Hoffmann Green Cement announces the granting of the H-EVA patent in China, its clinker-free cement based on activated clay

PRESS RELEASE - March 2023

Chaillé-sous-les-Ormeaux, (France), March 6, 2023 - 8:00 am CET: Hoffmann Green Cement Technologies (ISIN: FR0013451044, Ticker: ALHGR) ("Hoffmann Green Cement" or the "Company"), an industrial player committed to decarbonizing the construction sector that designs and distributes innovative clinker-free cement, announces today the granting of a Chinese patent for its clay-based H-EVA cement.

One year after the granting of the Chinese patent for its H-P2A binder, Hoffmann Green Cement is further developing its intellectual property in this territory with the granting of a patent for its 0% clinker H-EVA cement.

After more than three years of analysis, the H-EVA patent has been validated by the Chinese Patent Office under the number CN 201880079822.X.

As a reminder, H-EVA is a 0% clinker cement based on an alkaline ettringitic technology based on activated clay and which is presented in the form of a powder that can be stored in a silo. With a mechanical strength of up to 60 Megapascal at 28 days, its strong technical performance makes it suitable for all types of concrete applications in buildings and on roads. H-EVA is notably used by the Bouygues Construction group in the context of 0% clinker clay concrete projects.

This confirms once again our technological lead and the relevance of our lowcarbon solutions".
