Abstract
The laboratory evaluation of four sandstones from three projects, Shwezaye H.E. Project, Myanmar, Ujh H.E. Project, J&K, India (two variants) and Ken- Betwa Link Project, M.P., India, is presented here. The study leads to three broad inferences: one, there could be very large variation between two sandstones; e.g., here, sandstone from Ken-Betwa, vis-à-vis other three (comparatively poor) sandstones, is superior in all respects (except grain density). Two, the three poor sandstones differ in respect of some – not all – properties and parameters. Three, none of the three poor sandstones is better than the other two in respect of all properties and parameters. In respect of individual properties, the grain density of all four sandstones is similar, though their bulk densities, apparent porosity and slake durability index show great variation. The weak and strong sandstones show qualitative difference in their uniaxial compressive strength (UCS) and wave velocity (compression and shear, both); and the two are directly proportional. The study clearly demonstrates that there is no one-to-one correspondence between any two properties and parameters, but there is a diffused and/ or qualitative relationship between different sandstones, or certain properties and parameters of a particular variant.
