Abstract

A series of undrained triaxial shear tests was conducted on normally consolidated remoulded black cotton soil and kaolinite, in order to examine the influence of aging on their shear strength behaviour. It was found that apart from an increase in shear strength and brittleness, both soils exhibited an increase in their angles of shearing resistance when aged for a month. The cohesion intercept was found to reduce on aging. The initial tangent modulus increases very significantly (to the extent of even 10 times) especially for black cotton soil after 30 days of aging.
