scabbling मीनिंग इन हिंदी

A typical scabbling machine uses several heads, each with several carbide or steel tips that peck at the concrete.
In modern construction, scabbling is a mechanical process of removing a thin layer of concrete from a structure, typically achieved by compressed air powered machines.
Scabbling is used to remove road markings, surface contamination ( used in the nuclear industry ), to add a decorative or textured pattern to concrete, or to prepare a concrete surface prior to the installation of grout.
