The reinsertion of construction and demolition waste (CDW) in the civil construction sector is a sustainable alternative that has been widely studied. This paper aimed to present the state of the art of the main properties of cementitious mortars made with recycled fine aggregate from CDW. Despite of possible loss in compressive and flexural strength, increased shrinkage and water absorption of the hardened material, as well as increased consistency in the fresh state, it was observed that substitution levels and type of aggregates are decisive for improvement of mortars’ properties.
