Fast hardening, thixotropic cement mortar

Code: REP.0137

Components: 1

Appearance: Powder

Structural, rheoplastic, thixotropic cement mix with controlled shrinkage, with adequate super-pozzolanic filler additives, hold accelerators and glass micro-fibres. The mix is equipped with very fast hold, excellent workability and excellent adhesion on cement supports to re-build. The product was mainly designed for small/medium repairs and reconstructions in environments where the fastness of application is important, such as works on roads, ports and airports.

Use fields

Suitable for surface regulation and reconstruction works on missing sections and cavities, especially in works involving structural renovation of worn concrete. Volumetric reconstruction of concrete cover on structures in reinforced concrete or prefabricated ashlars.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface". An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes).

Use method

Pour about 2/3 of the mixing water into the mixer, add REPAR TIX SPEEDY HP and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 16 - 18% of the weight of the bag.

Having finished mixing, immediately use the product for the works necessary, paying attention to its fast hardening. You are advised to use a little product at a time, only the quantity usable within 10 minutes after mixing (attention, the ambient temperature can also considerably affect the hold time of the product!).

Application methods

- Brick trowel

- Spatula

Tool cleaning

- Water

Permitted supports

- Asphalt

- Concrete

- Prefabricated concrete

Warnings, precautions and Ecology

Do not apply in case of direct exposure to sunlight and/or excessive ventilation. Cure the protection and the prolonged moist hardening of exposed surfaces. Given the short setting time, it is recommended to prepare small amounts of product at a time, to avoid waste and scraps.
