China: Hoffmann Green Cement, which produces clinker-free cement products has been granted a Chinese patent, No. CN 201880079822.X, for its clay-based H-EVA cement. The patent comes a year after a similar patent for its H-P2A binder.
H-EVA is a clinker-free cement that is based on an alkaline ettringitic technology. It uses activated clay and is presented in the form of a powder that can be stored in a silo. With a mechanical strength of up to 60MPa at 28 days, its strong technical performance makes it suitable for all types of concrete applications in buildings and on roads.
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".
