Effect of Carbon Nanotubes on the Acoustic Emission Characteristics of Cemented Rockfill
نویسندگان
چکیده
Abstract The use of carbon nanotubes (CNTs) to reinforce cemented rockfill is attracting considerable interest due the remarkable improvement in performance and extremely low dose added nanomaterial. To reveal enhancement mechanism CNTs on rockfill, acoustic emission (AE) characteristics specimens during Brazilian split test were investigated. results demonstrated that improved tensile strength by 17.2% decreased AE count. nucleation micropore-filling effects promoted cement hydration reaction formation a denser structure, thereby improving resistance loads. Meanwhile, finer pores avoid stress concentration, resulting activity becoming more sparse. Finally, b-value increased 14.8%, which further indicated overall failure process was at lower intensity.
