    Heidelberg low carbon concrete at 33–35 Piccadilly: mix design notes for engineers

    First reported on The Construction Index

    30 Second Briefing

    Heidelberg has supplied low carbon concrete, using carbon capture–decarbonised cement and GGBS, to Realtime Civil Engineering and Kier for the Crown Estate’s 33–35 Piccadilly redevelopment in central London. The mix design replaces a significant portion of Portland clinker with ground granulated blast-furnace slag, cutting embodied CO₂ compared with conventional CEM I concrete while maintaining structural performance suitable for a high-end commercial building. For contractors and designers, the project shows practical deployment of carbon capture–enabled binders on a constrained urban site with demanding specification control.

    Technical Brief

    • GGBS is incorporated as a latent hydraulic binder, activated by the remaining Portland clinker.
    • Pumping distances and pressures are controlled to avoid segregation in the higher-fines, slag-rich mixes.
    • Quality control focuses on heat of hydration, setting time and workability retention for urban pours.
    • Durability performance is critical for a high-end commercial façade line directly exposed to urban pollutants.

    Our Take

    In our Materials coverage, Heidelberg and Heidelberg Materials UK recur frequently, with recent pieces on Westdown quarry and North Yorkshire asphalt, signalling a push to lock in both upstream aggregates and downstream product outlets in the United Kingdom.

    The use of low‑carbon concrete at 33‑35 Piccadilly aligns with Heidelberg’s parallel deployment of evoZero cement in Marley’s Edgemere 2.0 roof tiles, suggesting the company is actively seeding multiple UK product lines that can absorb its captured and ‘banked’ CO₂ volumes.

    Pairing a prestige London project with the Crown Estate as client gives Heidelberg a high‑visibility reference for its lower‑carbon mixes, which is likely to help when bidding for other sustainability‑tagged projects in our database, especially in dense urban settings where embodied carbon is under scrutiny.

    Paladin rare earth recycling expansion: supply-chain takeaways for engineers

    Rare earth recycler Paladin EnviroTech is investing over US$5 million to expand its Ohio recovery facility from 40 to 150 tonnes per year by Q3 next year, targeting end-of-life hard drives, EV motors, generators, MRI machines and wind turbines containing neodymium, praseodymium, terbium and dysprosium (up to ~16% Dy in MRI magnets). Working with Western Digital and Critical Materials Recycling, Paladin uses a non-acidic selective leaching process achieving 97–98% rare earth recovery and about 90% total value recovery, feeding mixed rare earth oxides back into Western magnet supply chains.

    Breedon’s new CEO from 2027: strategic implications for materials project teams

    Breedon has appointed current chief financial officer James Brotherton as its next CEO from 1 January 2027, succeeding Rob Wood after a 12-year tenure with the construction materials group. Brotherton has been CFO since 2021 and co-developed Breedon’s “expand and improve” strategy, which underpinned its expansion into the US market and transfer to the London Stock Exchange’s main market. Wood, who became CEO in 2021, will step down from the board at end-2026 but remain an employee to support the leadership transition until September 2027.

    Chryso–Ecocem low‑carbon cement system: mix design notes for concrete engineers

    Saint-Gobain’s Chryso and Ecocem have launched a combined low‑carbon system pairing Ecocem ACT cement, which cuts cement emissions by up to 70%, with Chryso’s new superplasticiser EnviroMix 3150 ACT, formulated for this binder chemistry. The admixture–cement combination enables concrete mix designs achieving over 50% carbon footprint reduction, meeting GWR5 and above, while maintaining high flowability, low viscosity at low water–cement ratios, and workability retention beyond 90 minutes without segregation. On the former John Lewis HQ refurbishment in London, around 1,300 m³ of C20/25 and C30/37 ACT concrete is being pumped using EnviroMix 3150 ACT to validate performance under site conditions.
