摘要: Abstract This research aims at analysing the mechanical performance of concrete with recycled aggregates (RA) from construction and demolition waste (CDW) various locations in Portugal. First characteristics (natural recycled) used production were thoroughly analysed. The composition RA was determined several physical chemical tests performed. In order to evaluate concrete, compressive strength (in cubes cylinders), splitting tensile strength, modulus elasticity abrasion resistance Concrete mixes CDW recycling plants evaluated, understand influence that RA's collection point, consequently their composition, has on produced. analysis allowed concluding use worsens most properties tested, especially when fine are used. On other hand, there an increase coarse global terms, this type aggregates, limited contents, is viable a viewpoint.
