“…On the other hand, Type and fineness of the cement played a secondary role. According to Tsai and Ni [34], an adverse relationship was found between the shear modulus of the cement-treated soil and the shearing strain. However, the damping ratio correlated positively with the shearing strain.…”

In spite of soil treatment using Portland cement being well documented, it is hard to find all of the contents related to this topic in one document. This paper aims to provide information inventory about chemical and mechanical changes that take place in soil properties, and the alteration in engineering characteristics which occur in soil -cement mixtures. The mechanism of treatment over time is documented as well. Some conflicted results were detected in literature such as moisture -dry density relationship and dynamic properties of soil treated by cement. The suitability of cement as an additive for different soil types is discussed based on the results which were obtained by different authors. Based on the methodologies followed by laboratory and field studies, the mixture process involves deep and shallow mixing using cement as powder or slurry (grout). Finally, the paper discusses the sustainability of Portland cement as a manufacturing product. Generally, using cement as soil stabilizer induces a significant increase in soil strength, workability, and durability. Permeability and swelling potential are significantly decreased. In addition, a considerable improvement in soil compressibility is achieved for the soil -cement mixture. Negative environment impact is one of the major inherent disadvantages in cement production, where the cement production process is responsible for 5 -8% of the total anthropogenic CO 2 emission. Furthermore, high energy consumption, depletion of resources and weakness against sulfate attack, carbonation and organic materials effects are significant inherent disadvantages in cement-treated soil. So, partial or full replacement of cement by more sustainable materials is recommended.

“…In the case of expansive clay, lime cementation enhances static stability such as shear strength improvement and swelling reduction, as well as dynamic properties (Chae and Au 1978). Moreover, the threshold strain where the shear modulus begins to fall, increases with higher cement treatment, while higher cement content prevents rapid degradation of the G/G max curves at larger torsional strain levels (Tsai et al 2012).…”

Due to numerous environmental concerns in recent years, the search for and the development of sustainable technologies have been pursued. In particular, environmentally friendly methods of soil improvement, such as the potential use of biopolymers, have been researched. Previous studies on the use of biopolymers in soil improvement have shown that they can provide substantial strengthening efficiencies. However, in order to fully understand the applicability of biopolymer treated soils, various properties of these soils such as their dynamic properties must be considered. In this study, the dynamic properties of gel-type biopolymer treated soils were observed through the use of resonant column tests. Gellan gum and Xanthan gums were the target gel-type biopolymers used in this study, and the target soil for this study was jumunjin sand, the standard sand of Korea. Through this study it was demonstrated that biopolymers can be used to enhance the dynamic properties of the soil, and that they offer possibilities of reuse to reduce earthquake related soil failures.
