Time-dependent behaviour of structural concrete made with recycled coarse aggregates. Creep and shrinkage

The experimental program consisted of studying basic properties and time-dependent shrinkage and creep up to 1000 days. The results showed that shrinkage and creep strains increase with the replacement percentage, and the use of pre-saturated recycled aggregates leads to different time-dependent development of shrinkage and creep strains at early ages due to the internal curing effect. Finally, a function to predict recycled concrete shrinkage and creep coefficients was adjusted according to the content of recycled aggregates and concrete age.
