simultaneously with iron in blastfurnace or electric pig iron furnace. Granulated slag is obtain-

This slag is crushed, pulverised and screened for use in various applications, particularly in cement production because of its pozzolanic characteristics. Steel plants utilise cold slag for internal consumption and also for outside sale. The slag after cooling is crushed and used as road metal and railway ballast. Granulated slag produced in steel

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) 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 blast furnace slag is highly cementitious and high in calcium silicate hydrates (CSH) which is a strength enhancing ...
