TempGuard™ Polystyrene Concrete Cylinder Mold

Model: HM-338C
Price: $51.00

HM-338C TempGuard™ 4x8in (102x203mm) Reusable Cylinder Mold reduces the potential impact on concrete strength tests from hot or cold temperature swings during the initial curing phase, allowing consistent test results that more closely represent job-site conditions. Has unique insulating qualities that offer protection from both hot and cold temperature fluctuations on the job site.

The Polystyrene mold body is suitable for an average of six uses when the Plastic Liner is replaced between each use. Plastic Liner, each with side and bottom pieces, is inserted into the 4x8in (102x203mm) expanded polystyrene mold when casting fresh concrete specimens. Concrete specimens are removed using gentle application of compressed air through an opening in the bottom of the mold. TempGuard™ Cylinder Mold is supplied in a case of nine molds with pre-installed liners, plus 45 additional Liner Sets.
