Soil is one of the most important materials used in a variety of construction projects including earth canals and earth dams. Nowadays, considerable attention has been paid to the utilization of alternative materials, which bear higher engineering quality than traditional materials and are financially affordable. High swelling soils have good plastic properties so that increased moisture results in their decreased strength and increased volume. These damages typically take an irreparable toll on structures, which further clarifies the importance of soil improvement. Considering millions of tons of waste produced annually across the country, which not only poses the problem of disposal but also adds to environmental contamination and health risks, utilization of such refuse and industrial wastes and their subsidiary products as alternatives to construction materials may effectively contribute to environmental preservation and minimization of their adverse effects on the environment. In the present study, eggshell powder and glass powder were used as the wastes, to combine with soil so that the properties of clay soil were investigated in different mixture proportions. Then the properties of soils including liquid and plasticity limits as well as plasticity index, dry density, optimum moisture content and unconfined compressive strength, which were already measured, were compared with those of the experimental specimens mixed with eggshell powder and Quarry dust in different proportions. Since the introduction of egg shell powder and glass powder improves the engineering behaviour of soils, this review work exposes those qualities and applications that make Quarry dust and egg shell powder a good replacement or admixture during soil improvement and for a more economic approach. The conclusion drawn from this investigation is that the combination of Quarry dust and egg shell powder is more effective than the addition of Quarry dust or egg shell powder alone for the improvement of properties of clay.
