Designed and manufactured in strict conformance to ASTM standards, the 3-Gang 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.
