Hoffmann Green cement becomes first clinker-free cement validated by the CSTB

Hoffmann Green Cement Technologies has announced that its H-UKR cement has become the first clinker-free cement in the world to be validated by the CSTB (Centre Scientifique et Technique du Bâtiment, i.e. Scientific and Technical Center for Building) for structural applications on all types of structures.

Following four years of physical, chemical and mechanical trials, H-UKR cement has benefited from Technical Appraisal (type ‘A’ ATEx) from the CSTB, the public company that guarantees the quality and safety of buildings. This evaluation covers a very large number of buildings from individual homes to tower blocks for various structural applications (floors, shells, beams, columns, etc.) The design of concrete structures based on H-UKR cement is undertaken in accordance with Eurocode 2 and Eurocode 8, design standards recognised in France and Europe.

H-UKR’s ETPM (Évaluation Technique de Produits et Matériaux, i.e. technical evaluation of products and materials) has just been enhanced and more objectifies the sustainability and quality of H-UKR cement by validating the expected lifespan of 100 years, thus paving the way for concrete based on H-UKR cement to be used in civil engineering structures (bridges, tunnels, etc.)

Similarly, this latest version of ETPM introduces new exposure classes (XC1, XC2, XC3, XC4, XF1) hence enabling concrete based on H-UKR cement to be used in both indoor and outdoor structures.

Validated and granted by the CSTB, these evaluations come on top of the many approvals and accreditations already received by the company, thus enabling it to further strengthen its barriers to entry. These evaluations also demonstrate the impetus provided by the strategic partnership deal signed in November facilitating relations between the two entities.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said: “In the midst of ongoing frenetic communication regarding carbon neutrality, Hoffmann Green Cement is as usual endeavouring to back its announcements with verified and evaluated elements. The granting of these evaluations further objectifies the quality of our cement, notably with the awarding of a lifespan of 100 years. In this regard, we would like to thank the CSTB’s teams for drafting this unprecedented technical appraisal and our own teams who are working tirelessly on seeking innovative decarbonised solutions to preserve tomorrow’s world”.

Stéphanie Bondoux, Director of Certification and Accreditation, added: “These evaluations are the result of close collaboration between the CSTB and Hoffmann Green teams. They illustrate the safety, sustainability, lifespan and performances of concrete made with H-UKR cement that will henceforth be seen as a standard technique for insurers and technical controllers for superstructure applications such as columns, beams, shells and slabs. Its use will thus be facilitated. Hoffmann Green will continue the assessment work undertaken on concrete based on H-UKR cement in order to open it up to numerous other applications and hence meet our clients’ needs.”
