Corrosion Resistance of Self-Compacting Concrete with a Complex Admixture
Abstract: In the work, the influence of a complex admixture consisting of a viscosity modifier and a superplasticizer on the corrosion resistance of self-compacting concretes 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 admixture 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. Also, there was no incompatibility of the viscosity modifier and superplasticizer used in the composition of the complex admixture, and 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 products and structures used in road construction, which are subject to high requirements for surface quality and do not require additional processing.
