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.

The highly flowable expanding cementitious binder REKS® StruktoLit is used to prepare injection grouts, mortars and concrete. These are used to repair and build road and airfield pavements by the colmatation method, bridge structures and civil buildings, to fill cavities and cracks in porous concrete and masonry by pouring or injection, to consolidate foundations and to fill rigid joints with shrinkage-compensated concrete. The injection grout reaches at least 80 MPa in compression at 28 days and expands by at least 0.3 % in the plastic phase, mortar and concrete reach from 62 MPa.
