Volume Change Behavior of Natural Expansive Soils Subjected to Acid and Alkali Contamination

Abstract Acid/alkali contamination of expansive soils, which has been probed in recent years, gives rise to unexpected structural failure when exposed. However, a systematic research aiming at evaluating volumetric behavior of natural illitic clays when subjected to acid/alkali solution as pore flui...
