MAPECURE SRA

Curing admixture with the ability to reduce hydraulic shrinkage and the formation of microcracks

WHERE TO USE

The product is added during mixing to repair mortars from the Mapegrout range (Mapegrout T40, Mapegrout T60, Mapegrout Thixotropic, Mapegrout Hi-Flow, Mapegrout BM, Mapegrout FMR and Mapegrout Easy Flow), to binders, such as Stabilcem and Stabilcem SCC, and to all types of concrete, to allow them to expand during the first few days of curing, including during air curing. This property helps reduce the formation of micro-cracks and also guarantees that the final level of hydraulic shrinkage is extremely low.

Some typical application examples

Construction and repair of:

· floor joists and motorway viaduct piers;

· industrial floors;

· multi-storey car parks;

· hydraulic works, such as canals, overflow channels, tanks, etc.;

· prefabricated concrete elements such as cupolas, beams, pillars, buffer panels, etc.;

· lining road and railway tunnels.

HOW TO USE

Repair mortar:

· pour the amount of water recommended in the Technical Data Sheet for the product to be used into a concrete mixer;

· start up the concrete mixer and mix the contents for a few minutes;

· add Mapecure SRA at a rate of 0.25-0.5% by weight of the mix;

· continue mixing until a lump-free, homogenous mix is obtained.

Concrete:

· add Mapecure SRA to the mix at a rate of 5-8 l/m³ after adding the cement, aggregates and 70% of the mixing water required;

· then add the remaining water and mix until the required consistency is obtained.
