Porosity of recycled concrete with substitution of ...

Aug 01, 2002  1. Introduction. Current studies of recycled concrete (RC), with partial substitution of natural aggregate (NA) by recycled aggregate originating from concrete (RAC), promise a feasible path for its application, thus satisfying a need, saving energy, improving environmental conditions and providing a solution for the 200 million tons/year of construction waste generated in the EU , , , , , , .
