ARGOTEC REPARACIÓN R4 is a thixotropic polymer modified mortar (PCC), single-component, high-strength and non-shrink, for structural repair of concrete elements, formulated with a mixture of hydraulic binders, selected aggregates, polymers, corrosion inhibitors and fibres that provide excellent adhesion and mechanical properties.
The repair of concrete elements will be carried out with ARGOTEC REPARACIÓN R4 mortar, from the Argos cement derivatives company, class R2 according to the UNE EN 1504-3 standard, in accordance with principle 3 (methods 3.1 and 3.3), principle 4 (method 4.4.) or principle 7 (methods 7.1. and 7.2.). The fixing substrate shall be sound, clean, free of friable parts, fully hardened and have completed its time of dimensional variation. The construction joints shall be respected.
- Conservation and restoration of coats. Principle 7. Methods 7.1 and 7.2.
- Repair of prefabricated elements.
- Repair and regeneration of structural elements.
- Structural concrete reinforcement works. Principle 4. Method 4.4.
- Concrete repair work. Principle 3. Methods 3.1 and 3.3.
- Repair work on edges, cornices, balcony edges and roofs.
