Cement Cube Molds

Designed and manufactured in strict conformance to ASTM and AASHTO specifications

1.   Wide flange design for mold stability and performance

2.   Precision machined forged bronze construction for accuracy and corrosion resistance

The Cement Cube Mold is used to form 2" (50.8 mm) cube samples for compressive strength testing of Portland cement, mortars, lime, gypsum and capping compounds. The main feature in the design is the wide flange construction of the top and base. This wide flange simplifies the striking off of excess amounts of cement when the cubes are being prepared and gives greater stability to the mold in storage, preparation and curing. The sturdy flanges prevent warping of the mold during use.

Warping has been the cause of cement cube molds losing their dimensions and angular tolerances. The molds use mechanical screw clamps to connect the two halves of the mold so they can be drawn tightly together. This same feature is important in removing cubes from the mold. With an unscrewing action on the clamps, the two sides of the mold can be drawn apart uniformly. This eliminates prying the mold sections apart with a trowel, knife or other sharp instrument, a practice which destroys mold surfaces and springs the mold out of tolerance.

The "T" bolts are held in place by snap rings, which precludes loss and allows for ready replacement should the "T" bolt be damaged. To facilitate cleaning of the mold, all of its surfaces are clean-lined and smooth.
