Ground Granulated Blast Furnace Slag - an overview ...

While substitution of ground granulated blast-furnace slag for up to 70% of the portland cement in a mix has been used, there appears to be an optimum substitution percentage that produces the greatest 28-day strength. This is typically 50% of the total cementitious material but depends on the grade of ground granulated blast-furnace slag used.

Slag in concrete | LEEDuser

Aug 27, 2010 · Blast furnace slag is a waste product of the iron-making process. It is a glassy granule that is ground up and used as a cement admixture. Slag contributes to compliance under MRc4 as post-industrial recycled content. It is most easily available in steel producing regions, though is often shipped around the country.

Slag - Wikipedia

As the slag is channeled out of the furnace, water is poured over it. This rapid cooling, often from a temperature of around 2,600 °F (1,430 °C), is the start of the granulating process. This process causes several chemical reactions to take place within the slag, and gives the material its .

Electric Arc Furnace Steelmaking using Scrap

Electric Arc Furnace Tests. For all tests, the furnace was preheated by inserting a propane burner through the slag door and preheating for approximately 12 h. The initial charge of shredded auto scrap, reductant, and slag formers was top charged to the furnace by means of a charging bucket. The amount of scrap in this initial charge was 450 lb.
