Abrasive grains held together with a hard, durable bonding material make grinding wheels, abrasive stones, and sticks. Abrasives can also be applied on fibrous sheets, paper, or cloth with the principle materials being aluminum oxide and silicon carbide. Crushed diamonds called Bort are also used as abrasive grains.

Which Grinding Wheel Should I Choose?
· Also, choose a finer grit when the project requires a closer, more precise operation over a smaller area of contact. Hard and potentially brittle materials such as glass, tool steel, and cemented carbide are most suited to the finer gritted abrasive. What grinding wheel grade should I choose? The grade indies the relative holding power of the bond, which holds abrasive grains in a wheel ...

Vibratory Surface Compaction
Vibroflotation is used for insitu compaction of thick layers of loose granular soil deposits to depths that may exceed 30 metres. In loose to medium dense saturated sands, the strong ground vibrations in the immediate vicinity of the probe will result in an increase of porewater pressure in the soil column surrounding the vibratory probe.
