BIRSS 59 S2 M600 — thixotropic R4 mix with microfibre for bridges and tunnels

Thixotropic repair mortars

Polymer microfibre reinforces BIRSS 59 S2 M600, a thixotropic rapid-hardening mix for structural repair of vertical and horizontal concrete and reinforced concrete structures. It is used on bridges and in tunnels under dynamic and vibration loads, in reinforced and prestressed structures, port and hydraulic structures, and for filling joints and potholes without formwork. Compressive strength 20 MPa after one day and 60 MPa at 28 days, water impermeability W18, F2 400, frost resistance of the contact zone Fkz100.
