Deformation recovery of reinforced concrete beams made with recycled coarse aggregates

The purpose of this research is to analyse the long-term deformations reinforced concrete beams made recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For said purpose, three loading stages were carried out: firstly, sustained load for 1300 days, secondly, unloading recovery where registered over a one year period, lastly, testing up failure in order effect on pre-cracked members. results led analysis under load, as well those produced after removing performance members, while identifying terms plastic deformation, recoverability stiffness, also structural design.
