BIRSS RSM-2M M350 — rapid-hardening fibre-reinforced repair mix
Structural repair of concrete and reinforced concrete is the main task of BIRSS RSM-2M M350, a rapid-hardening thixotropic mix with reinforcing fibre and sand up to 1.25 mm. It is used to restore elements of road bridges and tunnels and structures under dynamic loads, and to fill joints between precast elements, potholes and cavities without formwork. After one day the mortar reaches at least 15 MPa in compression, at 28 days 35 MPa; water impermeability W12, frost resistance F2 400, produced to STO 05668056-004-2012.
