Description :

Ultra high-performance high ductility free-flowing micro-concrete reinforced with metal fibres.

Technical Charateristics :

Planitop HPC Floor 46 is a ready-mixed powdered micro-concrete made from high-strength cement, selected
aggregates, special admixtures and stiff steel fibres according to a formula developed in the MAPEI Research &
Development laboratories.
When Planitop HPC Floor 46 is mixed with water it forms a fluid micro-concrete suitable for casting into formwork
without segregating in layers from 2 to 8 cm thick, and without the need for electro-welded reinforcing mesh.
To allow the product’s expansive properties to develop fully and correctly, Planitop HPC Floor 46 must be mixed with
water and cured in a damp environment. To allow expansion in the open air, Planitop HPC Floor 46 may also be admixed
with 0.25% of Mapecure SRA, a special admixture which has the capacity to reduce plastic and hydraulic shrinkage.
Mapecure SRA carries out an extremely important role and guarantees better curing of the micro-concrete. When mixed
with Planitop HPC Floor 46 it may be considered a technologically advanced system, in that the admixture has the
capacity to stop the water evaporating too quickly from the micro-concrete and encourages the development of
hydration reactions.
Mapecure SRA acts basically as an internal curing agent and, thanks to its interaction with some of the main components
in the cement, it reduces final shrinkage by 20% to 50% compared with the same product without the admixture, which
means there is also a lower risk of cracking.
The use of Mapecure SRA may reduce mechanical performance characteristics slightly by 5-6%.
The product may also be used without adding Mapecure SRA when climatic conditions allow a favourable curing cycle to
be carried out.
Once hardened, Planitop HPC Floor 46 has the following characteristics:
very high flexural and compressive strength;
high ductility;
high resistance to cyclical loads;
impermeable to water;
excellent adhesion to old concrete, if dampened with water before application, and to rebar, especially if treated
beforehand with Mapefer or Mapefer 1K;
high resistance to wear from abrasion or impact loads.
Planitop HPC Floor 46 complies with the principles defined in EN 1504-9 (“Products and systems for protecting and
repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles
for the use and application of systems”), and the minimum requirements of EN 1504-3 (“structural and non-structural
repairs”) for R4-class structural mortars.
Planitop HPC Floor 46 is covered by the Certificate of Technical Assessment (CVT) n° 264/2020 released by 2^ Div. II of STC
– CSLP.
