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.

In REKS® Fiks Epo T/VN the (A+B):C ratio sets the consistency: 1:2 — flowable, 1:3 — plastic, 1:4 — thixotropic. The three-component compound based on modified epoxy resin and amine hardener is used for supports under bearing plates, precise setting of base plates, bridge bearings, screeds in premises with very high loads and fixing rails in sleeperless track. After 7 days compressive strength is at least 60, 55 and 50 MPa respectively, freeze-thaw resistance F1 200; the red version has a shorter gel time than the grey one.
