The developmento of alternative materials for civil construction that possess na ecological faactor is essential to ensure the Sustainability of the sector. The use of recycled aggregates from construction demolition waste as partial replacements for conventional aggregates proves to be na alternative to mitigate the negative effects of activities. This study aims to evaluate the properties acquired by cementitiouns mortars made with fine recycled aggregate from CDW, as well as the results obtained from testes conducted with composities produced with levels of up to 40% substitution of natural aggregate by recycled aggregate. Despite the slight loss of compressive and flexural strength, increased shrinkage and water absorption of the hardened material, it was observed that the substitutuin levels and type of aggregates are determining factors for the improvemente of mortar properties
