UK: Contractors poured 736m³ of cement-free concrete in an 11-hour continuous pour at the Hurst substation tunnel drive shaft of the London Power Tunnels project on 11 May 2023. Construction Index News has reported that Capital Concrete supplied the concrete. It uses a formula developed by Earth Friendly Concrete to replace 100% of cement with fly ash and ground granulated blast furnace slag (GGBFS) in the presence of an activator and admix solution. The supplier said that the concrete will reduce CO₂ emissions by 64% compared with ordinary Portland cement (OPC), corresponding to 111kg/m³ of concrete.

UK: Ready-mix concrete (RMX) supplier Capital Concrete has dedicated two 60t silos at its London plants to supply Cemfree, a low carbon concrete made using ground blast furnace slag (GGBS) made by DB Group. It is the only RMX supplier in London supplying the product in this way.

“We’ve seen customer interest pick up recently, interest which is clearly linked to the growing importance of environmental considerations in construction build designs. Capital Concrete is now a leading supplier of Cemfree in the London area and we’re able to supply high volumes of this product anywhere in the London market,” said Luke Smith, the managing director of Capital Concrete.
