Repar Tix SFR
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).
Fields of application
Restorations, repairs and consolidations, even of considerable thicknesses and dimensions, on reinforced concrete and masonry structures. Reinstatement and reconstruction of the concrete cover on heavily deteriorated reinforced concrete works, even in particularly demanding and heavily stressed environments (marine, industrial, purification plants, hydraulic pipes). Reliable and durable structural consolidation of road structures (bridges, viaducts, tunnels, etc.). Reinforcement hoods on vaulted wall structures. Reinforcements and seismic adjustments in combination with structural glass fiber meshes from the ARMAGLASS line, Armaglass Connector glass fiber connectors, helical bars in Helix Steel AISI 304 stainless steel.
Allowed supports
Plasters
Concrete
Cement-based or lime-based mortars
Prefabricated concrete
Mixed walls (bricks and stones)
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).
Mode of use
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 .
