Superplasticized technological properties of concrete mixtures

Studies have shown the ability of the Additive-3 (C-3) in a significant dilution of the concrete mix. The mixture with OK=4 cm thinned to mobility OK more than 20 cm, and in experiments on the blurring of the test (for Suttardu) superplasticizer C-3 showed higher efficiency than superplastifikatory used. Furthermore, the addition of Additive-3 (C-3), unlike the polycarboxylates not possesses selective activity against various cements, which ensures the stability characteristics of the cement concrete mix different batches supplied during construction. With increasing content of cement in the concrete superplasticizer efficiency increases C-3, both in respect of workability and in relation to the concrete mix water separation.
