  • Descrição: Utilization possibilities of solidified fractions of industrial hazardous waste obtained by mixing with inert materials in construction were investigated. Waste mineral oils, water-hydrocarbon emulsions mixture, and waste filter cakes from the physico-chemical treatment of wastewater generated by washing of patterned rollers for a printing machine, were used as models of industrial hazardous waste in the solidification process. Investigation comprised preparation of concrete and asphalt mixtures for further testing. The solidified powder was analyzed regarding the granulometric composition, while the obtained concrete samples were further subjected to compressive strength determination, whereas the asphalt mixtures were tested in the context of potential waterproofing materials. According to the obtained leaching test results, all the samples met the required conditions for further application. Compressive strength test results were in the range of 8.7-22.6 MPa. Still, the measured compressive strength values were lower than expected, which is explained using solidified powder fractions of smaller grain size. According to the results, it can be concluded that the investigated mixtures cannot be used for structural building elements, but their usage is recommended for elements such as pavements, roadside, path cubes, concrete haberdashery, etc. Asphalt mixtures showed acceptable properties in terms of mechanical, durability, and waterproofing tests.
