Dry cement-mineral mix for gunite work on vertical and overhead concrete surfaces

Fields of application:
Using for gunite concrete on dry and wet methods in repair and construction works.

Concrete characteristics with TSEMINS TST(T):

High freeze-thaw durability;

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 works on dry methods mix is ready to use.

Rate of application: 1,9-2,3 t/m³

Curing of concrete:
После нанесения бетонного раствора его поверхность следует защищать от преждевременного пересыхания, так как при этом нарушаются условия необходимые для нормального вызревания прочности бетона.

After application of concrete solution its surface should be protected from premature extinction because of conditions that is necessary for normal maturing. Safety methods are identical to ordinary concrete. Time of concrete curing with TSEMINS is reduced 1,5-2 times at the expense of much faster hardening.
