- While preparing cement suspensions, natural bentonite KAR-BEN must be mixed to water first and at least after two hours cement should be added.
- It is recommended to add 0,3% – 0,7% (Of solid material added) Sodium phosphate or 5 % sodium silicate to the cement suspensions, considering the application aim, depending the heat of the used water.
- It is more effective and economic to get enough natural bentonite KAR-BEN suspension ready at the beginning of the work.
