Le comportement des bétons incluant des granulats recycleés

ABSTRACT At the present in France, only a few part of demolition waste (10 to 15 %) are recycled as aggregates; owing to economical, political and ecological pressures these last few years, the percentage of the recycled materials have to change. The recycled aggregates coming from demolition wastes find prospects in road construction, just like most wastes, but their use in hydraulic concrete is just being implemented. This paper presents the basic properties of concrete with recycled aggregates produced industrially. The fresh concrete behaviour and the hardened concrete performances are being carried out.
