8. Continue to pour cement in test cell until level is 1/4 inch (6mm) below the circular lip in
the cylinder. Use the Slurry Level Gauge to obtain the proper fill level. The slurry
should touch the lower tab marked WET but not touch the upper tab marked DRY. Do
not overfill the test cell, or cement will be forced into the pressure and/or thermocouple
ports, and plug them.
9. Use a small amount of water to continue filling the cell up to the water fill line indicated
on the slurry level gauge.
10. Screw the top plug into the top of the cylinder. It is recommended that the plug be
screwed in by hand and that the plug be tightened so that it just contacts the cylinder.
Further tightening after the plug has contacted the cylinder will not cause more effective
sealing, and will cause plug removal difficulty.
11. The test cell is ready to be installed in the heating jacket.
12. Wipe the cylinder assembly clean and place in autoclave chamber. Carefully guide the
bottom transducer cable through the bottom of the heater assembly and out the front
panel of the instrument. Be certain that the cylinder is not sitting on the cable. Do not
crimp the cable in any way since it can change the signal characteristics. Connect the
cable to the connector on the front panel.
13. Align the pressure port in the top plug with the high-pressure filter on top of the
autoclave assembly. Rotate the cell clockwise to align.
14. Position the filter with the arrows (located on the side) pointing in the downward position
and attach the short end of the U-tube connection to the top of the filter, as shown in the
picture.
15. Attach the filter assembly into the bulkhead located on top of the instrument.
16. Connect the longer end of the tube into the top of the
cylinder. Hand-tighten initially to start the threads, then
use a 5/8" wrench to tighten.
17. Connect the top transducer cable to the BNC connector
labeled Top Transducer at the back of the autoclave.
18. Install the thermocouple in the other high-pressure port in
the top plug. Hand-tighten only.
19. Connect the thermocouple cable to the receptacle labeled
J Thermocouple at the back of the autoclave.
20. Turn ON the water supply switch until water exits the
thermocouple vent hole. Tighten the thermocouple
connection using a 5/8-inch wrench.
Note: Use a rag or paper towel to catch water that exits the
thermocouple vent.
21. The test cell and autoclave are now ready to begin a compressive strength test.
