High Abrasion Resistant Concrete Repair Mortar (formerly  Sika® Abraroc® SR)
Sika MonoTop®-3400 Abraroc is a 1-part, cementitious hand or machine applied structural concrete repair mortar with very high resistance to hydraulic abrasion.

• Ready to mix with water
• High abrasion resistance (A6 classification)
• High hydraulic abrasion resistance (equivalent to granite)

Usage:

• For new and refurbishment of structures subject to hydraulic abrasion (sewer pipes, sewage treatment plants, dams and maritime structures)
• Water retaining structures containing water (pH > 4)
• Abrasion resistant protective mortar layer
• Structures subjected to heavy abrasion or mechanical loads (Storage or loading bays, Silo floors, Industrial floors etc.
• Suitable for the environments XC1-XC4, XD1-XD3, XS1-XS3, XF1- XF4, XA1-XA3 according to the standard EN 206.
• Restoration work (Principle 3, method 3.1 and 3.3 of EN 1504-9). Repair of spalling and damaged concrete in infrastructure and superstructure works.
• Structural strengthening (Principle 4, method 4.4 pf EN 1504-9). Increasing the bearing capacity of the concrete structure by adding mortar.
• Preserving or restoring passivity (Principle 7, method 7,1 and 7,2 of EN 1504-9) – Increasing cover with additional mortar and replacing contaminated or carbonated concrete

Advantages:

• Ready to mix with water
• High abrasion resistance (A6 classification)
• High hydraulic abrasion resistance (equivalent to granite)
• Resistant to sea water and aggressive water conditions
• Applied up to 50 mm thick in one layer on vertical and horizontal applications
• Applied manually or mechanically (dry spray)
