Although concrete based on mineral binders is most commonly used in construction, polymer concrete is on the rise lately. This is due to the fact that polymer concrete allows to expand concrete usage in civil and industrial construction thanks to its properties. However, there is extensive research on including thermoplastic polymer. Construction polymer concrete materials have high compressive strength, as well as atmospheric, cold and chemical resistance, thus resulting in long term lifetime. This paper suggests a technological process of producing concrete based on polyvinyl chloride and lightweight porous aggregate, e. g. fly ash that comes from Vladimir combined heat and power plant (used to run on coal). There are up to 80 thousand tons of this aggregate in stock. It turns out that technological parameters of this process are strongly intertwined with compound. Research indicates that lightweight polymer concrete based on polyvinyl chloride and fly ash can be achieved under certain technological parameters. A new polymer concrete was created as a result of this research having the following properties: density - 800-830 kg/m 3 , compressive strength - 12-13 MPa, impact strength -16-18 kg/m 2 , coefficient of thermal conductivity - 0.16-0.18 Wt/m.K, frost resistance - at least a 100 cycles.
