ACE Mix Cement (6 gallon) Kit Mixing Procedure
Kit design: One pail containing Premium Class “H” Cement with proprietary blend of additives separated into two bags each yielding 3 gallons of slurry packaged in a seven gallon pail. Also included in kit are Defoamer, Retarder, ½ gallon pail, and a 60 cc (ml) syringe. Domestic kits have a second pail containing required amount of water.
Slurry Density: 16.4 lb/gal
Kit Yield: 6 US gallons
Water Requirement: 3.0 US gallons (11.4 liters) Fresh Water
- Measure BHT accurately prior to running cement.
- For best results, the temperature of the dry blend and water solution needs to be 70°F or above prior to mixing. Storage indoors recommended.
- For best results, use high speed mixer with rpm > 550 (under load) to sufficiently shear cement while blending.
- The kit may be mixed in a 3 gallon or a 6 gallon batch, follow guidelines related to desired batch size.
- The ACE Cement Kit is designed to allow addition of specialty add-in components (known as “Wild Cards”, see Table 3) to accommodate unique well conditions without having to purchase a separate special kit. Wild Cards come in packet form with their own mixing instructions stating proper mixing order and any required change in water or retarder concentration. If using a Wild Card, read and follow the instructions provided with the Wild Card product to insure proper mixing order and procedure.
Table 1: Retarder Amounts vs. Temperature
| BHT (F) | (3) Gallon Batch | (6) Gallon Batch |
| 100-149 | None | None |
| 150-190 | 11 cc (ml) | 22 cc (ml) |
| 191-200 | 27 cc (ml) | 54 cc (ml) |
| 201-210 | 44 cc (ml) | 87 cc (ml) |
| 211-220 | 60 cc (ml) | 119 cc (ml) |
| 221-230 | 76 cc (ml) | 152 cc (ml) |
| 231-240 | 103 cc (ml) | 206 cc (ml) |
| 241-250 | 136 cc (ml) | 271 cc (ml) |
| 251-260 | 179 cc (ml) | 358 cc (ml) |
| 261-270 | 206 cc (ml) | 412 cc (ml) |
| 271-280 | 239 cc (ml) | 477 cc (ml) |
| 281-290 | 255 cc (ml) | 510 cc (ml) |
| 291-300 | 271 cc (ml) | 542 cc (ml) |
Step 5: Mix until the retarder is completely dissolved, but a minimum of five minutes. This is now your mix water to be used to make the desired amount of 16.4 lb/gal slurry.
Step 6: If mixing total contents of kit, add both dry blend bags (sequentially) to the mix water containing retarder while high speed stirring. To mix a 3 gallon batch, add only one bag of the dry cement blend to the mix water containing retarder, while it is being stirred. Take care in adding the cement blend slowly (over a time period of approximately three minutes) into the mix water to allow for proper hydration of the cement and to prevent screening out of lumps of cement.
Step 7: After completing Step 6, stir with high speed mixer (recommend to use pneumatic type) for 10-minutes.
Step 8: Pour the cement slurry through a screen or grate to ensure that there are no large particles left unmixed in the slurry. Verify density with a mud scale. Note: A non-pressurized mud balance may cause the slurry density to appear slightly (+/- .2 ppg) less than the actual density. If it is desirable to mix cement slurry to a lower or higher density, call TTS for Technical Support and information. Note: The slurry will be thicker than 16 # slurry.
