ECOPact comes with a range of formulae offering different levels of carbon dioxide savings, from 30% to 70% compared to standard (CEM I) concrete.
ECOPact Prime is described as an engineered low carbon concrete using higher blends of cements using ground granulated blast furnace slag (GGBS) and FlyAsh substitutes. This delivers between 50-70% CO2 reduction compared to a standard concrete (CEM I) mix, it is claimed.
ECOPact Max uses cement alternatives such as geopolymers and alkaline activators to reduce CO2 content by at least 70%.
Aggregate Industries promises to give the extra money paid by customers with a conscience to its offsetting partner, Circular Ecology, who will then fund projects such as tree planting, clean water projects and investment in renewable energy.
Chief executive Guy Edwards said: “We are delighted to launch the ECOPact range of low carbon concretes in the UK, and we cannot wait for our customers to reap the benefits.”
