Hoffmann Green Cement says it has been granted a patent in China for its H-EVA clinker-free cement based on activated clay.
One year after the granting of the Chinese patent for its H-P2A binder, France-based Hoffmann Green Cement says that it is further developing its intellectual property in this territory with the granting of the latest patent.
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.
H-EVA is a 0% clinker cement based on an alkaline ettringitic technology and activated clay, 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, commented: “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.”
