Using Slag Cement in Sustainable Construction

Making Concrete Greener with Slag Cement Slag cement is a byproduct of iron production in a blast furnace. It is a hydraulic cement that can replace between 20 to 80 percent of the portland cement in concrete (depending on application, see Table 1) and helps makes concrete even greener. Slag cement contributes the following sustainability ben-

Slag Cement - an overview ScienceDirect Topics

Although slag cement has been reported to improve workability, increase cohesiveness, and reduce water demand, the angular and irregular slag cement particles do not benefit as much from the “ball-bearing effect” that was described for the spherical fly ash particles (Lang Geisler, 1996). The surface characteristics of slag cement do, however, create smooth slip planes, which do not absorb as much

What Is Slag Cement? Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.

What is slag cement

Slag cement is a hydraulic cement while fly ash is a pozzolan. This information sheet lists the properties slag cement can bring to concrete in both plastic and hardened form. For example, the addition of slag cement usually results in reduced need for water, faster time of set, improved pumpability and finishability, higher 28-day strength, lower permeability, resistance to sulfate attack and alkali-silica

The proportion of slag cement is usually dictated by requirements for strength, durability, time of set and the resistance of the concrete to alkali-silica reaction (ASR).Mixtures should be optimized for strength and durability using appropriate test methods. Concrete mixtures containing slag cement should be proportioned using conventional design. Slag cement should be substituted for Portland cement on a one-to-one basis by mass.
