Abstract: A perpendicularity verification device is provided for verifying perpendicularity of a concrete test specimen in a testing machine. The device comprises a unitary planar sheet. The sheet has an elongate vertical straight side edge and a horizontal straight bottom edge. The side and bottom edges are perpendicular to one another. A corner notch is provided between the side and bottom edges. In use, the bottom edge rests on a platen of the testing machine so that the notch circumvents a retaining cup of the testing machine and the vertical edge rests against the test specimen.

Abstract: A grout capping system is disclosed for capping a grout specimen in the form of a rectangular prism. The system comprises an alignment fixture having a base, an alignment plate and a spacer securing the alignment plate to the base. The alignment plate is vertically spaced from the base and has a notch forming a right angle inside corner adapted to receive a corner of a grout specimen. A capping plate comprises a body having a square recess of a size to receive the grout specimen. The capping plate is receivable on the base with a corner of the recess aligned with the alignment plate notch so that a grout specimen received in the recess maintains perpendicularity with the capping plate.
