Bentonite in two-component grout applications
Bentonite 3, instead, was characterised by a markedly different value of SWI, 10 points higher than the other ones. Pertaining to LL, the test campaign to assess the liquid limits highlighted very high values, over 400% for all bentonites. Specifically, bentonite 2 exhibited the highest value while the lowest value was for bentonite 1. 7.
