DESCRIPTION
GYP-SET is a low strength gypsum based cement to provide the user with a grout having a predetermined set time. GYP-SET has a variety of applications and is provided with 30 and 60 minute set times.
APPLICATIONS/FUNCTIONS
GYP-SET is ideal for cementing unstable caving formations, for setting plugs for wedging and for plugging off to help seal voids, cracks and fissures that cause lost circulation. GYP-SET can also be used for cementing in surface casing where quick setting low strength cements are suitable. GYP-SET set times are encoded into the product so it’s vitally important the application and set time are carefully considered.
ADVANTAGES
- Controlled setting times
- Reduce rig time while ‘waiting on cement’
- Enable to maintain bore trajectory
- Easily mixed and pumped
- Aid to cure lost circulation
- Cements in surface casing
- Note alkali based
PHYSICAL PROPERTIES
- Appearance: Odourless white power
- pH (as supplied): 7.5 – 8.5
- Specific gravity: 2.6 – 2.7
- Bulk density: 0.028 – 0.029 Ib / in3 (bulk)
RECOMMENDED TREATMENT
GYP-SET will perform optimally when slurried in fresh water. GYP-SET will set hard in 30 and 60 minutes after mixing so it’s important to prepare prior to mixing and pumping. It is recommended a rubber cementing plug be pumped either side of the slurry to avoid contamination and to wipe residue from the rods.
GYP-SET should be mixed at a ratio of 35.27 Ibs GYP-SET to 2.64 gallons of water, blended until the slurry is consistently smooth.
