Concrete Cylinder Molds Plastic

FORNEY has a wide range of single-use cylinder molds for fresh concrete testing. All molds are seamless plastic and can be stored for long periods with no deformation. Molds are available with integral lids or with reusable lids that can be purchased separately.

Not sure whether to use a 4” or 6” test cylinder mold for your project? If a project doesn’t specify a size, your choice between 4” and 6” test cylinders depends on the aggregate size in your mix. The cylinder must be at least 3 times the size of the aggregate in your concrete mix -  1” aggregate - use a 4” x 8” cylinder, 1.5” aggregate, use a 6” x 12” cylinder.
