Sabkha is used to define salt-encrusted flats is composed of sand, silt or clay soil. It is found all over the world especially in areas with arid and hot and where the evaporation rate substantially exceeds the precipitation rate. Sabkha covers about 10% of earth surface. However, sabkha soil has a low shear strength and low compressibility. Soil improvement techniques are extremely required to enhance physical and mechanical properties of sabkha. On the other hand, marble waste is a challenge that need sufficient and urgent attention. The production of marble worldwide is roughly about 500 million tons. During process of marble cutting, grinding, and polishing, approximately 20-30 % of the marble blocks becomes a waste. This research is aimed to get rid of this waste material by utilizing it for stabilization of sabkha soils. Sabkha samples were collected from Al-Auzayba, Oman. The soil was treated by two binders: cement and cement-marble waste in dosages of 0, 2.5, 5, 7.5 and 10% of dry mass of sabkha. The percentages of marble powder in the cement-marble were 0, 10, 20, 30 and 100%. Physical properties and chemical properties of the mixture were determined
