Abstract
Laboratory isothermal swelling pressure tests were carried out on compacted MX80 bentonite at 25 and 70 °C with distilled water as the hydrating fluid. Assessment of the swelling pressure was carried out using the electrical triple-layer theory for interacting clay platelets. An increase in the temperature reduced the swelling pressure of the bentonite on account of decrease in the Gouy-layer charge, mid-plane potential and distance functions. Agreements between the calculated swelling pressures from the triple-layer theory and the experimental results were found to be reasonable for compaction dry densities of less than 1.45 Mg/m3.
