Néolithe has worked with the CSTB to carry out its first assessment of its aggregate

Drawing on its network of expertise, CSTB assessed Anthropocite’s intrinsic characteristics. Once this collegial expertise had been gathered, CSTB issued an evaluation in the form of a Technical Evaluation of Products and Materials (ETPM). This evaluation mainly constitutes the common working basis needed by construction process evaluation bodies.

The assessment did not reveal any incompatibilities that would rule out the intended use. It was based on the assumption that Anthropocite aggregate would be used to manufacture concrete using cement complying with standard NF EN 197-1 of type CEM I, CEM II/A, CEM II/C, CEM III/A, CEM III/B or CSS complying with standard NF EN 15743 for the test results presented, and a substitution rate for Anthropocite aggregate of up to 10% of the chippings mass and for non-structural, non-reinforced use, such as clean concrete, trench concrete, kerbstone concrete and non-reinforced fill concrete.

This evaluation, obtained following a voluntary process by Néolithe, is the basis for assessing Anthropocite’s suitability and paving the way for new uses. Currently used by professionals for non-structural concretes, Néolithe aims to extend the uses of this new material to other types of concrete, including structural concretes, and in increasingly higher percentages, with a short-term objective of 30% substitution of traditional aggregates.
