Dry cement-mineral mix for concrete with high aggression resistance

Field of application:
Repair works with making high aggression resistance concretes.

Characteristics:

• It is mineral composition with fine-grained addition;
• Ready to use after water adding;
• Cold and influence of salt and weak acids resistant;
• High adhesion including metals.

Claims to work surface:
TSEMINS TST is used for repair work on concrete or reinforced concrete surfaces. These surfaces must be prepared with demounting ruptured surfaces manual or mechanized method. For high adhesion air or water blasting can be used. Surface must be wet before application repairing solution.

Methods of preparation:

• Concrete solution is prepared in concrete mixers (mortar mills) with recommended quantity of water. For example, on 100 kg of mix using 18 l of water.
