    As a binder, it can replace approximately 7080 wt. of Portland cement, with 910 reduction of CO 2 emissions from concrete manufacturing for every 10 of Portland cement replaced 37. Used as an aggregate, slag usually replaces fine grade aggregate and can improve the concretes properties.

  • Usage Of Steel Slag In Concrete As Fine Andor Coarse

    In this study, the use of steel slag as fine andor coarse aggregate in concrete is investigated. For this purpose, 12 different concrete mixtures with different watercement ratios of 0.40, 0.55 and 0.70 which include steel slag aggregate as fine andor coarse aggregate are prepared.

  • Applications Of Steel Slag Powder And Steel Slag Aggregate

    Due to the high density of steel slag, concrete containing steel slag aggregate has a higher density than plain cement concrete does . In addition, concrete containing steel slag aggregate displays satisfactory compressive strengths and flexural strengths 2830. Ultrahigh performance concrete UHPC is a new type of cementbased material.

  • Tarmac Steel Slag Aggregates Asphalt Cement

    Steel slag is produced during the steel making process where, after air cooling, a dense rock material is processed and sized into specific products suitable for diverse applications. These include construction aggregates, rail ballast, agricultural soil amendment, in the manufacture of Ordinary Portland Cement and as an environmental

  • Tarmac Slag Aggregates Aggregates Asphalt Cement

    In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense readymixed concrete. Blast furnace slag can also be used to make Ground Granulated Blastfurnace Slag GGBS which is used as a cement replacement in concrete.

  • Use Of Steel Slag Aggregate In Pavements Report November

    Steel slag aggregate SSA is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense SSA is 2030 heavier than naturally occurring aggregates such as basalt and granite.

  • Ground Granulated Blastfurnace Slag Wikipedia

    How GGBS cement is used. GGBS cement can be added to concrete in the concrete manufacturer39s batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a onetoone basis by weight.

  • Common Uses For Slag National Slag Association

    Other uses Include, skid resistant asphalt aggregate, rail ballast asphaltic concrete aggregate, soil conditioner, hard stand areas and unconfined construction fill. Electric Arc Furnace Slag EAF or steel furnace slag Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into

  • Blast Furnace Slag Material Description User

    Although blast furnace slag contains a small component of elemental sulfur 1 to 2 percent, the leachate tends to be slightly alkaline and does not present a corrosion risk to steel in pilings 10 or to steel embedded in concrete made with blast furnace slag cement or aggregates.

  • Blast Furnace Slag Cement Manufacture Properties And Uses

    Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70 to that of cement. Ground granulated blast furnace slag cement GGBFS is a fine glassy granules which contain cementatious properties.

  • Utilization Of Steel Slag For Portland Cement Clinker

    The steel slag was mixed with other raw materials, such as limestone, clay, sand, and bauxite, in appropriate proportions in order to produce the raw meal to be tested for the production of Portland cement clinker PC SS.A reference raw meal PC Ref, without steel slag, was also synthesized for reasons of chemical analyses of the raw materials used are given in Table 1.
