    Versarien on the brink: implications for graphene concrete projects and design teams

    Versarien on the brink: implications for graphene concrete projects and design teams

    First reported on The Construction Index

    30 Second Briefing

    Versarien plc, developer of the Cementene graphene admixture, has filed a notice of intention to appoint Leonard Curtis as administrators, triggering a two-week protection period and suspension of AIM share trading while creditors consider options. Cementene was shown by Banagher Precast Concrete in 2023 to enable a 20% reduction in ordinary Portland cement in a standard precast mix, and Versarien had a collaboration agreement with Balfour Beatty to develop new concrete materials. The company has also supplied graphene technology to HS2 trials with the Skanska Costain Strabag JV and participates in National Highways’ Roads Research Alliance and the Digital Roads of the Future project.

    Technical Brief

    • Board explicitly states ongoing operations are contingent on continued creditor support during this protection window.

    Our Take

    With only a handful of Materials stories in our coverage, a UK-focused case like Versarien plc’s Cementene work with Banagher Precast Concrete stands out as one of the few that directly targets embodied carbon in structural concrete rather than operational emissions.

    A demonstrated 20% ordinary Portland cement reduction in precast mixes is technically significant enough to interest UK infrastructure clients such as HS2’s SCS JV and National Highways consortia, but commercial fragility at Versarien raises the risk that early-stage trials on projects like Digital Roads of the Future stall before wider specification or standardisation can occur.

    For UK contractors such as Balfour Beatty and Skanska Costain Strabag JV, supplier distress in niche admixtures like Cementene underlines the need for dual-sourcing or in-house materials R&D if they intend to lock in low-clinker concrete solutions at programme scale.

    Martin Engineering N2 ACI system: control and reliability notes for kiln engineers

    Martin Engineering has introduced the N2 Air Cannon Intelligence (ACI) System, turning conventional air cannons in cement kilns and other high-temperature process lines into monitored, connected assets. Wireless N2 sensors mounted on each cannon feed real-time pressure, firing and cycle data to a central gateway, allowing operators to detect misfires, blocked valves and suboptimal firing sequences without manual inspection. For materials handling and process engineers, this enables tighter control of build-up removal on preheaters, riser ducts and clinker coolers, reducing unplanned shutdowns and compressed air waste.

    Trelleborg polyurethane seals for fluid power: retrofit notes for mining engineers

    Trelleborg has launched a new inch-size polyurethane sealing line for light-, medium- and heavy-duty hydraulic cylinders, covering piston, rod and buffer seals plus wipers for linear hydraulic applications. The Zurcon RU9 and Zurcon U-Cup RU9 profiles are engineered to retrofit directly into common American groove sizes in OEM and replacement equipment, targeting mining and other mobile hydraulics. For maintenance and design engineers, the inch-based range simplifies specifying high-performance PU seals without re-machining existing cylinder hardware.

    Holcim starts imports at Tilbury: circular cement plant design notes for engineers

    Holcim’s Tilbury Cement Works has begun importing cementitious materials via a deep‑water berth at the Port of Tilbury, using a new ship‑to‑shore conveyor, enclosed belt conveyors and the UK’s first 30,000‑tonne cement dome silo to feed six loading heads and five weighbridges. A vertical roller mill due in late 2026 will grind GBFS and recycled concrete fines to produce GGBFS and blended cements, with ECOPlanet and ECOPlanet with ECOCycle products scheduled for early 2027. The site has been built using circular practices, reusing 25,000m³ of crushed concrete and 10,000 tonnes of reclaimed asphalt.
