  • Properties and Uses of Steelmaking Slag – IspatGuru

    14/11/2018· Usage in the production of cement and concrete – The presence of C3S, C2S and C4AF endorse steelmaking slag cementitious properties. It is generally accepted that the cementitious properties of steelmaking slag increases with its basicity. Hence, steelmaking slag ground into fine powder can be used as cement additives and concrete admixtures. When a mixture of fly ash,

  • Why use Fly Ash and Slag in Concrete? - Bay-Lynx

    With cement being the costliest ingredient, substituting fly ash or slag can help maintain a stronger mix at a lower cost. Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. The advantage of slag is its ability to substitute more of cement. Giving savings of up to 9% in cement cost with a 50% slag to

  • Steel Slag Usage in Cement | Industrial Efficiency

    Steel Slag Usage in Cement. About 100 – 200 kg of BOF slag is generated per ton of liquid steel. This material is often used in projects like road construction, but this route provides little energy efficiency gains. Steel slag can also be used in the cement clinker manufacturing process. The result is an increase in clinker production of up to 15% with no net increase in CO 2 emissions
