INFLUENCE OF POLIARILSULFONSULFONATES ON THE CEMENT SYSTEMS
By the carried out researches is established, that the different impacts of the additives on cement systems is connected to distinction of molecular weights of the additives. With increase of molecular masses their effect raises. Besides in concrete mixes of identical plasticity with the additive SAS water separation 2 times is less than that with known superplasticizers
