It is well known the fact that the Civil Engineering sector is a great generator of pollution. Considering that, the search for sustainable methods and materials becomes even more necessary for the sector. In addition, it is also necessary to find different ways to reutilize materials and residues. Many studies relate to the incorporation of these residues in the production of concrete blocks in structural or sealing masonry. In this project, a research on previous studies of construction residues was done, to evaluate the resistance of blocks made out of these residues, analyzing compression and absorption. These properties, as well as the water/cement proportion, were analyzed through regression analysis, obtaining a determination coefficient of 0,1955 (moderate) for the resistance to compression and water absorption, and 0,0031 (very low) between the resistance and the relation water/cement. A cluster analysis was done on the blocks properties, determining 6 groups with similarities, in which we can observe the tendency of blocks with bigger resistance to have less water absorption, and vice versa. The conclusion was that the incorporation of residues shows itself viable in most of the analyzed blocks, with the need to a careful analysis of properties and characteristics of the utilized residues, aiming to ensure how it can affect the physical and mechanical properties of blocks.
