Abstract
Described herein is a composition for use in a geosynthetic clay liner, the composition comprising particles, at least some of which are discrete particles and each comprise: a compacted swelling clay, the clay having been compacted such that it at least partially surrounds a fluid-loss preventing polymer. Also described herein is a clay liner formed from the composition, a method for producing particles for use in a geosynthetic clay liner, and a method of forming a clay liner.
Claims18
A composition for use in a geosynthetic clay liner, the composition comprising particles, at least some of which are discrete particles and each comprise:
- a compacted swelling clay, the clay having been compacted such that it at least partially surrounds a fluid-loss preventing polymer;
- wherein the particles, if divided up into three samples, the first sample having a size distribution of particles of +1 mm, the second sample having a size distribution of particles of +0.5 mm/−1 mm, and the third sample having a size distribution of 0.5 mm, and each of the first, second and third samples would show a fluid loss result of less than 15 ml for NaCl @1%, when measured according to ASTM-D5891.
