The object of this research is the behavior of soil mixing column.
The problem that this research aims to address is to better understand the behavior of soil mixtures under the effect of wetting-drying cycles (aging) and its impact on unconfined compressive strength.
The research consists of a parametric laboratory (experimental) research, with the preparation of different mixtures containing varying percentages of fine particles, cement, and water/cement (W/C) ratios. Eight different formulations were studied: a reference formulation, three formulations with 25% fine particles and different cement dosages, three formulations with 10% fine particles, and two with 5% fine particles. A reference sample was used to track the evolution of these results. This variation in mixture composition allows to observe the influence of particle size distribution, clay content, and cement content on the relative unconfined compressive strength of the prisms. The results show that the relative compressive strength of the prisms decreases by approximately 41% between 3 and 24 cycles, regardless of the cement content. It increases by 18 to 25% with increasing cement content for all formulations, but decreases by approximately 23% with increasing fine particle content. This research allowed to propose an equation to predict the evolution of relative compressive strength as a function of time, the number of wetting-drying cycles, cement content, and fine particle content. The various results obtained highlight the influence of fine particle and cement content on the performance and durability of soil mixing columns, and underscore the importance of conducting a thorough parametric research in the laboratory to facilitate the efficient and economical design of these columns.
