Clay geosynthetic barriers -- Determination of water absorption of bentonite
This standard was last reviewed and confirmed* in 2016.
*Therefore this version remains current
ISO 10769:2011 specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR-C). Water absorption depends on the specific surface of the fine particles and the surface activity of the bentonite. The test provides an index value for production control testing of GBR-C.
