Physico-chemical changes in the lime stabilization of black cotton soil (India)
Abstract The paper describes the physical and chemical changes involved in the process of stabilization of Indian black cotton soils with lime. Mechanical analyses of clay-lime stabilized mixtures indicate that with small concentrations of lime, clay particles (less than 0.002 mm) only reacted to aggregate into particles of a larger size (0.02–0.05 mm). With the addition of more lime, the particles previously aggregated react further to form particles of a size larger than 0.075 mm. Some preliminary work on the chemistry of lime stabilization of black cotton soil indicates that the aggregation of clay particles with calcium hydroxide is very intimately connected with the hydroxyl groups. Similar behavior is observed for other alkaline earth metals falling under group IIA of the periodic classification.
