Mechanically Resistant Composite Material Using Optimal Amount of Pre-treated Hazardous Waste

The utilisation of a relatively high amount of hazardous waste such as neutralising sludge (NS), which is a by-product of galvanic metal plating, as filler in a mechanically resistant composite material with an epoxy matrix, appears to be a progressive approach for improving the environment aspects. Polymer composites containing a filler of pure finely-ground silica sand – silica flour (SF) and fine foam glass waste (FGW) with a particle size of less than 200 μm were used for comparison of the achieved mechanical parameters. Considering the required consistency of the composite, related to its intended application in practice, 40% of the epoxy resin fillings was tested. It was shown that the developed, mechanically-resistant composite exhibits very high impact and wear resistance. Based on the assessment of the results obtained, it was found that the composite containing pre-treated hazardous waste achieved only 20% lower compressive strength than the reference composite, which comprised only primary raw materials. It is thus claimed that specific pre-treated hazardous waste can be effectively used for the preparation of special repairing composite material, and also in areas with a significant mechanical load.
