Fine-grained, quick-setting mortar for concrete replacement, repair and re-profiling. It is characterized by a very fast increase in strength. It can be mechanically loaded after 60 minutes. The consistency of the mortar can be adapted to both horizontal and vertical applications.

Properties

• very fast growth of early strength
• it can be mechanically loaded after 60 minutes
• can be used on horizontal or vertical surfaces
• very little contraction
• low stress on bonding
• With the help of additives in Koester Turbo, the properties of the mortar can be adapted to individual requirements

Application

• concrete repair on internal and external surfaces
• surfaces requiring high early strength values, such as renovation of industrial floors without interruption of operation, repair of roads and driveways, repair of architectural concrete, repair of bridges and other infrastructure
