Teknoretarder is additive for concrete to slow its hardening.

Scope

  1. used in all types of concrete where necessary medium and long-term delay solidification
  2. to preserve the quality and strength characteristics of concrete during casting at high temperatures
  3. when pouring a large volume of concrete


The features and benefits

  • reduces the amount of heat produced during hydration
  • reduces thermal shrinkage
  • allows you to pour concrete at temperatures above 35 C
  • facilitates the process of casting and does not affect the final strength of concrete


Notes on application / Limitations

Teknoretarder can be added to the concrete at the construction site or at the factory when mixing. Mixing is carried out not less than 5 minutes. To improve the setting process of the concrete it is necessary to use additional measures: depending on the ambient temperature it is necessary to use a modified cements and special additives. The ratio of water to wagamama should be reduced by 3-5%.

After application the surface should be protected from direct sunlight, strong wind, high air temperature (above 35° C), rain and frost. During operation, observe the safety and labour protection.
