Pressurizing the Cement Curing Autoclave
Cement samples being cured in the Cement Curing Autoclave are pressurized
by a hydraulic fluid, normally water. The initial pressure can be provided by a
hand or electric pump, or by an inert compressed gas, such as nitrogen. For
either pressurizing method, the pressurizing chamber and manifold should be
filled as much as possible with a non-compressible fluid, such as water. This
minimizes the time required to pressurize to the desired pressure and increases
safety.

Water Expelled as Lid is Closed
Either pressure source is connected to the open 1/8 NPT port on the needle
valve. After reaching the desired pressure, the needle valve can be closed and
the pressure source disconnected.
