Abstract: The concrete and reinforced concrete of hydraulic structures are constantly affected by internal and external factors. With the rapid improvement of the construction sector chemical materials are being used in concrete more and more often in order that structures should withstand various internal and external factors. The usage of polymer modified concrete as building material is rare due to relatively expensive polymer admixtures. Therefore, sometimes cheaper nontraditional materials (concrete primers), which are made on acrylic base, are used in local building as well. During the research three different polymer admixtures were used to modify C12/15 class concrete. The first admixture (A) was the traditional admixture designed for concrete to improve the strength and longevity. The second (B) and the third (C) admixtures were used as nontraditional. The test results confirmed that better properties had polymer modified concrete which was cured in air. Using professional polymer admixture we can reach C16/20 concrete class. To use the non-professional polymers for concrete modification is not recommended, because one from the two admixtures, used in tests, strongly disimprove the properties of concrete. Other admixtures only in some cases had the positive effect on concrete
