Stabilization of Clay Soil for the Durability of Structures: Case Study of the Soils of the Locality of Zalimé, Commune of Zogbodomey in the Republic of Benin

Structures erected on swelling clay soils are subjected to several stresses which at the origin of premature deterioration infrastructures. The being supports for works, improvement their weak characteristics with cotton fibers will not only increase bearing capacities these and resolution environmental problem, by eliminating CO2 produced burning stems after harvest. objective this study is contribute stalk powder used as foundation infrastructures in order guarantee durability. Identification mechanical parameterization tests were carried out raw soil samples taken 1.5 meters deep improved different levels (3%, 6% 10%). results from physical reveal that studied very plastic silt. As tests, it appears adding 3% dry density goes 1.435 t/m3 compared control sample a 1.50 t/m3; reflects an compaction studied. densities 1.445 1.29 10% powder.
