Geotechnical properties of weak rocks of Central India as construction material
Abstract
Engineering properties of weak rocks have been determined as per Indian (ISI) and International (IS) standards on cubes of 10 cm X 10 cm X 10 cm and NX size drill cores having L:D ratio of 1:1 and 2:1. Tests on 2:1 size samples needed correction to bring at par with ISI, and these values also provide fairly accurate data for application with values of 10–15 # more than I.S# Hence, the values given in the text as per ISI may have to be reduced by 10–15 % while correlating with I.S. The tests include specific gravity, porositv, crushing strength (dry & wet), absorption, modulus of elasticity, impact and abrasion values, permeability etc. Central India coversan area within and around the states of Madhya Pradesh and Maharashtra.
