Experimental Study on the Sol-Bentonite mixture stabilized by different types of Polymers

Coherent soils are very responsive in nature and are part of many human activities. They change in volume considerably with changes in moisture content. These soils are characterized by the presence of a large proportion of highly active clay minerals of the montmorillonite group which are responsible for the pronounced volume change capability of the soils. The objective of this paper is to investigate the influence of different polymers on the plasticity properties of swelling clays. A study of their physicochemical properties based on an experimental protocol in the laboratory was carried out, the results obtained showed that the addition of the different types and amounts of polymers favourably influences the behaviour of expansive soils and reduces swelling.
