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.

Machine bases, fixing of beams and columns, fixing of bolts, anchors and embedded parts, and injection into cavities and ducts are the works REKS® Graut M is intended for. It is a non-shrink highly flowable cementitious mortar of class R4 per GOST R 56378; flowability is retained for at least 30 minutes. Compressive strength is from 30 MPa after one day and 60 MPa at 28 days, bond to the substrate at least 2.1 MPa, freeze-thaw resistance F2 400, water impermeability W16.
