A reduced modulus of elasticity — at least 250 MPa after one day and 500 MPa after 7 days — distinguishes the black two-component acrylic polymer concrete REKS® AKRILIK ELAST VN. It is used to fill expansion joints and create transition zones when constructing them, to repair edges of reinforced concrete pavement slabs and loosened sleepers, and to reduce impact loads from vehicle wheels on roads, airfields and bridges. The compound is intended for horizontal surfaces in interior and exterior work; compressive strength after 7 days is at least 15 MPa.
