TL;DR
This study explores using paint booth waste as a substitute for concrete aggregates, finding that up to 20% substitution yields strong, non-toxic blocks.
Contribution
The novel use of paint booth waste with varied aggregate sizes in concrete blocks is evaluated for mechanical and environmental performance.
Findings
Concrete blocks with 10-20% PBW substitution showed compressive strengths over 35 MPa.
PBW incorporation prevented metal leaching, ensuring environmental safety.
Higher PBW levels increased porosity and water absorption in concrete blocks.
Abstract
Inadequate disposal of hazardous waste results risks to the environment and human health. Although the use of hazardous waste in new processes and/or products has received limited attention in the literature, there is still significant potential to be investigated. Reducing the usage of natural resources and waste management are important for sustainable practices during concrete production. This study investigated the mechanical and leaching behavior of paint booth waste (PBW) as a partial substitute (10, 20, 30 and 40%) of coarse aggregate in concrete mixtures for the manufacture of interlocking blocks. A sample of PBW used in this research differs from those in the literature due to its granulometry characterized by aggregates of different sizes. Concrete consistency, compressive strength, water absorption, X-ray diffraction, scanning electron microscopy, and leaching tests were…
