BIRSS 30 Spets — cement-polymer mix for vertical and overhead surfaces
Vertical, inclined and overhead concrete surfaces are repaired with BIRSS 30 Spets, a non-shrink fine-grained cement-polymer mix based on Portland cement, graded sand and mineral fillers. It is used to level defects, remove spalls, potholes and cavities, and restore elements damaged by corrosion of concrete or reinforcement when non-structural repair is subject to increased strength requirements. After one day 7.5 MPa in compression, at 28 days 30 MPa, W 12, F2 300; service from −50 to +200 °C.
