Prism Mold, Autoclave Expansion of Portland Cement

Designed to produce required 10″ effective gauge length, prism test bars. Molds feature removable partitions, base and end plates. Effective gauge length is measured from inside end of the studs. Molds produce cement prism specimens 11.25″ long. Including studs, outside to outside length of specimen is 11.625″.

Application: 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 paste
