Abstract
This article analyzes the existing methods for determining the sulfate resistance of concrete based on cement. The results of the study of concrete resistance by three indicators (weight, density, strength) based on Portland cement modified with polymer additives Primal SM330, DLP2141, DLP2000 in the amount of 3% by weight of cement are obtained. It is shown that a variety of methods for determining the resistance of concrete distort the results and research in this direction remains an urgent topic. The use of concrete based on modified cement allows you to create concrete structures with high strength characteristics in aggressive environments, as well as increase durability.
