slag cement questions

Use of slag cement in concrete reduces the environmental impact of concrete by: Reducing greenhouse gas emissions by eliminating approximately one ton of carbon dioxide for each ton of portland cement replaced. Reducing energy consumption, since a ton of slag cement requires nearly 90% less energy to produce than a ton of portland cement

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

Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse gas emissions by more than 40% and lowers the embodied energy of concrete by more than 30%. Another factor is slag cements nearly white color

Jul 07, 2015 The work presented here focuses on the impact of slag composition on the resistance of slag composite cements exposed to sulfates. Such composite systems can be an effective way to provide better sulfate resistance of the binder. However, the differing composition and hydration kinetics between slag and cement results in a change in the phases present and their quantities, the effect of
