description: The subject of the study is the sulfate resistance of concrete.
Object of study - concrete mixes and concretes.
Objective: To develop the composition and study the properties of sulfate-resistant concrete without the use of sulfate-resistant cement.
In this paper, we consider the possibility of using additives as an additional raw material resource for producing sulfate-resistant concrete and improving the physicochemical properties of concrete in order to ensure corrosion resistance in aggressive environments and seawater.
In the course of the work, laboratory tests were conducted to determine the possibility of using additives in the composition of concrete operating in an environment with a high content of sulfates. Processing of the obtained results was carried out in accordance with GOST R 56687-2015.
Based on the tests carried out, general conclusions are formulated about the possibility of using mineral additives in the composition of marine hydraulic concrete.
The novelty of the work lies in the determination of sulfate resistance of concrete using additives in accordance with GOST R 56687-2015 and in the study of the problems and reasons for the fear of designers to use additives in the construction of reinforced concrete structures.
The results will allow more reasonably use modern materials (additives) in the construction and construction of reinforced concrete elements of hydraulic structures.
