How GGBS is used and its typical substitution rates

How is GGBS used?

GGBS (Ground Granulated Blastfurnace Slag) is used all over the world as a direct replacement for Portland cement. It is added to the concrete mixer along with ordinary cement, aggregates and water.

The normal ratios and proportions of aggregates and water to cementitious materia......

Concrete made with slag improves resistance to fire damage

Better performance of slag concrete exposing to high temperatures

Concrete made with GGBS cement is much better than concrete made with 100% OPC at maintaining its compressive strength when exposed to high temperatures.

OPC specimens heated to 400 °C or above have been shown to exhibit severe crac......
