SIRIOBETON FA is a mixture produced with special hydraulic binders, selected aggregates, microsilica, polypropylene fibers, and additives that give it a high degree of workability and adhesion for vertical and overhead applications, with resistance to aggressive external agents. Compliant with UNI EN 1504-3.
Directions for use: completely and thoroughly remove all degraded concrete until a sound surface is obtained, free from loose parts and substances that could impair the adhesion of SIRIOBETON FA to the substrate.
For repairs with thicknesses greater than 2 cm, it is recommended to install an electro-welded mesh with spacers (at least 1 cm from the substrate) and to provide a concrete cover of at least 1.5–2 cm.
Moisten the contact surfaces until complete saturation. Any excess water on the surface or in surface cavities must be removed with compressed air or sponges immediately before application.
Mix for approximately 3–5 minutes (to obtain a homogeneous, lump-free mixture) in a concrete mixer already containing 2/3 of the water required for the mix.
Achieve the desired workability by completing the addition of water. The amount of mixing water may vary depending on environmental thermo-hygrometric conditions.
Application guidelines: the product is ideal for structural plasters, for reconstructing the geometry of degraded structures, for coating dam walls, channels, viaducts, bridges, and mountain weirs, for creating layers resistant to chloride and sulfate attack, for protecting structures subject to intense freeze–thaw cycles, for producing anti-wear coatings, and for waterproofing tanks.
Advantages: thanks to its high adhesive strength, it allows the application of significant thicknesses in a few passes, both with manual application and by means of plastering machines or shotcreting equipment, while ensuring very high abrasion resistance, increased durability against freeze–thaw cycles, an increase in electrical resistivity of more than 25 times, complete absence of bleeding, a significant reduction in waste (up to 15–20 times), and excellent resistance to chemical attack.
