What is Regen?

Regen Ground Granulated Blast furnace Slag (GGBS) is manufactured from blast furnace slag, a by-product of iron-making which makes it highly sustainable. The cementitious properties of blast furnace slag were discovered in the late 19th century and it has been widely used in cement and concrete manufacture for over 100 years. In the UK, GGBS is usually supplied as a separate component for concrete and is added at the concrete mixer. It can replace up to 70 per cent or more of the Portland cement. In British Standards GGBS is referred to as an ‘addition’ and counts fully towards the cement content in concrete.

Regen is a highly sustainable cement substitute. From its low-emission production process to its use in long-life structures, Regen provides many sustainable benefits.

Using Regen as a cement substitute in concrete increases its durability and resistance to deleterious reactions.

Regen changes the appearance of the concrete in which is it used, and is often used to provide a more superior finish than Portland cement-only concrete.
