Product description
Self-leveling, expansive, ready-to-use cement mortar for grouting, anchoring, concrete repair. Granularity 0/4 mm. It is characterized by an accelerated increase in strength and a slight expansion in the liquid-plastic phase.
Features
- self-spilling
- frost-resistant
- resistant to vibrations and impacts after setting
- non-corrosive to steel, non-toxic, non-flammable
- it expands by gas evolution while still in the liquid-plastic phase
- the ability to regulate the consistency
- easy to use and mix - only water added
- fast strength development, high final strength
- in accordance with the rules of structural repairs for anchoring steel bars in reinforcing bars in accordance with PN-EN 1504-6
- meets the requirements for a repair mortar of class R4 in accordance with PN-EN 1504-3
- reaction to fire class A1
Application
- grouts for machines, poles
- embedding anchors, bars, railings and other steel structures in concrete
- pouring joints element in prefabricated elements. Filling defects and joints in concrete on horizontal surfaces
- suitable for repair work (principle 3, method 3.2 of PN-EN 1504-9); repair of peeled or damaged concrete in buildings, bridges and other reinforced concrete structures
- suitable for structural reinforcement (principle 4, method 4.2 of PN-EN 1504-9); increasing the load-bearing capacity of the concrete structure by mounting the bar in the reinforcement holes in the openings
- suitable for structural reinforcement (principle 4, method 4.4 of PN-EN 1504-9); increasing the load-bearing capacity of the concrete structure by adding a mortar layer
- suitable for maintaining or restoring passivity (principle 7, methods 7.1 and 7.2 of EN 1504-9); increased cover of the reinforcement and replacement of damaged or carbonated concrete
