Abstract
This article addressed the results of an experimental study that dealt with the behavior of recycled soil treated with lime and exposed to wetting- drying cycles at the long term. The object of this research was to focus on the effect of a wide range of lime content on evolution of volume and durability of stabilized soils, when exposed to wetting- drying cycles. In this work, an experimental study was performed on soils which were treated with 8 rates (0–8%) of lime. The treated soils were conserved for three different periods of cure: 7, 28 and 180 days, and then exposed to 12 wetting-drying cycles of 48 h for each cycle. However, the behavior under wetting-drying cycles was only satisfactory for lime percentages above 6%. The formation of C-S-H and C-A-H responsible for the increased strength of stabilized soil samples are showed and the expensive ettringite was also responsible for the decreased strength of stabilized soil samples.
