Abstract

Presence of gypsum particles in soil may cause many problems in such different application as agriculture and construction. solubility causes the gypsum particles in contact with water, to be gradually dissolved and flow out of the environment. The structures built on these soils can be damaged due to solution of gypsum particles existing in the soil and collapse of the bed. In this research the effects of two factors including; gypsum content and hydraulic gradient were studied on solubility of gypsum containing clay soils. Samples of gypsum containing soils were provided artificially by adding various rates of natural gypsum including 0, 5, 10, 20 and 30 percent by weight of clay soil being prepared. Each Gypsum soil sample was leached under five hydraulic gradient levels of: 0. 5, 1, 2, 5 and 10. The results indicated that the rate of Gypsum present in the soil directly affects the rate of solubility in a way that by increasing the percent of Gypsum the rate of solubility was increased. Also the rate of leaching including the rate of derived Gypsum from soil to primary rate of Gypsum is decreased by increasing the rate of Gypsum. In addition, by increasing hydraulic gradient, the speed and volume of drained water through the soil increased in a specified time and thereby more gypsum particles washed out through the soil.
