MAPEGROUT SV

Ultra high performance, rapid-setting and hardening, compensated-shrinkage, hi-flow cementitious mortar applicable at temperatures down to -5°C for repairing concrete and fixing urban features in place

WHERE TO USE

•Repairing concrete structures that require the use of free-flowing mortar, including at low temperatures.

•Repairing industrial floors, roads and runways that need to be put back into service quickly.

•Fixing manholes and manhole covers quickly in place.

TECHNICAL CHARACTERISTICS

Mapegrout SV is a one-component, ready-mixed powdered mortar made from special hydraulic binders, highstrength cement, synthetic polyacrylonitrile fibres, selected aggregates and special additives according to a formula developed in MAPEI research laboratories. Thanks to its special composition, this product develops very high mechanical properties after short curing periods, even if applied at temperatures down to -5°C.

When Mapegrout SV is mixed with water it has a fluid consistency, which makes it suitable for casting into sealed formwork in layers up to 5 cm thick without segregation risk.

For thicknesses over 5 cm, Mapegrout SV must be added up to 35% of Gravel 6-10 on the weight of the mixture (for example: for 100 kg of mixture 65 kg of Mapegrout SV + 35 kg of Gravel 6-10).

Thanks to its rapid hardening properties, the mortar sets to foot traffic and may be used by wheeled vehicles just a few hours after application at +20°C.

Mapegrout SV complies with the principles defined in EN 1504-9 (“Products and systems for the protection and repair of concrete structures: definitions, requirements, quality control and evaluation of conformity. General principles for use of products and systems”), and the minimum requirements of EN 1504-3 (“Structural and non-structural repairs”) for R4-class structural mortars.

CONSUMPTION

•Used neat: 20 kg/m² per cm of thickness.

•Used ad micro-concrete with Gravel 6-10 at 50%: made up of 65 parts of Mapegrout SV and 35 parts of gravel (s.s.d. condition): approx. 13.8 kg/m² per cm of thickness (approx. 7.4 kg/m² of Gravel 6-10).
