High Abrasion Resistant, High Strength Concrete Repair Mortar Sika MonoTop-3400 Abraroc is a one-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).
- 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 technique).
|
Usage - For new, and the refurbishment of, structures subject to hydraulic abrasion (sewer pipes, sewage treatment plants, dams, spillways, slipways, marine jetties and other 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 of 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.
