Abstract :The mineralogical, and engineering properties of the problematic soils are well related to the problems of these soils. Extensive researches have been carried out to reduce the damages that may occur for building built on, or in problematic soils. There are numerous types of additives that mixed, added, or blended to soils to amend their poor properties. Some of these additives are conventional materials and widely used like cement, lime, chemicals, and produced materials. In the last decades, different waste materials from domestic and mineral wastes have been used to amend the problems of soils. This review paper presents different domestic and mineral wastes materials (e.g., Glass Cullet, Plastic Wastes, Waste of Tire, Fibers, Egg Shell, Marble Dust, Jarofix waste, etc.) as soil additives, where the uses of these wastes have important benefits (economic and engineering). The effects of these waste materials on soil geotechnical properties (include physical and compaction characteristics, strength and bearing ratio, and swelling and compressibility of soils) have been shown and discussed. The content used of these waste materials was studied, it looked widely varied from one research to another. This content is low in materials like waste plastics and fibers, while the content may reach more than 30% in the rest materials. The domestic and mineral wastes reduce the undesired soil properties like soil plasticity, swelling properties, and compressibility to varying degrees. While the shear strength, bearing ratio, stiffness, and compaction properties increase with the addition of these waste materials. However, some domestic and mineral wastes show more efficiency to stabilize the soils.
