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.

Before concrete repair, the cleaned steel rebar of reinforced concrete structures is coated with REKS® PRAYMER, a one-component primer with rebar corrosion inhibitors. It is needed if the rebar lies right at the concrete surface or chlorides are present in the concrete, and also when the repair mortar cannot be applied immediately after cleaning the steel. The mixed material is used within 60 minutes, the wet density is 1.95 t/m³; packed in 5 and 10 kg pails and 20 kg bags, the material is approved for use at domestic and drinking water supply facilities.
