Pakol Litevoy 600K FAST — flowable mix with ultra-rapid strength gain
Flowable mix for fast-track structural repair of floors, roads and bridges; 20.0 MPa compressive after 2 h, workability retained for 20–30 min.

This thixotropic mortar with steel and polypropylene fibre is intended for structural repair and strengthening of vertical, inclined and overhead concrete and reinforced concrete surfaces subject to dynamic and vibration loads. It is used on bridges and overpasses, in tunnels and metro, on dams, tanks, columns and beams; steel fibre is supplied in separate 0.5 kg packs. After 28 days the flexural strength is 11.0 MPa (Btb8.0), compressive 65.0 MPa (B50), W20, F1 1000.
