Mechanical and physicochemical study of a cemented sand exposed to wetting and drying cycles
Mechanical and physicochemical study of a cemented sand exposed to wetting and drying cycles
The core objective of this study was to analyze the impact of wetting/drying cycles on the mechanical behavior of a cement-treated sand. A comprehensive microstructural and physicochemical analysis were also performed to determine the physicochemical processes occurring in the samples along the cycles. Two types of wetting and drying cycles were applied to a 4%-cement treated sand. The results showed that although the cycles only slightly altered mechanical performance, they induced major mineralogical transformations in the cementitious phases. The results underline the importance of a protocol of imposing wetting/drying cycles for a more accurate assessment of the long-term performance of treated soils.
