grain slag cement

  • Engineering Seminars: SLAG CEMENT - Blogger

    Slag cement should be substituted for Portland cement on a one-to-one basis by mass. Specific gravity of slag cement ranges from 2.85 to2.94, depending upon the slag cement source-as compared to 3.15for Portland cement. The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of Portland cement.

  • Blast Furnace Slag Cements – Phase Analysis Using ...

    Jun 21, 2011 · Blast furnace slag is mostly an amorphous product, comprising little amounts of crystalline phases such as Akermanite (Ca 2 MgSi 2 O 7), Merwinite (Ca 3 MgSi 2 O 8), or Quartz (SiO 2). It offers hydraulic properties same as those of Portland Cement and thus may partly substitute the clinker component in cement blends.

    GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged.

  • 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.

  • Portland Slag Cement (PSC)

    Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC.

  • Specific Gravity Of General Materials Table - CSGNetwork

    The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

    of the dried red mud is 23.53 m2/g and the average grain diameter is 2.75 lm. The average grain diameter of red mud is even smaller than that of micro-cement (4–6 lm). The small particles can provide a packing effect on binder matrix and strength development so that strength reduction due to efflorescence can be compensated (Al-Akhras and Smadi 2004).

  • Slag Cement Suppliers & Manufacturers - CEMEX USA

    Slag cement lowers the heat of hydration of a concrete mixture, which reduces the risk of early age thermal cracking, a major benefit for large or mass concrete placements. It lowers the total alkalis of a concrete mixture thus reducing the risk of alkali-silica reactions. Equally important, slag cement delivers improved workability.

    When adding any translucent color to anything, the pattern and colors of the substrate will show through. It's similar to applying a wood stain to a piece of wood with knots and wood grain. Concrete stain can actually highlight and intensify the variations found in the concrete — natural as well as man-made blemishes and markings.
