Influence of Superplasticizer S-3 on the Technological Properties of Concrete Mixtures
In the process designing of concrete arise the problem - compatibility polycarboxylates with cement different parties. In some cases, when you receive the next batch of cement concrete mobility decreased sharply. Additive had to pick again. When choosing supplements examined its effect on the technological properties of concrete mixtures: workability, resistance to water gain, air entrainment. Test results showed that the addition of superplasticizer based on sulfonated naphthalene-formaldehyde resins (SNF) on the effectiveness of the plasticizing action is not inferior hyperplasticizer based polycarboxylate. Unlike polycarboxylates SNF additive has good compatibility with various cements, which provides stability regardless of the characteristics of the concrete mix to the vibrations of the chemical composition of cement. With increasing content of cement in the concrete superplasticizer efficiency increases, both in terms of workability, and in respect water gain of a concrete mixture.
