REKS® AKRILIK ELAST VN — acrylic polymer concrete for expansion joints and slab edges
Rapid-hardening highly filled acrylic polymer concrete with a reduced modulus of elasticity for expansion joints, slab edges and sleepers.

REKS® Fayber L contains two types of fibre at once — polymer and flexible brass-coated metal fibre; this flowable non-shrink mortar is intended, among other things, for reinforced concrete under high bending loads. It is used to repair pavements of roads, car parks, airfields and bridges and to build and restore dynamically loaded and earthquake-resistant structures, including at temperatures down to −10 °C. Compressive strength is from 30 MPa after 2 hours, 50 MPa after one day and 80 MPa after 28 days, flexural strength at 28 days at least 16 MPa; kit 26.25 kg.
