REKS® Fluid — rapid-hardening flowable R4 grout for work down to −10 °C

Cementitious grouts

High-precision grouting under bearings of columns and bridge spans, monolithic grouting of joints in precast reinforced concrete and repair of foundations of turbines, generators, engines and rolling mills are the main tasks of REKS® Fluid. The non-shrink rapid-hardening fibre-reinforced flowable mortar can be used at temperatures down to −10 °C and is also suitable for pavements of roads, car parks, airfields and hydraulic structures. After 2 hours it reaches at least 30 MPa in compression, after one day 50 MPa and at 28 days 80 MPa; class R4 per GOST R 56378.
