    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.

    Abstract: A container assembly comprises a container having a peripheral side wall defining a rectangular interior space and having top flap and bottom flaps folded inwardly to selectively enclose the interior space. The bottom flaps include notched edges for interlocking to maintain corners of the peripheral side wall square. An insert is removably receivable in the rectangular interior space. The insert comprises first and second panels of sheet material selectively folded to define a plurality of rectangular mold cavities in the interior space. Distal edges of the panels are notched wherein the notched edges interlock at the corners of the peripheral side wall to maintain the mold cavities square.

    Abstract: A concrete accessory for use with a ready mix chute comprises a funnel shaped hopper. The hopper has a wide upper opening of a size corresponding to that of a ready mix chute and tapering to a narrow lower opening. The hopper has a seamless inner surface and a pair of hollow aligned receptacles on opposite sides of the hopper and extending outwardly therefrom proximate the upper opening. An elongate rod has a length greater than the spacing between the aligned hollow receptacles to be received therein. A hanger assembly removably attaches the rod to a ready mix chute, in use, to support the hopper below the chute.
