The influence of viscosity modifier brand BASF on rheological properties of self-compacting mixtures and the kinetics of curing of concrete. When determining the spreadability of the mixture with the locking ring installed, that the use of the modifier with water-retention effect increases the fluidity of the mixture, despite the presence of obstacles. During the complex introduction of superplasticizer and viscosity modifier was an increase in water demand of the mix, resulting in a loss of concrete strength. The possibility of obtaining smart dynamic concrete and the effectiveness of the use of the viscosity modifier in combination with various additives should be set on the utilization of cement in concrete.To ensure the competitiveness of the smart dynamic concrete viscosity modifier it is necessary to design the composition with the lowest specific consumption of cement due to the rational grain composition of the filler and the optimum dosage of chemical additives.
