On the base of unsaturated polyester resin and nano powder fillers, polymer concrete
(PC) was produced applicative in aggressive underground conditions. The curing agents of the resin for the polyester resin were Akcobalt 6% (cobalt 2-ethylhexanoate mixture) and Akperox A1 (Methyl Ethyl Ketone Peroxide-MEKP). Ultrafine powder was
produced by grinding of a coarse mixture on the PULVERISETTE 7 premium Line
planetary mill by a dry method. Selection and designation of concentrations of
aggressive media - sodium sulfate and sulfuric acid were produced on the base of an
experience in underground constructions. As the criteria for evaluation of suitability of
PC in these environments, the coefficient of corrosion resistance of the material and the diffusion coefficient of liquid media in PC were applied. is the ratio of the retained short-term strength of the material after an effect of aggressive media on its initial short-term strength. Unlike the available literature data on PC obtained by testing of the samples on compression and bending, in this work, the corrosion resistance was evaluated by tensile strained state of the material. was determined on the base of Fick's second law by the sorption method. As a result of exposure in liquid aggressive media of PC during 15-18 months, the values of were determined and the dependence of on time was revealed. An attempt was made to predict the values of for a longer period of operation.
