Abstract: The indoor scale-down tests were done to study the law of dredged mud during self-weight sedimentation. The tests reveal that the configuration method of the dredged mud and the changes of sea salt concentration have great influence to self-weight sedimentation, the dredged mud which is used by the indoor scale-down tests should be configured by sea near the project, and the higher price of metal cations can accelerate self-weight sedimentation of dredged mud, and the appropriate amount of chemical additive can also accelerate self-weight sedimentation of dredged mud, and improve soil properties.

Abstract: The permeated grinding wheel was a new kind of grinding wheel, which was permeated by the chemical additives and solid lubricant into the interior gaps of the grinding wheel. Therefore, the grinding wheel can form a lubrication film on the surface of the grinding wheel. This grinding wheel has some good features, such as lower grinding temperature, smaller grinding force, higher life of the grinding wheel, and can prevent the adhesion of chip onto the grinding wheel surface. The experimental results indicate that the ground surface quality and grinding efficiency have been remarkably improved for more hard-to-cut materials.
