Hoffmann Green, GCC and Néolithe combine their expertise to produce concrete with a very low carbon footprint
In Marseilles, the three partners have just poured an invert for a very low carbon footprint fuel loading slab for RTM (Régie des Transports Métropolitains). The H-UKR concrete used incorporates 20% aggregate obtained by accelerated fossilization of non-recyclable construction site waste manufactured by Néolithe. This invert will be used by GCC’s engineering and technical department to take precise measurements in terms of decarbonation and durability, compared with the use of conventional concrete.
While the use of this concrete changes nothing in terms of processing, it changes everything in terms of carbon footprint: 62 kg CO2eq/m3 for the H-UKR + 20% Anthropocite formulation, compared with 167 kg for traditional CEM II/A concrete!
GCC cast two identical slabs for comparison purposes:
- A traditionally formulated concrete slab
- A slab with 370 kg/m3 of Hoffmann 0% decarbonated clinker cement, combined with aggregates derived from the fossilization of Neolith waste (20%) in addition to 80% standard aggregates.
“Since 2020, our collaboration with GCC has gone from strength to strength, and this project is striking proof of that! Together, with visionary partners like Néolithe and RTM, we are determined to revolutionize construction by decarbonizing it. Thanks to Néolithe’s innovative recycled aggregates, our ambition is clear: to supply the world’s most carbon-free concrete today,” says Julien Blanchard, Chairman of the Management Board of Hoffmann Green.
