A STUDY ON VARIATION IN ENGINEERING CHARACTERISTICS OF SOME GRANITIC ROCKS

Rock characterization provides an important input data for the design of the structures founded on or in the rocks. This paper deals with the characterization of granite obtained from certain locations of Jabalpur and Bundelkhand regions were selected for sampling the physical properties and Unconfined Compressive Strengths were determined for the selected samples. It has been observed that there is a considerable variation in the physical properties like specific gravity, water absorption, dry and saturated densities and Unconfined Compressive Strengths of the rock samples of different locations. The laboratory test results reveal that the specific gravity and water absorption values vary from 2.60 to 2.75 and 0.2 to 0.35 respectively. The dry density vary 2.59 g/cm3 to 2.70 g/cm3. The Unconfined Compressive Strength has a variation from 120 MPa to 175 MPa
