The object of research. Cement concrete modified with 1% plasticizer MuraplastFK-49. Purpose of research. Improvement physic-technical parameters of cement concrete by introducing a modifier Fulvec 100 and selection of rational composition of the modified concrete. Methods. The mobility of the concrete mix was determined according to GOST 10181-2014 "Concrete Mixtures. Test methods"; the average density was determined according to GOST 10181-2014 after 28 days; compressive strength was determined at 28 days according to GOST 10180-2012 "Concrete. Methods of determining strength on test specimens"; water resistance was determined by the method of "wet spots" in accordance with GOST 12730.5-84 "Concrete. Methods of determination of water resistance".IR-spectral methodhas been usedto determinephysic-chemical properties. Results. Rational composition of the concrete mixture modified Muraplast FK-49 and containing additive Fulvec 100 in the amount of 0.12% was carried out, which increases workability, density samples, the compressive strength and water resistance.
