Heidelberg delivers low-carbon concrete featuring carbon-capture decarbonised cement and GGBS to Crown Estate project in Piccadilly.
Heidelberg has supplied low-carbon concrete for use on the Crown Estate's 33-35 Piccadilly development in London. The materials were delivered to main contractor Kier and civil engineering firm Realtime Civil Engineering for structural works on the high-profile site.
The concrete supplied for the scheme incorporates cement decarbonised through carbon capture technology, alongside Ground Granulated Blast-furnace Slag (GGBS). By replacing standard Portland cement with recycled by-products and capturing carbon during production, the material significantly reduces the embodied carbon footprint of the structural elements on site.
While carbon-captured concrete is currently specified on major commercial and civil projects rather than over the counter at local merchant branches, its growing adoption signals how building material supply chains are evolving. Groundworkers and general builders purchasing bagged or ready-mix concrete from merchants like Travis Perkins or Jewson will see higher proportions of GGBS and alternative binders in standard mixes over time. Tradespeople pricing works subject to strict site sustainability metrics should ensure they understand cured setting times and handling requirements for alternative concrete mixes, as low-carbon formulations can behave differently in cold conditions compared to traditional mixes.
The deployment of low-carbon building materials on major commercial sites indicates that sustainable material standards will continue to filter down through merchant networks and regional supply chains across the UK.
