Resumo

The influence of preliminary irradiation (3 MeV electron beam) of powdered (≤0.2 mm) synthetic polymers (polyethylene, polypropylene, polyvinyl chloride, polycarbonate, polyethylene terephthalate, or polystyrene) on the compressive strength of cement-sand-polymer compositions has been studied. The surface oxidation of the powders was ensured by irradiation in air or in a water-air mixture. It is shown that the oxidation of the powder in an aqueous medium, as well as the post-radiation alkalization of the powders, contribute to a higher strength of the composites. Oxidation of the powder in air leads to a relative decrease in the strength of the composite due to a higher yield of acid formation.
