Résumé
[EN] One approach to tackle the problems created by the vast amounts of construction and
demolition waste (CDW) generated worldwide while at the same time lengthening concrete durability
and service life is to foster the use of recycled aggregate (RA) rather than natural aggregate (NA).
This article discusses the use of polyhydroxyalkanoates (PHAs)-producing mixed microbial cultures
(MMCs) to treat the surface of recycled concrete with a view to increase its resistance to water-
mediated deterioration. The microorganisms were cultured in a minimal medium using waste
pinewood bio-oil as a carbon source. Post-application variations in substrate permeability were
determined with the water drop absorption and penetration by water under pressure tests. The
significant reduction in water absorption recorded reveals that this bioproduct is a promising surface
treatment for recycled concrete.
