The Jolting Apparatus is used for making standard rectangular specimens measuring 40.1 x 40 x 160mm of Portland and Pozzolana cement mortar for determining transverse strength.

This machine consists of a mold table, which is seated on a rotating cam driven at 60rpm. The rectangular mold table is connected by two support arms to the spindle.

The three-gang mold on the top is clamped rigidly to the mold table using the supplied hopper. The hopper supports the mold while free fall of the table is stopped by the cam. The machine is supplied with one mold and hopper.
