Gidrobeton SRG-F1 — fibre-reinforced shrinkage-compensated repair mortar

Thixotropic repair mortars

Polypropylene fibre and compensated shrinkage are the main features of Gidrobeton SRG-F1, made with Portland cement and aggregate up to 5 mm. It is used to repair defects in concrete and reinforced concrete structures in interior and exterior work, including in tanks and treatment plants. At 28 days the compressive strength is at least 50 MPa, flexural 4.5 MPa, bond to concrete 2.0 MPa, frost resistance at least 300 cycles.
