RESUMO

The use of recycled concrete with substitution of the natural aggregate by recycled aggregate from construction and demolition waste (CDW) is one of the most promising alternatives for reduction of the environmental impact of the construction industry. However, for this solution be applied in wide scale it is necessary that new material can be used in the production of structural elements, which represent the largest portion of the concrete consumption. In this work, the mechanical behaviour of flags and T beams, formed by a precast element and a layer of reinforced concrete, submitted to flexural test. To produce the upper concrete layer recycled aggregates were used. The substitution rates of fine and coarse natural aggregate for recycled ones were 50% and 100%.
