KarBen Natural Bentonite (Non-treated)
FEATURES

It is a clay mineral being up to standards of API 13 A ( Nontreated bentonite )

It has Sodium based content and contains at least 90 % montmorillonite. It is completely natural ,contains not even one type additive. It has high swelling capacity ( 15-20 times by volume)

It is in conformity with TS EN 13500 Nontreated Bentonite Specifications.

It easily disperses and doesn’t become lumpy when it is added to water.

GENERAL INFO
  • 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.
