Triaxial study of granites and limestones from north and south of Peshawar Basin, N.WFP Pakistan
Abstract
Determination of uniaxial and triaxial strength of different building stones is important both from practical as well as academic point of views. Triaxial testing is the most appropriate method which provides an identical field condition. In order to achieve this objective, granite and limestone from four different localities (Malakand granite, Shahbaz Garhi granite, Kohat limestone and Cherat limestone) were selected to carry out triaxial tests.
Four samples of each rock, having length-to-diameter ratio of about two were tested under confining pressure of 0-30 MPa range. The observations made and results obtained are plotted and after drawing Mohr’s envelope for each rock shear strength is calculated corresponding to different triaxial confining pressure.
The findings of the study are summarized in the form of conclusions and recommendations at the end of the manuscript.
