Greenbloc
Greebloc low CO2 cement alternative is the first cement-free ultra-low carbon concrete block. It promises up to 73% CO2 savings compared to traditional concrete blocks. The product was introduced by CCP, which is part of SigmaRoc plc.
Greenbloc is intended to help reduce the construction industry’s dependency upon cement – the world’s third highest source of manmade CO2 – as a key ingredient in concrete manufacturing. It is a high density, load bearing concrete block made from class 1 aggregates and Cemfree – a totally cement-free alternative to conventional concrete.
Manufactured to BS EN 771 – 3: (2011) and complying with Part E of the Building Regulations for Walls and Floors, Greenbloc is manufactured, stored and placed in the same way as conventional concrete blocks. It is suitable for foundations, load bearing walls, internal leaves of cavity walls and partition walls.
