Hoffmann Green Cement announces 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.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said, "Following the granting of a first patent for our H-P2A technology, we are delighted to announce the strengthening of our intellectual property in the Chinese market with the granting of a patent for our clay-based H-EVA cement. This confirms once again our technological lead and the relevance of our low-carbon solutions”.
