Pakol Torkret S (sulphate-resistant) — R3 shotcrete mix with watertightness W20
Sulphate-resistant fibre-reinforced mix for shotcreting bridges, tunnels, tanks and treatment plants; watertightness W20.

Floors, roads, airfields, bridges and equipment foundations subject to dynamic and vibration loads are repaired with this flowable mix containing steel and polypropylene fibre. The coarse-grained non-shrink mix with rapid strength gain is intended for structural repair of spalls, gouges and delaminations on horizontal and slightly inclined surfaces. Steel fibre comes in separate 0.5 kg packs; after 28 days the mix shows 11.0 MPa in flexure (Btb8.0) and 65.0 MPa in compression (B50), class R4.
