Mapegrout Betontech HPC and HPC10, innovative renovation micro-concrete with a work-hardening effect developed by Mapei, are used for restoring and repairing concrete. They are mainly used for repairing kerbs along the sides of motorways and for rebuilding and strengthening structural elements, such as beams and pillars.
Made from high-strength cement, selected aggregates, special additives and structural fibres, Mapegrout Betontech HPC and HPC10 are fibre-reinforced mortars with the capacity to improve post-cracking behaviour of repaired concrete elements. With these types of mortar it is possible to obtain a ductile failure mechanism, that is, the mortar is able to maintain its mechanical characteristics as the cracking process advances. For this reason, this type of product is particularly recommended for repairing structures subjected to dynamic loads.
The maximum particle size of the aggregates in Mapegrout Betontech HPC is 6 mm, which enables layers between 3 cm and 10 cm to be applied. The maximum particle size of the aggregates in Mapegrout Betontech HPC10, on the other hand, is 10 mm, which enables layers between 5 cm and 30 cm to be applied.
The two products comply with the principles defined in EN 1504-3 and the minimum requirements specified by EN 1504-3 for class R4 structural mortars.
