Abstract

This study aims to evaluate the suitability of the Injana Formation clays for filling material in the Al-Hajaj area, Salah Aal-Din. The exposed rocks are Injana formation, in addition to the Quaternary Deposit. four stations were studied to determine their suitability as materials for dams. Geotechnical properties show that the type of clay is low plasticity clay, and the chemical analyses show that the ratio of total dissolved salts ranges between 1.35-3.45 %, while the ratio of gypsum content ranges from 0.22-0.29. In the last, the geotechnical properties of Injana clays are accepted as filling materials for earth-fill dams when compare with National Center for Laboratories and Construction Sciences, 2003, Building Materials Specification, Sorb /R5. The aim of this study is to estimate the geotechnical properties of the clay rocks including petrophysical properties and Chemical properties and know the viability of clays for filling dams in the study area as filler material based on Iraq specification, 2003, Sorb/R5.
