Abstract

This paper presents an experimental investigation performed to evaluate the soil water characteristic curves of sand/Al-Qatif clay mixtures.  Al-Qatif clay is natural expansive clay widely spread in the eastern province of Saudi Arabia.  Detailed mineralogical and physical tests were performed on Al-Qatif clay for characterization.  Mixtures of sand and Al-Qatif clay were prepared with sand being the base material and with different clay contents (0%, 5%, 10% and 15%).  Test results indicate that the shape of SWCC curves changes from the unimodel to the bimodal form of soil water characteristic curve with the increase in clay content indicative of changes in sand/clay mixture micro-and macro-pores
