Mechanical features of stabilized soils with low cement content

Abstract
Soil chemical stabilization with cement is a common technique to enhance the engineering and mechanical properties of in situ soils according to stress rates imposed by civil engineering projects. Usually, moderate quantities of cement are used, around 5 to 10% of the dry material. However, cement manufacturing is one of the biggest sources of greenhouse gas emissions, specifically carbon dioxide. For this reason, reducing cement content by a few percent in geotechnical structures built with cement stabilized soils (CSS) has a high environmental interest, particularly in view of the involved volumes of material. This work aims to contribute to a better understanding of the mechanical characteristics of stabilized soils with low cement contents. First, the mechanical behavior of a soil treated with 3% cement was studied for several curing times. Next, measured fracture parameters were correlated. Finally, these measurements were used to characterize the Mohr-Coulomb (MC) failure criterion. Results showed a high correlation between compressive and MC parameters. An alternative method for estimating MC parameters for CSS based on tensile and compressive properties was successfully checked. The proposed approach can be used to determine design parameters for geotechnical structures.
