(Formerly known as Vetomortar CHR)
High strength structural repair mortar
Vetorep CR520 is a single component polymer modified fibered cementitious structural repair mortar that is ready to use and only requires the addition of water on site. Once mixed the products becomes a thixotropic mortar that is hand applied for the repair of demanding structural repair while being compatible with host concrete. Vetorep CR520 is composed of a blend of hydraulic cements, carefully selected and graded aggregates, fibers and special additives to give it its unique properties.
- Easy to use single component product
- High physical and mechanical properties
- Extremely low permeability providing reinforcement protection against corrosion as well as resistance to ingress of contaminants
- Non-Shrink properties ensuring repair dimensional stability
- Suitable for internal and external applications
- Breathable, compatible to host concrete
- Thixotropic properties allowing high build up in vertical and overhead repairs
- ASTM C157/157M-08e1
- EN 13062:2003
- EN 1504:2013

Design Criteria
Application area shall not exceed 2.5 m2 using Vetorep CR520, if such conditions exits use Vetorep CR521. Theuse of Vetorep CR520 in a single layer shall conform to:
Vertical application up to 75 mm.
Overhead concrete repair up to 50 mm.
Substrate
All damaged and weak concrete should be cut back to reach sound concrete and/or to a minimum depth of at least 10 mm. Corroded steel reinforcement should be grit blasted to remove all rust traces. In case of signifi cant loss in the steel reinforcement cross section, the steel should be replaced. Remove all concrete form around exposed steel reinforcements by 25 mm thickness. The perimeters of the repair area should be saw cut to a minimum depth of 10 mm. The prepared area should be cleaned thoroughly by brush and/or compressed air.
Priming
To accept Vetorep CR520, all grit blasted steel reinforcements should be primed within 2 to 4 hours with one or two coats of corrosion inhabitor for steel reinforcement Vetoprime CP437.
Areas to be repaired with Vetorep CR520 should be soaked with clean water before applying the repair mortar. All excess water should be removed prior to applying one coat of acrylic bonding agent Vetobond AB432.
Vetobond AB432 should be allowed to become tacky before applying the repair mortar
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fi tted with suitable paddle should be used. 2.8 to 3 liters of clean water should be added to a clean container.
The powder is then added slowly to the water while mixing continuously with low speed mixer/drill (400 - 600 rpm). Mixing time should be continued for 5 minutes until uniform consistency is obtained.
Vetorep CR520 Contains reins which may cause sensitization by skin contact. Avoid contact with skin and eyes and inhalation of vapor. Wear suitable protective clothing, gloves and eye/face protection. Barrier creams provide additional skin protection. Should accidental skin contact occur, remove immediately with a resin removing cream, followed by soap and water. Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed seek medical attention immediately. Do not induce vomiting.
Vetorep CR520 is non-flammable.
