REKS® Strukto R4 — rapid-setting fibre-reinforced repair mortar of class R4
Rapid-setting mortar for repairing concrete after rebar corrosion and impact, resistant to liquid acidic media; from 30 MPa compression after one day.

Deep anchor pockets for large anchor bolts under heavy process equipment are filled with the three-component cold-curing epoxy grout REKS® Epolit. The highly filled material also serves as a high-strength grout for fixing critical equipment with dynamic loads — generators, turbines, compressors, diesel and gas engines, and pumps. After 3 days compressive strength is at least 80 MPa, after 7 days 100 MPa, flexural strength from 25 MPa; the pot life after mixing components A and B at +20 °C is at least 90 minutes.
