Koester - Turbo Mittel high early strength repair mortar

Fast-setting mortar for concrete repair, re-profiling or replacement. Reinforced with Italian knives. It is characterized by high chemical and mechanical resistance. 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 increase of early strength (it can be mechanically loaded after 60 minutes)
• Depending on the amount of mixing water (consistency), it can be used on horizontal or vertical surfaces.
• high resistance to chemical and mechanical stress
• 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 road and driveway, embedding of coils in concrete, repair of bridges and other infrastructure facilities
