2086749 9201214 PCTABS00010 An apparatus and method for providing a test sample (14) of concrete from a large poured area of concrete (11) includes a mold (12) placed within the concrete form (10) and having a continuous sidewall and a bottom wall. An insert (16) is spaced from the bottom wall so that a pressurization chamber (18) is formed between the insert and the botton wall. A fluid inlet tube (22) is connected to the mold in fluid communication with the pressurization chamber. A plurality of spaced apart legs (20) are formed on the insert to maintain the spacing of the insert from the bottom wall. Alternatively, the chamber can be filled with a noncompressible fluid. The test sample is removed from the concrete pour by pressurizing the chamber, and can then be taken to a laboratory and tested by conventional test devices.
