Abstract: This paper describes the results of a test program in which the setting and hardening of cement, bentonite-cement slurries, and attapulgite-cement slurries are monitored in the laboratory with mechanical-shear and ...

Abstract: Local strain effects are proposed as a source of shear strength reduction in cemented particulate media, shales, and heterogeneous systems. Shear strength degradation through local straining may arise from particle ...
