摘要

The self-healing capacity of 25.4, 30.2, 34.9, 41.3, and 50.8 mm-diameter circular fully penetrating holes in geosynthetic clay liners under 2 kPa applied stress is compared after full hydration using deionized water and 10 mM CaCl_2 solution. In deionized water, holes with diameters up to 41.3 mm self-healed but with an indentation about 1~2 mm-deep at the center of the larger self-healed zones. The hole with a diameter of 50.8 mm self-healed but the hole was filled with a layer of bentonite slurry with a 4~6 mm-deep indentation. Submerged in 10 mM CaCl_2 solution, holes with diameters less than 34.9 mm self-healed with a 1~6 mm-deep indentation. The 41.3 mm-diameter hole did not close up, leaving a 26.5~28.5 mm-diameter hole. This study shows the importance of the hydrating fluid on the potential for self-healing.
