bentonite grinding test:

Results of the tests on bentonite (Part 1)

2012-3-27 · For the granite/bentonite interface two preliminary test were performed in a methacrylate cell (tests GB1 and GB2). A granite core of 5.2 cm in diameter and 6.6 cm in height was longitudinally cut in two halves, what resulted in rough granite surfaces. One of the halves was glued to a methacrylate cell with an epoxy adhesive (Figure 8, left). Additionally, three bentonite samples of 5.0 cm diameter and 2.2 cm height were obtained by uniaxial compaction of the clay. They were longitudinally cut in two halves using a Brazilian test apparatus. Those halves of the most appropriate size and consistency were stacked inside the methacrylate cell (Figure 8, right). Porous stones were placed on top and bottom and the cell was closed with stainless steel covers. Saturation proceeded from the bottom with deionised water, initially under a low pressure. Once saturated the cell GB1 was dismounted and weighed, to check the final bentonite
