Slag cement helps reduce permeability, sulfate attack, and alkalisilica reaction creating a longer lasting and more resilient concrete. Slag cement is a recovered material from the iron production process, thus reducing the environmental impact of concrete mixtures. Improved Finishability. Most concrete made with slag cement will have lessGet Price

When substituted for portland cement in quantities between 25 and 65, slag cement plays a vital role in reducing permeability in concrete. SCIC 6, Reducing Permeability, explains how lowpermeability concrete has a reduced potential for corrosion of reinforcing steel, and provides a brief discussion of how standard test method ASTM C1202

The ground granulated blast furnace slag GGBFS is a byproduct of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace.
Active Members Member organizations are actively engaged in iron and steel slag processing, refining, andor the marketing of these slags. Allied Members Organizations involved in servicing or providing products pertaining to the slag producing organizations. Associate Members
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.
Type IS PortlandSlag Cement. Type IP PortlandPozzonlan Cement. Type IT Ternary Blended Cement. In addition, some blended cements have special performance properties verified by additional testing. These are designated by letters in parentheses following the cement type. For example Type IP MS is a portlandpozzolan cement with moderate

What are the benefits of using slag cement A. The hydration products of slag cement are generally found to be more gellike less crystalline than the products of hydration of portland cement thus, they reduce the permeability of the cement paste ACI 233R. Slags are used as a replacement of portland cement in amounts typically between 25
2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement ACI Committee 233, 2004. The term slag cement will be used throughout this paper when referring to finelyground granulated blastfurnace slag.
Groundgranulated blastfurnace slag GGBS or GGBFS is obtained by quenching molten iron slag a byproduct of iron and steelmaking from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a finegranulated blast furnace slag is highly cementitious and high in CSH calcium silicate hydrates which is a strength enhancing
The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced Blastfurnace slagThe nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast furnace.
Slag cement helps reduce permeability, sulfate attack, and alkalisilica reaction creating a longer lasting and more resilient concrete. Slag cement is a recovered material from the iron production process, thus reducing the environmental impact of concrete mixtures. Improved Finishability. Most concrete made with slag cement will have less
The use of slag cement is also an extremely effective way of reducing the potential for sulfate attack 1. How does Slag Cement Mitigate Sulfate Attack The use of slag cement reduces the likelihood of sulfate attack in three ways Slag cement does not contain C 3 A, so its addition in concrete dilutes the total amount of C 3 A in the system.

In most concrete made with slag cement, the surface becomes light gray or white within hours after the concrete surface has been exposed to direct sunlight and air. If greening does occur, it usually appears within a week of concrete placement and typically disappears within a week, after oxidation starts.
