leaching; concrete manufacturing 1. It is used as a mud cake modifier for the cementing of oil and gas wells.. It is a by-product of the iron-making industry. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine … Blast furnace slag is a non-metallic residue usually obtained from steel plants or from the reduction of ores in a blast furnace. Blast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability. I had practically used PPC cement in almost all projects. Slag cement is often referred to as “ground granulated blast-furnace slag” (GGBFS). It has been found that using a slag mix for cementing is beneficial economically and technically as well as better for the environment than Portland cement. Best workability (evaluated by slump and Table tests) was recorded at 30% of BFS addition. Top Blast Furnace Slag suppliers in world are South Africa (35%), Japan (13%) and India (7.4%). Some of top companies that supply Blast Furnace Slag are AfriSam (South Africa), JFE Steel Corporation (Japan) and Tatametaliks (India). Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. Cement / Concrete. Ground granulated blast furnace slag is commonly used in combination with Portland cement in concrete for many applications[10,11] 7. When slag, a by-product of the iron-making process, is quenched with water and rapidly chilled, it forms a glassy granulated material of sand-like consistency. Introduction Blast furnace slag (BFS) is a non-metallic industrial by-product, which is produced in blast furnaces by the melting of the iron ore, producing molten pig iron [1]. Today, the main by-product of hot metal production in blast furnaces is granulated blast furnace slag (GBS, see statistics).After grinding to cement fineness (GGBS = ground granulated blast furnace slag) it is used as a main constituent of cement or as a separate concrete addition. Ground Granulated Blast Furnace Slag (GGBS) has been constantly in use as cement replacement for sustainable infrastructure. A typical combination is 50% GGBS with 50% Portland cement, but percentages of GGBS [4] anywhere between 20 and 80 % are commonly used. The heart of the process is the blast furnace that refines iron ore into iron. Finely ground slag may be blended with portland cement or added to other ingredients at the mixer. Ground Granulated Blast Furnace Slag (GGBFS) is a fine glassy granule which encompasses cementitious possessions. Hiraskar and Chetan Patil Abstract-The Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement. The Concrete Society, Cementitious Materials: The effect of ggbs, fly ash, silica fume and limestone fines on the properties of concrete Cementitious materials; References. GGBS Concrete GGBS Proportions On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. 1.1 This specification covers three strength grades of finely ground granulated blast-furnace slag for use as a cementitious material in concrete and mortar. Francis Flower recycles blast furnace slag from the steel industry for production of ground granulated blast furnace slag for use in cement production, among other offerings for industrial and agricultural use. It is actually a byproduct of iron production. Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. 2 天前 Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement.
