Popis: This work addresses the reuse of recycled bricks aggregates (RBA), coming from faulty bricks for manufacturing prestressed concrete joists, with different percentages of these recycled aggregates, in building floor slabs. The prestressed joists were manufactured in a local factory with precast facilities and later they were tested to determine their flexural and shear strength. In addition, the set joist-rib-compression layer was also tested in order to assess its flexural and shear strength of the whole set. The results obtained are favourable using RBA percentages up to 35%, but if the set joist-rib-compression layer is considered, using conventional concrete on the rib and the compression layer, this percentage could reach 70%.
