Retardant additive in concrete Teknoretarder
Supplement slow the hardening of concrete.
Teknoretarder is additive for concrete to slow its hardening.
Scope
- used in all types of concrete where necessary medium and long-term delay solidification
- to preserve the quality and strength characteristics of concrete during casting at high temperatures
- 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:
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.
