Sulphate-resistant thixotropic mortar, reinforced with fibres and highly resistant, for structural repair of concrete.

PROPAM® REPAR TECHNO 40 is a non-shrinkage, single component, thixotropic repair mortar with good adherence and very high mechanical strength, and it is reinforced with fibres and specially formulated for structurally repairing concrete in aggressive environments.
It complies with the requirements of standard EN 1504-3 class R4, EN 1504-2 and EN 1504-7. It has CE Marking 2+, for uses in building and civil engineering works of all kinds.

Fields of application
- Columns, beams, joists, wrought iron edges and slabs, made with anti-sulphate cements.
- Chimneys, cooling towers or bays, etc.
- Decanters, digesters, purifying plants, etc.
- Tunnels and buried structures in aggressive environments.
- Structures in saline environments or in contact with sea water.
- Rehabilitating building structures.
It allows implementing the structural repair with just one product and in one step. Sulphate resistant. High thixotropy, applicable in thicknesses of 2 to 50 mm, manually or by projection. High mechanical strength. No shrinkage and reinforced with fibres, it does not crack. Its accurate granulometry provides a cosmetic finish similar to that of the original concrete. Free of chlorides, its high pH protects against the corrosion of metal elements, such as rebars, anchorings, etc. Excellent adhesion strength to concrete, even on substrates that are not very porous. Impermeable. Applicable indoors and outdoors. High resistance to carbonation and the freezing-thawing cycles. Can be applied by projection. It withstands temperatures between -50 ºC and +500 ºC. Excellent workability. Protects the armor from corrosion by inhibiting its oxidation.
