Repair and Reinforcement Systems / Cement Based, Flowable and Fast Setting Grout Mortar
GRT 25 is a cement based, single component, fast setting repairing and filling mortar with early mechanical strength.
Fields of Application
- Required high strength and fast curing areas.
- Installation of manhole frames.
- Repairing track and runway concrete pavements.
- Repairing vehicle and pedestrian traffic areas.
- Fixing of the kerbstone and paver.
Features and Benefits
- Fast setting and can be opened to traffic within 1 hour after curing.
- Early mechanical strength.
- High compressive strength.
- Does not peel off and bleed.
- Has flowable property.
- Easy to apply, mixed with only water.
Preparation of Substrate
Application surface must be dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. If there is a water leakage it must be drained or properly plugged. Concrete surfaces must be saturated with water before application.
25 kg bag GRT 25 is poured slowly into 3 - 3,5 liters of clean water under low speed mixer for 3-4 minutes until obtaining homogenous mixture. Mixing water must be clean and free of salt and lime. Mixture should be applied on the surface immediately because of quick setting property. GRT 25 is only applied for filling applications as 10-50 mm thickness for each layer. If needed much more thickness extra aggregate should be added on the grout in ratio of 1/2 (1 cup aggregate / 2 cups powder). Vehicle traffic or machinery should be avoided until full cure occurs.
For 10 mm thickness approximately 21 kg/m² is required.
