REPAR TIX SFR

Structural thixotropic, shrinkage-compensated, reinforced fibre mortar

Code: REP.0135

Components: 1

Appearance: Powder

Thixotropic, rheoplastic, structural, shrinkage-compensated cement mortar, fibre reinforced with a mix of inorganic fibres in amorphous metal alloy (flexible and stainless) and alkali-resistant synthetic fibres, for the thickness restoration of works and infrastructural structures in severe marine, mountain and industrial atmospheres.

Characteristics

REPAR TIX SFR consists of special cements, silica fume, anti-shrinkage agents, specific additives and selected aggregates, high-performance in terms of adhesion, adherence, mechanical resistance, intrinsic watertightness, dimensional stability and overall hardness. REPAR TIX SFR is added with a mix of amorphous metal fibres of 30 mm (≥0.9% by weight) and multifilament synthetic fibres of 6 mm (≥0.08% by weight).

Use fields

Restorations, repairs of considerable thickness and size, structural recovery, reconstruction of concrete layer protecting the steel rods reinforcement, construction of reliable and durable coatings of road infrastructures (bridges, viaducts, tunnels, etc.) civil, hydraulic, industrial building works.

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".

Use method

Pour about 2/3 of the mixing water into the mixer, add REPAR TIX SFR and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 20-22% of the weight of the bag. After mixing is completed wait a few minutes before applying.

Place on site by rendering or using plastering /or shotcrete machines, use product quantities appropriate for the specific requirements of the construction site .

Application methods

- Finishing trowel

- Shotcrete machine

- Plastering machine

- Spatula

- Brick trowel

Tool cleaning

- Water

Permitted supports

- Plasters

- Concrete

- Cement-based or lime-based mortars

- Prefabricated concrete

- Mixed walls (bricks and stones)

Warnings, precautions and Ecology

Adopt the necessary care and moist hardening procedures of exposed surfaces that must be protected from rain, from direct sunlight, ventilation, etc.
