Description: a chemical agent based on sulfonaphtalic derivatives, as well as on dispersion of cement particles due to show of electrostatic and steric effects of adsorbed molecules of the plasticizer.
Application: applied in the process of well cementing as a plasticizer to the grouting mortar in order to adjust rheological properties of grouting mortars, reduce flow resistance of the cement mortar, reduce the pressure of injection and squeezing.
Recommended discharge: injected both to the grouting fluid and the cement. Recommended range of concentration of the additive is 0,1–0,6% by weight of dry cement.
