Use: Ground Granulated Blast Furnace Slag is a supplementary cementitious material that is a partial replacement for Portland Cement in concrete and other similar products. Few reports have studied slag binders with high slag proportions (>90%) and low-cost activators (solid waste is used) that have higher performance than cement for backfilling. A blast furnace is a block that smelts ores and metal armor and tools, similar to a furnace, but at twice the rate. About 60% of the blast furnace slag is made into granulated slag as a cement mixing material. Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. 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. The amount of GGBS in it may vary from 30 to 70%. A Guide to the Use of Iron Blast Furnace Slag ii Cement and Concrete. Fly ash and blast furnace slag were used in a systematic replacement of cement at the levels of 25%, 50%, and 70%. The report models supply and demand for fly ash and granulated blast furnace slag up to 2030. Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, … Use of Blast Furnace Slag Aggregate in Concrete K.G. The beneficial effect of blast furnace slag on the alkali silicate reaction was reported in [44], and the effect has two parts: First, blast furnace slag cement has a denser pore structure than Portland cement, and this hampers different transport processes needed for alkali silica reaction. This process leads to a glassy, granular product that is then dried and ground into a fine powder. 1.3 Details of the supplier of the product The concretes that contain blast furnace slag cement have less permeability, low hydration heat, better operability and processability, higher strength, and higher resistance to hazardous chemicals and hazardous attacks in many forms as compared to the … ash and Ground Granulated Blast Furnace slag cement (GGBFS) for R82 – lean mix concrete subbase [1], and also fly ash and/or GGBFS for R83 – Concrete Pavement Base [2], where reactive aggregates are used. On reaching the casing point, a mixture of drilling fluid, chemical activators, and high concentrations of hydraulic blast furnace slag are pumped in. Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portland cement. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace. Slag. The heart of the process is the blast furnace that refines iron ore into iron. Ground-granulated blast-furnace slag (GGBFS) is produced by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder. Enviroment ® is a Ground Granulated Blast Furnace Slag which complies with AS3582.2 as supplementary cementitious material. Civil engineering works. 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. Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. The gypsum will be added as the usual ratio, like the manufacturing of OPC. Section 2: Hazards Identification Hazardous Substance. The molten slag must first be separated from the molten iron. Slag is a by-product from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). Emission Factors For Concrete Constituents* * As defined by Australian Standard AS13795. Slag Cement The blast furnace slag cement is used in the world in order to increase the strength of the concrete and reduce the costs. This also reduces the volume of mud that needs to be disposed of. Blast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability. 1 a INTRODUCT Throughout the world there is an increasing focus on the need to recycle and to more fully utilise by-products of manufacturing processes in an attempt to conserve our finite natural resources. Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as “slag”, is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. Cockburn Cement markets Ground Granulated Blast Furnace Slag (GGBFS). Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blastfurnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete. Portland Blast Furnace Slag Cement is particularly suitable for rivers, ports, roads and tunnels. Granular Water Granulated Slag Cement, Water Granulated Blast-Furnace Slag Cement Relevant identified uses of the substance or mixture and uses advised against: Building materials, construction, a basic ingredient in concrete. Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement. Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. Using granulated blast furnace slag can save energy by 20-40%, reduce costs by 10-30%, and reduce CO 2 emissions by 44%. GGBS are used to produce two types of cement such as Portland Blast Furnace Cement (PBFC) and High Slag Blast Furnace Cement (HSBFC) with varying amount of GGBS. slag aggregates, ground granulated blast furnace slag (GGBFS) and slag mixed with clinker in cement production.
