Nevertheless, both of them cause a delay in the compressive strength gain. The following findings were obtained.

Potential environmental impacts 15 8. Ground Granulated Blast furnace Slag (GGBFS) siliceous and aluminous Blast furnace slag is a by-product of iron manufacturing industry.

Reduction tests of the agglomerates were carried out to investigate the high temperature properties of the agglomerates. The blast-furnace slag is the by-product of the ironmaking process. The molten slag at a temperature of about 1500°C * The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including: Dicalcium Silicate (Ca 2 SiO 4 ) 14284-23-2, Merwinite (Ca 3 MgSi 2 O 8 ) 13813-64-4, and Gehlenite (Ca 2 Al 2 SiO 7 ) 1302-56-3. Material composition and quality standards 13 7. containing 25% replacement of ordinary Portland cement (OPC) by ground granulated blast-furnace slag cement (GGBFS) with 3000 cm2/g fineness. Fly ash and blast furnace slag were used in a systematic replacement of cement at the levels of 25%, 50%, and 70%. ; BLAST F [,'RNA CE SLAG.

Ground Granulated Blast furnace Slag (GGBS)[1] is a by product from the blast furnaces used to make iron. A coke bed is formed between the cohesive zone and the deadman at the bottom of the blast furnace, and the molten iron and slag formed at the cohesive zone descend to the coke bed. Cylindrical specimens, shaped by pressing the blast furnace slag containing clay, were sintered at 1150, 1175 and 1200°C for 1h. Executive summary 1 1. Granulated ground blast furnace slag (GGBFS) is a key constituent of CEM II/A-S, CEM II/B-S and CEM III cements. [dour. Introduction 3 2. Materials and Methods 2.1. Tapped molten blast furnace slag being directed into ladles at the Ford Rouge River Complex near Detroit, Michigan. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. Now in Ukraine the blast-furnace slag is treated by impinging much water for granulation. Key markets and production of BFS 5 3. The sustainable shotcrete mixture contained both fine and coarse pelletized blastfurnace slag aggregates. HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". Slag from the steel mills was used as artificial fertilizer only if it came from the processes that used phosphorous pig iron as raw material to produce steel (so called Thomas slag).

Compared to this, elsewhere furnaces up to 5070 m 3 had been built. PDF FILE - CLICK HERE FOR PRINTABLE WORKSHEET A simplified diagram of a Blast Furnace is drawn below. A. These liquid products are drained from the furnace at regular intervals. Blast furnace slag (BFS) A technical report on the manufacturing of blast furnace slag and material status in the UK. ..... 7 Figure 6. Blast Furnace Slag Blast-furnace slag for roads Cements from blast-furnace slag Blast-furnace slag hydration. 374KB Sizes 1 Downloads 74 Views. 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. Process description 11 6. Overview; Product Details; Standard Number: BS EN 15167-1:2006: Title: Ground granulated blast furnace slag for use in concrete, mortar and grout. 3-5), also called slag cement, is made from iron blast-furnace slag; it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. Continue flushing until advised to stop by a Poisons Information Centre, a doctor, or for at least 15 minutes. The iron ore is reduced to iron and the remaining materials from a slag that floats on top of the iron. Ladle containing molten blast furnace slag being dumped into a cooling pit at the Ford Rouge River Complex. blast furnace slag in order to use the agglomerates as raw materials in the blast furnace. Format HARDCOPY. Iron ore, coke and limestone are fed into the furnace, and the resulting molten slag floats above the molten iron at a temperature of about 1500°C to 1600°C.
