Designed to produce the required 10" effective gauge length,
prism molds Molds feature removable partitions, base and end plates.
Effective gauge length is measured from inside end of the studs. Molds
produce cement prism specimens 11-1/4" long. Including studs, outside to
outside length of specimen is 11-5/8".



Applications include, but are not limited to:

Volume change tests of mortars.Autoclave expansion of Portland cement;
length change of mortar and concrete; potential alkali reactivity of
cement/aggregate combinations; linear change of magnesium and
oxychloride cements. Volume change of cement past; length change of
mortar and concrete.
