The manufacture of conventional cement is very polluting. In particular, it requires a lot of energy to produce clinker, the main component of cement. To reduce its carbon footprint by 80% by 2050, the cement industry must therefore innovate.
Hoffmann Green is fully committed to this mission. Decarbonated cement is already an accessible reality. We have developed 3 types of cements without clinker, for a significant reduction in CO2 emissions. Today’s key challenge is to reduce the environmental impact of future construction.
In our state-of-the-art plant, we manufacture 3 carbon-free cements for all technical applications in sustainable construction: stairs, curbs, slabs, prefabricated walls, drainage paving stones, foundations or concrete blocks.
These 3 solutions are:
These innovative processes do not involve firing, but cold chemical reactions between materials by means of activators. The materials used are by-products from other industries: metakaolin clay, gypsum, blast furnace slag, sodium metasilicate.
Our cements have a carbon footprint divided by up to 5. This ecological performance goes hand in hand with technical performance that is equivalent, if not better, than that of conventional cements:
The main factor responsible for CO2 and greenhouse gas (GHG) emissions during the manufacture of concrete is cement. It is used as a hydraulic binder between aggregates.
Our cements make it possible to obtain a low-carbon concrete, thanks to the absence of clinker, 95% of which is made of a conventional Portland cement (CEM I) and comes from a highly emissive process (quarrying, transport, fossil fuel firing, grinding).
The use of Hoffmann Green cements is interesting for engineering concretes (self-placing, special foundations, screeds), prefabrication and even waste inerting.
Hoffmann Green cements contribute to a significant reduction in the carbon footprint of your construction, through :
Thanks to its innovations, Hoffman Green strives to preserve the environment as much as possible (by reducing the carbon footprint) while guaranteeing high-performance concretes for eco-construction.
