The glass structure of the quenched glass largely depends on the proportions of silica and aluminum along with calcium and magnesium. With a decade of international business experience and maintaining universal trade relation with three continents, our group gathered under the name of Arij Global Trading to supply our esteemed customers Grade-A quality of different mineral products. Portland Cement Concrete. What is the Composition of BFS (Blast Furnace Slag). Sharjah Cement Factory purchases Slag mainly from NIPPON STEEL CORPORATION, Japan. If 50% of GGBS is used in a concrete mix, it can develop almost same 28 day strength as ordinary Portland cement. The slag shall contain no additions and shall conform to the sulfide sulfur and sulfate chemical composition requirement. Ground Granulated Blast Furnace Slag (GGBS) and Ordinary Portland Cement (OPC) [Quora] Chemical Composition of Ground Granulated Blast Furnace Slag The composition of slag essentially depends on the raw materials used in the iron production process. It is a recovered industrial by-product of an iron blast furnace. Throughout the period of chilling and becoming hard from its melted state, Blast Furnace Slag (BFS) can be cooled in numerous ways to procedure any of the different types of BFS products. Normal composition of portland cement is 30 % clinker, 5 % gypsum and 70 % blast furnace granulated slag. GGBS of Lafarge Emirates Cement conforms both to BS 6699:1992 & ASTM C 989-99 standards. The production of GGBS requires less than a fifth the energy and produces less than a fifteenth of the carbon dioxide emissions. The slurry composition cement is of a kind prepared by using blast-furnace slag cement of a specified type as the cement at a water/blast-furnace slag cement mass ratio of 40-250% and contains the admixture in an amount of 0.1-5 mass parts for 100 mass parts of the blast-furnace slag cement. Grade 80 has a low activity index and is used primarily in mass structures because GGBS concrete gains strength more steadily than equivalent concrete made with Portland cement. 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. In order to optimise the hydration reaction, pozzolanic materials, such as blast furnace slag and cement-kiln dust are added. Burning substantial and ore are supplied from the top while airflow is abounding from the bottom of the chamber. Granulated slag is quickly cooled by large amounts of water to produce a granule which is sand-like and is mainly ground into a cement generally known as Ground Granulated Blast Furnaces Slag (GGBFS), or Type S slag cement. Physical Properties of Ground Granulated Blast Furnace Slag (GGBFS) Ground granulated blast furnace slag have a color nearly white in appearance. Analysis of the slag at the factory for chemical composition using X-Ray Fluorescence, and glass content using X-Ray Diffraction. Making cement is energy intensive, generating up to 176 kg CO 2 for each tonne of concrete manufactured. A typical combination is 50% GGBS and 50% ordinary Portland cement. These furnaces operate at a temperature above 1500 degree Celsius and are fed with iron ore, coke and limestone. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. SiO 2 content of at least 60% and (b) a slowly cooled blast furnace slag powder having a glass content of at most 30%. This specification covers three strength grades of finely ground granulated blast-furnace slag (Grades 80, 100, and 120) for use as a cementitious material in concrete and mortars.
