Abstract
The phenomenon of soil swelling has been known for a long time. As construction grew in arid and humid regions, the problems associated with swelling and fearful soils began to receive more attention, a significant quality of research began to focus on expansive soils. Algeria is fully concerned by the problem of swelling clays which are presented in the different regions of the country. The swelling phenomenon affects various types of structures each year (light buildings, pavements, etc.) causing considerable damage which necessitates very costly underpinning operations, the construction of which is often not controlled. Before starting any work and before treating the soil and using it as a construction material, it is essential to know the general principles governing their behavior as well, the problems that it may pose. Indeed and for the improvement of swelling soils, we studied in this work the improvement of the behavior of a clay soil by the addition of two types of waste, kiln dust and wood chips. An experimental protocol in the laboratory was followed, the results found indicate that the two additions play a very favorable role in the stabilization of the swelling of the soil.
