Effect of Moisture and Confining Pressure on Mechanical Behavior of Shiwalik Sandstone
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
The study for the effect of moisture on Shiwalik Sandstone has been carried out considering the different hydroelectric projects running in the foothills of the Himalayas. The strength of the rock depends upon its mineralogical composition, arrangement and orientation of grains, its physical and mechanical properties. For the proper accomplishment of the objectives different tests were conducted on the Shiwalik Sandstone sample. Results show that the rock is a soft rock. The porosity of the rock obtained by the testing is quite high which shows that the rock becomes weaker by the ingress of water. Voids are clearly visible through the scanning electron microscopy. And so the fatigue behavior of rock is affected by the varying confining pressure.
