Plant and technologies: version 4.0
In France, CEM I and CEM II, composed of 85% clinker, still make up 80% of the cements used for construction.
Cement, the number one manufactured product consumed around the world, represents about 5% of worldwide CO₂ emissions and we are in urgent need of a paradigm shift.
With HGCT’s technologies, at equal or greater levels of performance, the carbon footprint of cement (and by extension, concrete) can be reduced by 75%! Concrete formulated with Hoffmann Green Cement Technologies cements have a carbon footprint of 60 kg per m3, as opposed to 250 kg for concrete that has been formulated with traditional cement.
This is equivalent or even lower than the carbon footprint of construction wood, which cannot be sourced locally in France.
Portland Cement / Hoffmann Cement comparison
Comparison of average CO₂ emissions per metric tonne of concrete produced
It’s not just concrete, all compound products such as glues and plasters will be favourably impacted and their carbon footprint reduced by a factor of 4.
New technologies with high levels of performance
HGCT’s new technologies are on par
with traditional cements, offering optimised levels of performance
Reduced carbon footprint
Optimal mechanical strength
Passivation of steels
No chromium VI
Freeze-thaw cycle stability twice as high
New technologies for low-carbon projects
Building a house with Hoffmann Green Cement technologies reduces emissions by 7.2 metric tonnes of CO₂ compared to building with traditional cements. This corresponds to
the amount of CO₂ absorbed by 3.5 ha of forest.
