Stuitability of Injana Clay For Filling Materials In Earth Fill Dams In Sharqat Distric/ Salah Alden North Iraq.

Abstract

The Study Aims To Study The Suitability of Injana Clays In North East Sharqat Governorate For Filling Materials In Earth Fill Dams. Three Stations Were Chosed Which Reflect The Study Area.The Laboratory Test Show Matching The Curve Of Zone (C) With The Curve Of Grain Size Analysis, The Ratios Of Liquid Limits And Plastic Limits Ranges Between (44.5- 47.155)% And (12.7- 19)% Respectively The Ratios Of Total Dissolved Salts And Gypsum Content Ranges Between (2.61- 4.1)% and (0.10- 0.21)% Respectively And According To Iraqi Standard Specification (SORB/R5 2003) The Clays Of Injana Formetion Are Suilable For Filling Materials In Earth Fill Dams.
