Eco Cement

Concrete was always considered not Eco friendly. But now there is a eco-friendly cement, Ecocem Ireland is an independent, specialist producer of GGBS (Ground Granulated Blastfurnace Slag) cement. GBBS cement is manufactured from an industrial by-product (blastfurnace slag) - there is no extraction of new materials. The production of CO2 in manufacturing GGBS is approximately 60kg per tonne (from the electricity and gas consumed) and there are zero CO2 and NOx (oxides of nitrogen) emissions.
1 ton of Portland Cement produces 960 kg of CO2 .

1 ton of GGBS produces 60 kg CO2 some difference.
