After remolding, a soil specimen is kept in an undisturbed state (that is, without any change in the moisture content) , it will continue to gain strength with time.

This phenomenon is referred to as Thixotropy. Thixotropy is a time-dependent, reversible process in which materials under constant composition and volume soften when re molded.

This loss of strength is gradually regained with time when the materials are allowed to rest.
