Time-dependent behaviour of structural concrete made with recycled coarse aggregates. Creep and shrinkage
HighlightsTime-dependent behaviour of recycled concrete (0%, 20%, 50% and 100%) was analysed.Creep and shrinkage increase as the content of recycled coarse aggregate rises.Internal curing effect influences time-dependent properties of recycled concrete.Proposals to predict shrinkage and creep coefficient of RC were suggested.This leads to the design of RC with the same reliability as conventional concrete.
AbstractThis work is focused on studying the time-dependent properties of recycled concrete, especially shrinkage and creep behaviour. For said purpose, two series of concretes (water to cement ratios of 0.50 and 0.65) were designed with different replacement percentages of recycled coarse aggregate (0%, 20%, 50% and 100%).The experimental program consisted of studying basic properties and time-dependent shrinkage and creep up to 1000days. 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.
