Inadequate disposal of hazardous waste results risks to the environment and human health. Although use in new processes and/or products has received limited attention literature, there is still significant potential be investigated. Reducing usage natural resources management are important for sustainable practices during concrete production. This study investigated mechanical leaching behavior paint booth (PBW) as a partial substitute (10, 20, 30 40%) coarse aggregate mixtures manufacture interlocking blocks. A sample PBW used this research differs from those literature due its granulometry characterized by aggregates different sizes. Concrete consistency, compressive strength, water absorption, X-ray diffraction, scanning electron microscopy, tests were carried out. The did not influence consistency fresh state concrete. blocks with smaller substitutions (10 20%) presented denser structures greater strengths, surpassing 35 MPa after 28 days. Higher levels resulted more porous absorption. concrete-PBW showed no metal toxicity, i.e., incorporation construction material avoided leaching. up 20% demonstrated satisfactory environmental performance.
