... the CEC and SI), especially for the polymer-enhanced bentonite and bentonite that had experienced some cation exchange (Hosney and Rowe 2013). Hosney and Rowe (2013) reported that the difference in swell index of air-dried and oven-dried bentonite was 8–33% for untreated sodium bentonite and 15–100...
