Abstract:Change in the mechanical parameters of cohesion and internal friction angle with variations in cement content and curing time of cemented paste backfill (CPB) materials was investigated carrying out a series of experimental study. In this scope, shear strength and uniaxial compressive strength (UCS) tests were performed to find out the failure properties of CPB samples. According to the results obtained from this study, a new factor is suggested to use in the MohrCoulomb failure criterion to better fit the env… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
