<p>A process for producing building materials, such as asphalt, cement, concrete, mortar, or plaster board from liquid paint sludge containing water and paint solids produced from overspray in commercial paint booth operations is disclosed, wherein the process comprises mixing liquid paint sludge with one or more building material ingredients to produce a final building material; and allowing the mixture to cure, thereby producing a final building material, wherein the liquid paint sludge is used directly as a hydrating agent for the final building material. Optionally, however, additional water can be added to provide the desired water to the building material ratio.</p> |
