An unbonded capping system is provided for compression testing of grout samples in the form of rectangular prisms. The capping system comprises first and second retaining cups comprising metal blocks each having opposite parallel planar surfaces. A first of the planar surfaces is engagable by a test platen, in use. A second of the planar surfaces has a rectangular cavity for receiving one end of the grout sample. First and second rectangular compression pads each have a hardness in the range of about 50-70 durometer. The compression pads are of a size slightly smaller than a size of the rectangular cavities to be received therein to distribute a test load from the test platens to the grout sample.
