Abstract

This investigation deals with a chemical stabilization program of expansive Esna shale, which widely distributed on the surface at the arid region along both West and East of Qena governorate, Egypt. Chemical stabilization program was applied to improve the geotechnical properties of the studied Esna expansive shale using both lime and cement kiln dust (CKD, as by product). Optimum-lime and -cement kiln dust (CKD) contents were measured using pH test according to Eades and Grimm method. Geotechnical tests of both natural and treated Esna shale samples as free swelling, ultrasonic velocity (Vp), and unconfined compressive strength (qu) were carried out. The results showed that the geotechnical properties of the studied expansive Esna shale samples mixed with CKD and/or lime were improved and stabilized. Also the results indicated that curing time increase from 7 to 90 days having a great influence on the improvement of the geotechnical behavior of the studied expansive Esna shale samples.
