Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.
Iron Blast Furnace Slag Aggregate for Concrete” in 1977 and fine BF slag aggregate as JIS A 5012 “Water Granulated Iron Blast Fur-nace Slag Aggregate for Concrete” in 1981. Thereafter, the two were unified as JIS A 5011-1 “Slag Aggregate for Concrete, Part 1 Blast Furnace Slag Aggregate”. Then, in 1983, the Japan Society of Civil
of utilizing the blast furnace slag as a replacement for natural aggregate in the concrete. b) The original scope of this research is to investigate the properties of concrete with blast furnace slag aggregates. c) To study the effect on compressive strength, and the flexural strength of concrete with blast furnace slag.
Here goes description. Basic slag is a co product of steelmaking and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route To flux the silica produced during steelmaking limestone and or dolomite are added as well as other types of slag conditioners such as calcium aluminate or fluorspar
Use of air-cooled blast furnace slag as supplementary. Nov 30, 2020 In turn, the slag that is not intended for this purpose is usually slowly cooled to reduce process costs, and is called air-cooled blast furnace slag (or simply air-cooled slag ACS).
porosity of slag. A pilot plant was constructed, and pro-duction of BFG under 1% became possible using this plant. 1. Introduction Due to the high porosity of blast furnace slag coarse aggregate (BFG), its water absorption is high (approximately 4%), and it is extremely difficult to con-trol the water content of the aggregate when BFG is
Granulated Blast Furnace Slag is obtained by rapidly chilling the molten ash of pig Iron from the blast furnace with the help of water. About Us A leading PAN India Distributors of Cement and building products.
The freshly produced air cooled blast furnace slag (FBFS) was obtained from an operating iron production plant, while the weathered air cooled blast furnace slag (WBFS) was obtained from an aggregate crusher plant which processes slag aggregate from a slag dumpsite comprising historical blast furnace slag deposits.
The roller crusher is suitable equipment for crushing blast furnace slag, which mainly depends on the extrusion between two rollers to realize the crushing of materials. The fineness of discharge can be controlled to 2-10mm with a handling capacity of 40 tons per hour.
Iron Blast Furnace Slag. Synthetic nonmetallic byproduct simultaneously produced with pig iron in a blast furnace that consists primarily of a fused mixture of oxides of silica, alumina, calcium, and magnesia. Manufactured Fine Aggregate. 100% crushed rock, gravel, iron blast-furnace slag, reverberatory furnace slag, or steel furnace slag.

A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate. Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3 , or dolomite, CaCO 3 ·MgCO 3 ) are melted together in a blast furnace.
The aggregate crushing value, 10% fines aggregate crushing value, flakiness index, plasticity and compaction characteristics of both slag aggregates complied with the South African specifications
At Overhall Aggregates and Recycling we have access to our own large fleet of locally maintained tipper lorries and a broad range of subcontract vehicles. We provide coverage across the North Lincolnshire, North East Lincolnshire, East Riding, Lincolnshire, Yorkshire and beyond for the supply of aggregates.
AIR COOLED SLAG • Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.

Fig 1: BF Slag Granulation PROBLEM Granulated blast furnace slags are available with steel industry for decades but were never accepted as a fine aggregate in construction activities till this developmental work. Several test have been carried out which confirms that granulated blast furnace slag is inert, non-toxic, free from traditional
Use of Blast Furnace Slag Aggregate in Concrete K.G. 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.

Both air-cooled blast furnace slag (ACBFS) and expanded blast furnace slag can be used as a conventional aggregate in embankment or fill. They are generally considered by many specifying agencies to be conventional aggregates and require minimal processing to satisfy conventional soil and aggregate engineering requirements.
The bulk relative density of expanded slag is difficult to determine accurately, but it is approximately 70 percent of that of air-cooled slag. Typical compacted unit weights for expanded blast furnace slag aggregates range from 800 kg/m 3 (50 lb/ft 3) to 1040 kg/m 3 (65 lb/ft 3). (6) Pelletized Blast Furnace Slag
