Core Recovery and RQD (Rock Quality Designation) The easiest way to characterize the amount of material recovered during rock coring is to calculate “core recovery” as the amount
Strength and Modulus of Weathered Rock from SPT Values In the weathered rock it is difficult to drive the split sampler to the full specified depth as in
This method of rock classification was introduced by Deer & Miller in the year 1996. Two parameters are considered while classifying rocks on this method, which are Uniaxial
Classification Based on Degree of Weathering of Rock Mass Rocks can be classified on the basis of its degree of wreathing. These type of rock classification gives the
Modulus of Elasticity of Rock Modulus of elasticity of rocks depend upon several factors, such as, Type of rock Porosity Grain size Water content Value of modulus of
Rocks can be classified on site, on the basis of its physical appearance. By making a through visual inspection we can ascertain the engineering properties of rocks. Field
Rock Classification On the basis of genesis or mode of origin, rocks are classified into following three major groups. Igneous Rocks Sedimentary Rocks Metamorphic Rocks 1. Igneous Rocks
