Dec 18, 2010 · Slag cements that are finer than Portland cement will generally cause a slower rate of bleeding than concrete made with ordinary Portland cement. Course slag cements may cause the same or even greater bleed rates and capacities than concrete made with ordinary Portland cement.
During production, Portland cement releases 1 ton of CO2 to the environment when 1 ton of Portland cement is manufactured. The use of slag cement reduces concrete permeability, increases concrete strength, mitigates ASR and sulfate expansion issues, and improves overall concrete durability.
Two major uses of GGBS are in the production of qualityimproved slag cement, namely Portland Blastfurnace cement (PBFC) and highslag blastfurnace cement (HSBFC), with GGBS content ranging typically from 30 to 70% and in the production of readymixed or sitebatched durable concrete. Concrete made with GGBS cement sets more slowly than
Blast furnace slag products have been used successfully in virtually all phases of bridge construction. Projects such as the bridge pictured here can utilize blast furnace slag as a concrete aggregate. Blast furnace slag has been utilized in concrete masonry for many years.
The grade of a ground granulated blastfurnace slag is based on its activity index, which is the ratio of the compressive strength of a mortar cube made with a 50% ground granulated blastfurnace slagcement blend to that of a mortar cube made with a reference cement.
