Sulfate resisting cement is used in construction exposed to severe sulphate action by water and soil in places like canals linings, culverts, retaining walls, siphons etc. 7. Blast Furnace Slag Cement. Blast furnace slag cement is obtained by grinding the clinkers with about 60% slag and resembles more or less in properties of Portland cement.
A need was felt to identify potential alternative source of aggregate to fulfill the future growth aspiration of Indian construction industry. Use of slag as aggregates provides great opportunity to utilize this waste material as an alternative to normally available aggregates.
Steel slag is a byproduct obtained from steel industry. It is generated as a residue during the production of steel. Because of the high disposal cost as a waste material and the overall positive ...
Under the quality protocol you can process the correct waste steel slag to make specified unbound, semibound or fully bound aggregate products for use in the civil engineering and construction ...
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
The ready mixed concrete industry consumes about 75% of the cement shipped in the Besides portland and blended cement it uses a large quantity of industrial byproduct material that would otherwise be considered waste products. These include fly ash from the coal burning power plants, slag from the manufacture of iron and silica fume from ...
The technologies of obtaining green materials are available, but their use in construction industry is limited. The building material and construction industry is one of the principal users of wastes in the processes for obtaining materials or products, for constructing bridges or highways, in soil stabilization, in hydraulic construction, etc.
Characterization of Mill Scale for Potential Application in Construction Industry
Copper slag blasting edia/grit is manufactured of the granulated slag of copper refineries, and used for blastcleaning of metal surface. Copper slag has also gained popularity in the building industry for use as a fill material. Contractors may also use copper slag in place of sand during concrete construction.
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. Blast furnace slag products have been used successfully in virtually all phases of bridge construction.
Coal slag – abrasive blasting. According to OSHA, coal slag abrasive blasting (using coal slag as the blasting agent) is the most common exposure to beryllium in construction. For many applications, coal slag has replaced sand as the blasting agent because of .
