CCP expands cement-free Greenbloc range

CCP Building Products, the SigmaRoc owned precast concrete manufacturer, has expanded on being the UK’s first Cement Free Ultra-low Carbon Concrete Building Block, utilising their Greenbloc technology across their complete product portfolio.

Tthe Greenbloc range is now be available in three tiers of carbon saving with the launch of Greenbloc Standard, Premium and Ultra variants. Manufactured to BSEN 771-3 and providing the same quality, compressive strength and durability as traditional concrete blocks each variant of Greenbloc will provide increasing original Portland cement (OPC) substitution and therefore ever increasing benefit of lower embodied CO2 (‘CO2e’). As standard, customers have benefitted from product with 30% OPC substituted since the beginning of 2022 and this has now been increased to 50% at no extra cost to the customer. The Premium and Ultra variants will provide 80% and 100% OPC substitution respectively.
Greenbloc Ultra is completely cement free, provides on average a significant net reduction in eCO2 of 77% per concrete block, resulting in the following specific decreases:
• an average reduction of 1.1kg of eCO2 per concrete block;
• an average reduction of 2.7 tonnes of eCO2 per average semi-detached house;
• these average reductions are equivalent to the CO2 emitted by an average household’s electricity consumption for four years.
