Cement ultra-fast freezing that hardens in a few minutes. Develops early mechanical strength from the first few seconds of mixing it with water. O processing time is 1-2 minutes at 23°C, and the hardening is achieved in 3 minutes. Open to direct stress, it is weatherproof, frost-resistant and does not shrink. Does not contain chlorides or other corrosive components, while containing no inhibitor. May be mixed with sand – gravel and common Portland cement in different proportions, so as to affect and regulate the clotting time, giving high early strength, no shrinkage, and increased tightness of the hardened product. The minimization of coagulation time, depending on the technical requirement, as a result of the significant reduction in the probability of damage from frost. It is classified as repair of concrete, in the category of PCC R3 according to EN 1504-3.

The Durofast, with only the addition of water, are used for direct sealing hole with intense water leakage in tanks, manholes, ducts, gutters, and cement pipes.
