CERTIFICATIONS
Betonfix CR is CE marked as R4 mortar according to the requirements of EN 1504-3 (structural and non-structural repair).
STORAGE
Protect from humidity. Store the product in a dry, sheltered place. Stored in these conditions and in unopened containers, the product remains stable for 12 months.
USES
- Betonfix CR is used to create collaborative concrete castings, to fill rigid structural joints with thicknesses of over 5 cm, for repair in high thicknesses of deteriorated reinforced concrete structures, floorings, ceilings, slabs and road and railway beds.
- For thicknesses greater than 10 cm, mix Betonfix CR with about 30% of siliceous inert washed and free of impurities, with particle size not lower than 6 mm and with a maximum diameter according to the thickness of casting.
ADVANTAGES
-Final mechanical development required for R4 mortars within the first 7 days. With corrosion inhibitors, no metallic particles or chlorides. No cracking risk. -Mixed with additives or lactic acid is used for applications with specific requirements. Available in variants with different kinds of fibers.
-Durability and resistance to environmental stress evidenced by works from the beginning of the 80s. -High protection of reinforcement rods: guaranteed by the carbonation resistance and by the low permeability to chloride ions. -Excellent workability and easy application (manual or mechanized).
APPLICATIONS
-Betonfix CR is used to create collaborative concrete castings, to fill rigid structural joints with thicknesses of over 5 cm, for repair in high tchicknesses of deteriorated reinforced concrete structures, floorings, ceilings, slabs and road and railway beds. -The product is ready-to-use on the addition of drinking water, according to the quantity shown in the table The substrate to be treated must be perfectly clean, free from grease, oil and separating agents in general. Roughen the concrete surface with a bush-hammer.
-The superficial tensile strength of concrete “Pull off” must not be lower than 1,5 Mpa, as indicated in the procedures for the quality control of substrate according to EN 1504- 10. If substrate has lower mechanical features, contact our Technical Department. Where metal reinforcements are visible, remove concrete and protect them with Betonfix KIMIFER, applied by brush.
-Soak the area to be treated eliminating any pools of water when casting. Mix Betonfix CR for about 5 minutes with a cement-mixer adding 3/4 of the water required and then pour the product and the remaining water until you get the consistency required. The patch layers must have a proper reinforcement under pressure anchored to the existing structure with an embedded steel bar min 2 cm thick.
-For thicknesses greater than 10 cm, mix Betonfix CR with about 30% of siliceous inert washed and free of impurities, with particle size not lower than 6 mm and with a maximum diameter according to the thickness of casting. For particular applications, our Technical Department will provide further information.
