arène granitique

CONT: arène : produit de consistance sableuse, issu de l'altération d'une roche cristalline. Ex. arène granitique.

CONT: ...the use of only one gravel...of the same origin...but semi-crushed so as to attempt to grind the aggregates consisting of arenaceous granite that enters into the composition of the Garone gravel and which are certainly a source of the weakening of the concrete.
