DESCRIPTION OF KF-D
Light gray powder with specific smell. After application, the smell disappears.
This inorganic compound works as an admixture to cement containing Earth-Materials-Sealants (EMS).
BENEFITS
- Initial solubility of KF-D with water is 100%.
- Final hardened product is insoluble even in acid or salt water.
- Completely reduces bubbling of standard mixture.
- Hardening time is adjustable.
- KF-D does not affect the environment.
- The application of KF-D using injection or sorption treatment creates a chemically altered structure with increased density and reduced hydraulic conductivity.
USES OF KF-D
- Improves density and impermeability of soil or severely deteriorated structures. KF-D added to standard EMS mixes can be used for injections under or into sinkholes, foundations, tunnels, dams, wet and polluted soils, etc.
- Strengthens the standard EMS formula and increases waterproofing.
- Improves binding with standard concrete fillers and particles of soil.
APPLICATION
Add 5.5 Lbs of KF-D per 200 Lbs of cement or 2.5 Kg of KF-D per 100 Kg of cement to EMS and mix for 10 minutes.
Add pure water to produce a water to cement ratio of 0.38.
Mix for 5 minutes and unload into the hopper of pump station.
Apply mix through injectors into the targeted damaged areas.
The KF-D and EMS premix can be poured onto soils with or without subsequently mixing with the soil for stabilization and waterproofing of soaked areas.
