ABSTRACT:
A core sampling device of the type utilized in forming concrete test cores in situ including a double-walled sleeve which is placed into the wet, fluid concrete in combination with an insertion tool whereby the sleeve, due to its configuration, may be pressed or "screwed" into the fluid concrete. By virtue of the double-walled construction of the sleeve, once the concrete has cured, the test core may be easily removed therefrom.
