Fast set GGBS Binder

Abstract

To reduce CO₂ emission producing Ordinary Portland cement (every ton of Portland cement accounts for roughly 850 kg CO₂) the use of supplementary cementing materials (SCM's) are becoming todays standard in the cement and construction industry.

Although some SCMs are used on their own, most of them are used in combination with Portland cement clinker.

Aim was to accelerate the setting time of a pure GGBS binder and improve its early strength development. From different publications we learned that fast setting cements contain C₁₁A₇. CAF₂ similar to the phases calculated from our Type II GGBS.
