Road Concretes Modified with Waste from Epoxy Resin Production
Abstract: Using special methods of physicochemical analysis for determining the chemical and mineralogical composition of water-organic emulsions (epoxy resin production waste), requirements have been formulated for oligomer-polymer waste from the production of epoxy resins – effective modifiers of the surface of mineral powders of concrete mixtures prepared on organic binders of coke-chemical production (coal road tars) and oil refining (petroleum road bitumens). Using the example of tar-polymer concrete, in which coal tar road tar grade D-5 with a viscosity of С3010 = 180 s is modified with 2 % by weight of polyvinyl chloride screenings, and dolomite mineral powder with a specific surface area of
635 m2/kg is surface-activated by oligomer-polymer waste from the production of epoxy resins with an oligomer content of 19–24 wt. % and polymers of 2–15 wt. % it was established that activation of the dolomite dust surface by oligomer-polymer waste from the production of epoxy resins leads to significant strengthening of the interphase contact «organic binder – surface of mineral powder» at a two percent mass concentration of oligomer-polymer waste. This leads to a significant increase in the compressive strength and the coefficient of long-term water resistance of tar polymer concrete.
Keywords: tar polymer concrete, oligomer-polymer waste from the production of epoxy resins, special methods of physical and chemical analysis, complex-modified tar concretes, operational properties of road tar polymer concrete.
