Annotation: In the work, the influence of a complex additive consisting of a viscosity modifier and a superplasticizer on the resistance of self-compacting concrete to the second type of corrosion was studied. The ash and slag mixture of the Zuevskaya TPP was used as a mineral filler. It has been established that the use of an ash-and-slag mixture as a mineral filler and the introduction of a complex additive into the composition of self-compacting concretes increases their strength characteristics both in the early and later periods of hardening. In addition, the developed concrete compositions meet the requirements for changing the strength characteristics after keeping the samples in an aggressive environment. There was no incompatibility of the viscosity modifier and superplasticizer used in the composition of the complex additive, as well as its negative effect on the corrosion resistance of self-compacting concrete. Therefore, it can be recommended to use the developed concrete compositions in the production of a wide range of products and structures, which are subject to high requirements for surface quality and do not require additional processing.
Keywords: self-compacting concrete, strength, viscosity modifier, superplasticizer, ash and slag mixture, corrosion resistance, second type corrosion.
