Betonfix HCR EVO TX
High performance, high ductility thixotropic cementitious grout with fibres
Betonfix HCR EVO/TX is a two-component system used for non-shrink cementitious grouts, with corrosion inhibitors, fiber-reinforced, with thixotropic consistency, very high mechanical strength at short and long curing, high ductility, high resistance to sulphates.
Applications
Betonfix HCR EVO/TX system is used to carry out the restoration and consolidation, in small thicknesses, of inclined structural elements, such as sloping slabs (structural reinforcement with low thickness collaborative extradossal casting for slabs) and for the restoration and reinforcement of concrete beams and pillars.
Certifications
The Betonfix HCR EVO/TX system is CE marked as R4 mortar according to EN 1504-3 ("Structural and non-structural repair")
Application
The system is ready to use with the simple addition of potable water. The mixing of the products can be carried out in a simple concrete mixer or preferably with a mechanical mixing unit. Add half of part A (powder) and start mixing adding half the amount of water shown in the table. Mix until a homogeneous and fluid mixture is obtained, then add the remaining part of the powder and the remaining part of water until the desired mixing ratio is obtained. Mix further for at least another 5 minutes. Weigh the quantity of fibers required in relation to the volume of the casting to be performed and add them gradually (over a period of about 3 minutes), using special fiber routing equipment. Add all the fibers, mix for at least 2-3 minutes. The substrate must be previously treated by mechanical scarification suitable to guarantee a rough surface, and free of flaking parts, clean and free from dust, grease, oil and release agents in general. Application on slabs Check if exposed rods treatment is necessary. Assess the need for insertion of shear connectors to ensure a connection of the system with the existing slab and steel connectors for the connection to the perimetral structures. The presence of the connecting pins is mandatory for low thicknesses castings. Saturate the area to be treated, taking care to eliminate, at the time of casting, any pools of water. Prepare the guides (wood or metal), as high as the thickness that has been planned for the reinforcement, to help the operator in the screeding phases of the material. Run the casting Betonfix HCR EVO/TX and, before proceeding with the straight edge, on fresh product with a spiked roller, of suitable thickness, in order to eliminate any air pockets. Apply Antievaporante W on fresh in order to allow the perfect curing time of casting. For special application contact the Technical Department.
