The Civil Construction Industry is an important sector of the Brazilian economy, in recent years it has been showing an increase in participation in the Gross Domestic Product (GDP). However, even with the development presented, the waste of materials and the increasing generation of solid waste from construction and demolition (CDW) cause great impacts to the environment. In this sense, this work aims to analyze the replacement of natural small aggregates by recycled small aggregates from construction and demolition waste for the production of recycled concrete. This work makes a comparison between the properties of conventional concrete with the properties of recycled concrete, both produced in the laboratory, through analysis in the fresh (workability) and in the hardened state (compressive strength, tensile strength and water absorption) of traces with 100% replacement of the conventional fine fraction by the recycled fine from residues of concrete specimens. The results show that it is possible to make the replacement of 100% of the natural kids aggregates by the recycled kids aggregates in structural concrete with a reduction of only 6% in compressive strength. However, a detailed study of the dosage and feasibility of these materials should be carried out for use in construction. Thus, there is a huge field of possibilities for the use of these materials that needs to be explored.
