Abstract: The paper investigates the effect of a complex additive consisting of a viscosity modifier and a superplasticizer on the rheological properties of self-compacting concrete mixtures and the physical and mechanical properties of self-compacting concrete. The ash and slag mixture of Zuevskaya TPP was used as a mineral filler. All studied compositions of concrete mixes had rather high values of mobility. 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 the strength characteristics both in the early and later periods of hardening. Consequently, no incompatibility of the used viscosity modifier and superplasticizer and their joint negative effect on the studied properties of self-compacting concrete mixtures and concretes was noted. It is possible to recommend the use of self-compacting concrete mixtures of the studied compositions for the manufacture of unreinforced or low-reinforced concrete structures.
Keywords: self-compacting concrete, mobility, strength, viscosity modifier, super plasticizer.
