Soil Improvement by Mixing: Techniques and Performances

AbstractSoil treatment and stabilization by mixing, an economic and eco-friendly method, is a technique that is increasingly being used worldwide in order to improve soft soils. A better understanding of the physical and mechanical properties and behavior of the final product is of vital importance for optimizing the design of the mixing process, thus for further development of the mixing methods, there is a need for more extensive laboratory research. The overall objective of the study presented in this paper is to improve the understanding of some of the important aspects of the strength behavior of stabilized soils. An experimental program was carried out in the laboratory on different artificial soils, comprised of clay and sand stabilized with cement, in order to determine the unconfined compressive strength, flexion strength, porosity, density and dynamic modulus. The results of the tests are presented in relation to results obtained by other researchers, available in the literature
