This paper reports on the results of a laboratory investigation shear behaviour interface between granite rock and cemented paste backfill (CPB) reinforced with different amounts fibre (F-CPB) cured at room temperature for lengths time by performing direct tests. Moreover, various microstructural analysis techniques are also used to characterise degree cementation matrix, as well microstructure interface. The indicate that properties F-CPB/rock function content (optimal content) reduce...
The rapid development of global information technology, especially the emergence and widespread application Internet, has enabled technology to quickly penetrate into various fields economy society. Informatization networking have become important features today’s era. However, while people enjoy tremendous progress brought by humanity, openness security vulnerabilities computer networks also made network issues increasingly prominent. invasion hackers, continuous generation spread virus,...
A better understanding of the shear behavior interface between cemented paste backfill (CPB) and surrounding rock is critical for constructing cost-effective, durable, reliable CPB structures. In practice, CPBs suffer sulfate attack during their service life, as a typical cementitious material, itself has disadvantages, such high brittleness, easy cracking, insufficient durability, which restrict further popularization application technology. Thus, in this study, direct tests, electrical...
Cemented paste backfill (CPB)/rock interface shear resistance results in a spatiotemporal stress reduction CPB and thus affects the mechanical stability of structure underground excavations. To study distribution structure, an integrated model consisting cohesive zone for CPB/rock behavior multiphysics hydrating is developed. The predictability proposed validated against measurements from laboratory tests field studies. Thereafter, used to investigate influence curing time, stope geometry,...
