Anthropocite : carbon-storing aggregates for concrete

Why integrate carbon-storing aggregates into non-structural concrete ?

Néolithe proposes carbon-storing aggregates derived from the accelerated Fossilization of non-recyclable waste, for those in the building and public works sector wishing to reduce construction-related greenhouse gas emissions.

Called Anthropocite, this new material stores biogenic carbon and replaces up to 20% of natural aggregates extracted from quarries in the composition of non-structural concrete. Néolithe strictly controls its production, enabling it to be distributed to construction sites in a circular economy.

What are the applications of aggregates in concrete ?

Today, these aggregates can be integrated into non-structural concrete.

And tomorrow, thanks to the ATEx currently in progress, other uses will be possible

Today, we integrate our aggregates into various types of concrete. This enables us to produce concretes suitable for uses such as kerbstones, cyclopean concrete, clean concrete, backfill and trench concrete, among others.

Tomorrow, thanks to the ATEx certifications currently in progress, we will be able to extend these applications. For example, these certifications will pave the way for the use of our concretes in industrial and residential paving, foundations, as well as in the manufacture of beams and slabs.

What is an ATEx ?

The Appréciation Technique d’Expérimentation (ATEx) evaluates innovative products or processes not covered by a technical opinion, thus facilitating innovation in the construction sector.
