(AOF) – Hoffmann Green Cement Technologies, an industrial player committed to decarbonizing the construction sector, today announces the issuance of a Chinese patent for its clay-based 0% clinker H-EVA cement. One year after the issuance of the Chinese patent for its H-P2A binder, Hoffmann Green Cement is stepping up the development of intellectual property in this territory with the obtaining of this patent.
“H-EVA is a 0% clinker cement that is based on an ettringite technology by alkaline route based on activated clay and which comes in the form of a storable powder in a silo”, explains Hoffmann Green Cement Technologies.
With a mechanical resistance of up to 60 Megapascals at 28 days, its solid technical performance allows it to be used for all types of concrete applications in buildings and on roads.
H-EVA is used in particular by the Bouygues Construction group in the context of sites using 0% clinker clay concrete.

The National Union of Quarry and Building Materials Industries (Unicem) indicates that, after an initial downturn in the second quarter, activity continued to deteriorate in the third quarter and recorded a drop in both aggregates (-1.3 %) than on ready-mixed concrete (-0.9%). Over the first nine months of the year, the decline was 2% for the materials business as a whole. Only tiles and bricks manage to show slight increases in activity.
The general outlook is deteriorating and recruitment difficulties and rising costs are the main sources of concern. Furthermore, Unicem underlines the difficulties in implementing the projects. The production of materials could decline this year by 3% for ready-mixed concrete (BPE) and 4% for aggregates.
