Soundness of Portland Cement by the Autoclave Method

Specimens are cured in a high-pressure steam vessel and the change in specimen length is determined using Drying, Shrinkage and Moisture Movement Apparatus. The Autoclave provides high pressure steam curing of the specimens. The unit conforms to the requirements of ASTM. Supplied complete with safety valve, pressure gauge and thermostat controlled heater unit.

Special Note:
This unit draws a current of 20 amps.
