  • Slag Aggregate an overview ScienceDirect Topics

    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.

  • Steel Slag an overview ScienceDirect Topics

    Wear resistance: The wear resistance of steel slag cement is twice that of PC; the separated slag particles consisting mainly of fine iron particles. Nonremoval of these materials would make the slag much more difficult to grind. Magnetic reseparation is absolutely necessary, if the steel slag is to be used for manufacture of SSBC, and to ensure that the very fine particles are removed

  • Grey correlation analysis between strength of slag cement

    Abstract The particle size distributions of slag powder were investigated by Laser Scatter equipment. The influence of particle fractions of slag powder on the compressive strength of slag cement composed of 50% slag powder and 50% Portland cement was also studied by the method of grey correlation analysis. The results indicated that the volume fraction of particles 5–10 μm had a

  • Steel-slag: a supplementary cementious Global Cement

    The cement uses only 15-30% of OPC clinker, 30-40% of steel-slag and 40-50% of blastfurnace slag (BFS), allowing for great reductions in GHG emissions, consumption of virgin natural resources and energy use by between 70% and 85%. The characteristics of steel-slag as a supplementary cementitious material are also discussed.

  • What is slag cement

    Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.

  • Mechanical Properties of Concrete Using Steel Slag Aggregate

    During the production of iron and steel, fluxes (limestone and/or dolomite) are charged into blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces iron ore into molten iron product. Fluxing agents separate impurities and slag was produced during separation of molten steel. Slag is a nonmetallic inert waste byproduct primarily consists of
