(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.

note: Vetorep CR520 repair area should not exceed 2.5 m2 in single application.
Original sealed kits of Vetorep CR520 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded temperature controlled place <35ºC.
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.
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.
To accept Vetorep CP520, 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
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.
