Controlled-shrinkage fibre-reinforced fluid mortar for concrete repair. Use Mapegrout Hi-Flow for the repair of very damaged concrete structures where the use of fluid mortars is recommended. Made of cement binders, selected graded aggregate special additives and synthetic fibres, Mapegrout Hi-Flow is prepared by mixing a 25 kg bag with 13-14 and 0.25% of Mapecure SRA. The product may be used without adding Mapecure SRA, when environmental conditions permit excellent curing. The mix must be poured into sealed formwork. Care must be taken to let air escape in order to prevent air-bubbles. Thicknesses up to 4 cm can be repaired with Mapegrout Hi-Flow. For greater thicknesses, the addition of appropriately graded aggregate is recommended. Mapegrout High-Flow meets the minimum requirements of EN 1504-3 standards for R4-class structural mortar.
