Industry:Mining
Core obtained by drilling into and through formations into which grout has been injected and allowed to set.
Industry:Mining
Core removed from a concrete structure by diamond core drilling and tested in a laboratory to determine the strength and other physical properties of the concrete. Also, core removed from a borehole drilled in search of oil and used to determine the porosity of the core and whether oil is present.
