The flowable non-shrink rapid-hardening fibre-reinforced mortar REKS® StruktoFluid is designed for repairing pavements of roads, airfields and open car parks, marine and river transport structures, reinforced and prestressed beams, floor slabs and bridge deck slabs. It is also used to install machine bases, fix beams and columns, strengthen foundations, inject into cavities and ducts, and fix bolts, anchors and embedded parts. Modulus of elasticity 37,000 MPa, compressive strength at 28 days from 65 MPa, flowability retained for 30–45 minutes, class R4 per GOST R 56378.
