Objective: This work was developed seeking an alternative method for the manufacture of blocks interlocked with sustainable features. Methodology: For the manufacture of these blocks, the technical feasibility of using the ceramic waste from construction and demolition (WCD) was studied experimentally in partial replacement to natural fine aggregate (sand), for it has been becoming increasingly scarce, relevant to the exhaustion of deposits, as well as the limitations of environmental agencies for the extraction of raw materials. The work also aims at recycling and reusing disposable waste on the environment, showing the whole process of characterization of materials, detailing every step of production, since the collection up to the stage of household use as a fine aggregate and all the percentages of replacements (0%, 10%, 20%, 30%) to natural aggregate, maintaining the same factor water/cement. Tests were performed (dimensional analysis, absorption and resistance to compression). Results: The use of ceramic waste in the manufacture of interlocked blocks reduces the moisture content and increases the resistance to each gross percentage added. Conclusion: It ensures a durable material, sustainable to reuse the waste from construction and demolition (WCD) as household, thus minimizing the use of conventional aggregate and reducing the cost of the final material. Descriptors: Floor. Block. Sustainability. Resistance.
