blast furnace slag aggregate cement to manufacture concrete

Use of Blast Furnace Slag Aggregate in Concrete KG Hiraskar and Chetan Patil AbstractThe 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

Granulated blast furnace slag GGBS Primarily used in the manufacture of concrete products as a cement replacement It has been used in cement combinations and as a cementitous component in concrete for many years and the use of GGBS will continue to help meet sustainability demands

The bulk density of pelletized blast furnace slag is typically 850 kgm 3 55 lb cf Appropriate production control ensures the formation of crystalline material which is preferable for use as aggregate this is in contrast to blast furnace slag pellets used in the manufacture of blast furnace cement Neville 2012 Experience has shown that

Foamed slag has been used as a lightweight aggregate for Portland cement concrete Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material and granulated slag have also been used as sand blasting shot materials

Douglas et al 1992 studied the properties and durability of alkaliactivated slag concrete They used granulated blast furnace slag and two different sodium silicates M s 147 or 122 and all mixtures incorporated an airentraining agent sulfonated hydrocarbon type For their freezethaw studies based on ASTM C 666 Procedure A they

Foamed slag has been used as a lightweight aggregate for Portland cement concrete Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material and granulated slag have also been used as sand blasting shot materials

This product is usually intended to be used in concrete either as an element of composite cement such as Blast furnace CementHigh Slag Blast Furnace Cement or as a straight addition to the concrete mix by the concrete producer GBFS Granulated Blast Furnace Slag GBFS can be used like sand as an additional aggregate for building materials

ground granulated blast furnace GGBF slag was reported as early as 1774 GGBF slag has been used in concrete in Japan and Western Europe since the 1940s Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe Blast furnace slag is used predominately as base and concrete aggregate

Blast furnace slag can also be used to make Ground Granulated Blastfurnace Slag GGBS which is used as a cement replacement in concrete Blast Furnace Slag Formed during the manufacture of iron molten blast furnace slag is cooled and processed in three ways to form slag aggregates for different applications

A mixture of cement products is known as Blended Cement or Mix Cement Ground Granulated Blast Furnace Slag GGBFSGGBS Ground Granulated Blast Furnace SlagGround Granulated Blastfurnace Slag is a GBFS that has been finely ground which has a cementitious properties like cement that can serve as an adhesive aggregate

Blastfurnace slag is produced in a blast furnace during the reduction of iron ore to iron It consists of nonmetallic minerals which are tapped off from the blast furnace while molten By processing blast furnace slag into Skyway Cement or slag aggregate the material is diverted from landfills

The main constituents of blast furnace slag are CaO SiO2 Al2O3 and MgO These are the minerals that are found in most of the cementitious substances The particles are further dried and ground in a rotating ball mill to form a fine powder known as ground granulated blast furnace slag cement

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 readymix concrete precast concrete hot mix asphalt aggregate septic drain fields and pipe backfill

Application of steel slag sand results reduced the cement clinker dosage and increasing the content of industrial waste products Use of non ground granulated blast furnace slag as fine aggregate in concrete was experimented by Isa Yuksel and Omer Ozkan 5

Cement is manufactured through a closely controlled chemical combination of calcium silicon aluminum iron and other ingredients Common materials used to manufacture cement include limestone shells and chalk or marl combined with shale clay slate blast furnace slag silica sand and iron ore
