Poliarilsulfonate superplasticizers in the amount of 0.75-1.25 wt.% while maintaining the specified plasticity reduces the water demand of concrete cement mortar and concrete mix by 25-30%. Otherwise they allows to increase the precipitation of the cone from OK = 2 - 4 cm to 24 - 26 cm with the same W/C and also they allows to reduce the amount of water separation of the concrete mix in comparison with the known superplasticizers 2 times. It is shown that with an increase in the cement content in the mixture, the effect of poliarilsulfonate superplasticizer increases.
