Self-compacting concrete with recycled concrete aggregate: Study of the long-term properties

•Long-term behavior of self-compacting concrete is investigated.•Coarse and fine recycled concrete aggregates are used in self-compacting concrete.•Self-compacting characteristics are maintained when recycled aggregates are used.•Recycled aggregates of good quality promote high mechanical properties.•Creep behavior is influenced by the content and assortment of recycled aggregates. This paper investigates the shrinkage and creep of self-compacting concrete prepared with coarse and fine recycled concrete aggregates (up to 40% of total amount of aggregates). Physical properties and porosity measurements are studied and related to the mechanical properties. Results highlight that self-compacting characteristics are maintained when recycled aggregates are utilized and their good quality promotes high mechanical properties. Creep behavior and pores size distributions are more influenced by the content and assortment of recycled aggregates, although their effect is more limited compared to what occurs in traditional concrete with recycled aggregates.
