Ground Granualated Blast Furnace Slag

Slag is a by-product from steel plants obtained from blast furnaces, during the separation of iron from iron ore. The process involves cooling of the slag through high-pressure water jets, which enables the formation of granular particles. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder, which is called GGBS.

According to the EPD data, what sets GGBS apart from other building material is that its global warming potential is at 60.21 kg CO₂ equivalent, which is among the lowest in the industry.
