It typically replaces part of the portland cement in concrete mixes. According to the Slag Cement Association, an industry trade group, incorporating slag cement as a supplement in concrete offers higher strength, reduced permeability and improved resistance to chemical attack.
The Precast/Prestressed Concrete Institute (PCI) offers a broad spectrum of resources for architects and engineers, including design specifications for both architectural and structural applications.

For Portland cement concrete, and slag concrete with substitution ratio 10%, 20%, 30%, and 50%, and water cement ratio of 0.48, the estimated time for the chloride ion to diffuse into 5 cm depth of the concrete and to reach a concentration of 0.20% is about 15.7 years, 16.3 years, 28.6 years, 38.6 years, and 22.9 years, respectively.
Flexural strength is usually improved by the use of slag cement, which makes it beneficial to concrete paving applications where flexural strengths are important. It is believed that the increased flexural strength is the result of the stronger bonds in the cement-slag-aggregate system because of the shape and surface texture of the slag particles.

Slag cement is often referred to as “ground granulated blast-furnace slag” (GGBFS). As requested in 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).
1. Scope. 1.1 This specification covers three strength grades of slag cement for use as a cementitious material in concrete and mortar. Note 1—The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirements of Specification C595 or as a separate ingredient in concrete or mortar mixtures.
emittance of 0.9 for concrete and solar reflectance values of 0.35 for "new typical gray concrete" and 0.7 for "new typical white concrete." It also reports default SRI values for new gray and new white concrete of 35 and 86, respectively. The default SRI values for weathered gray and weathered white concrete are 19 and 45, respectively.
ACI Committee 234, Silica Fume in Concrete, is developing information on the use of silica fume for a committee report. Proportioning GGBFS concrete is discussed in ACI 226-1R (now ACI Committee 233). When additional data becomes available, it is expected that an ACI guide for proportioning concrete with these materials will be developed.

In our area, people are discussing the benefits or disadvantages of finishing exterior concrete containing ground granulated blast furnace (GGBF) slag. One group claims that since slag is finer than portland cement, a finisher brings more fines to the surface after straight edge and floating and thus creates a less durable surface.
