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.
Abstract
Overview
EN ISO 10769:2011 - Clay geosynthetic barriers: Determination of water absorption of bentonite specifies a standardized laboratory method to measure the water absorption of the bentonite component used in clay geosynthetic barriers (GBR‑C). The method produces an index value for production control and quality assurance. Water absorption reflects the specific surface and surface activity of fine bentonite particles and is measured as the mass of water absorbed relative to the dry mass of the specimen.
Key topics and technical requirements
- Scope & principle: Measures the ratio of absorbed water to dry bentonite mass (water absorption, wA) using continuous mass recording over a 24‑hour test period.
