Superplastyfikator BG97 40 is an aqueous solution of sodium salt of formaldehyde naphthalene sulfonic acid (NSF) polycondensates. The brown coloured product contains 40% of dry substance and is characterized by a very low content of free sulphates and chlorides, which allows its use as an admixture to concrete. It shows very good miscibility with other lignosulphonates plasticizers or melamine-formaldehyde condensates.

Properties and applications
  • allows to reduce the amount of batched water (even by 25%) without deteriorating the consistency of the concrete mix;
  • allows for less cement consumption, which reduces costs (while maintaining a constant water / cement ratio);
  • increases the compression strength of concrete (up to 30%);
  • extends the setting time of concrete, maintaining consistency;
  • not sensitive to overdosing, easy and convenient to use;
  • low dosage of 0.5 to 3% per mass of cement;
  • can be used at temperatures of up to -5 ° C without inhibiting cement hydration;
  • does not cause corrosion of reinforcing steel (low chloride content);
  • practically does not introduce air into the concrete mix;
