Abrégé anglais



Oil sands drill cuttings waste represents one of the most difficult challenges
for
the oil sands mining sector. Reducing the amount oil sands drill cutting waste
sent to
landfill offers one of the best solutions for waste management. The present
disclosure
provides cementitious formulations comprised of treated oil sand waste for use
in
geotechnical applications. The cementitious formulations include but are not
limited to
grouts, cement and controlled low strength materials (CLSM) and in these
formulations
the treated oil sand waste (TOSW) is used to replace conventional constituents
such as
some of the fly ash in concrete, some of the cement in grout formulations and
some of
the fly ash and cement in the controlled low strength materials. The treated
oil sand
waste is predominantly silicon dioxide (SiO2) which is produced using a
process and
system which separates water and oil from the solid waste, known as the
thermos-mechanical cuttings cleaner (TCC).


Note : Les revendications sont présentées dans la langue officielle dans laquelle elles ont été soumises.


THEREFORE WHAT IS CLAIMED IS:

1. A method of producing cementitious formulations, comprising:
subjecting oil sands drill cuttings to a process configured for
separating water and hydrocarbons from solid constituents of the oil
sands drill cuttings, and
producing treated oil sands waste comprising solid SiO2 particles
having a size distribution in a range from about 0.8 to about 30 microns,
and with about 90% of the sample volume below about 9.9 microns; and
mixing said solid SiO2 particles with constituents used in preselected
cementitious formulations used in a preselected geotechnical application.
2. The method according to claim 1, wherein the process configured for
separating
water and hydrocarbons from solid constituents of the oil sands drill cuttings
is carried
out in a thermos-mechanical cuttings cleaner.
3. The method according to claims 1 or 2, wherein the solid SiO2 particles
have a
mean size of about 2.7 microns.
4. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a grout formulation to be mixed with water, and wherein said
grout
comprises a mixture of at least cement and water, and wherein said solid SiO2
particles
are used to replace at least some of the cement.

52


5. The method according to claim 4, wherein the solid SiO2 particles are
used to
replace the cement in an amount between about 10 to about 50 % by volume.
6. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a grout formulation to be mixed with water, and wherein said
grout
comprises a mixture of at least cement, sand and water, and wherein said solid
SiO2
particles are used to replace at least some of the cement and sand.
7. The method according to claim 6, wherein the solid SiO2 particles are
used to
replace the cement in an amount between about 10 to 30 % by volume, and to
replace
the sand in an amount between about 10 to about 20 % by volume.
8. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a grout formulation comprising cement to be mixed with water,
and
wherein said solid SiO2 particles are used to replace cement from 0% to 50% by

volume.
9. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, aggregates and fly ash, and wherein
said solid
SiO2 particles are used to replace at least some of the fly ash.

53


10. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, aggregates and fly ash, and wherein
said solid
SiO2 particles are used to replace all of the fly ash such that said
cementitious
formulation for concrete includes cement, aggregates and said solid SiO2
particles.
11. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, aggregates and fly ash, and wherein
said solid
SiO2 particles are used to replace at least some of the fly ash and some of
the cement.
12. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, aggregates and fly ash, and wherein
said
aggregates include sand and gravel, and wherein said solid SiO2 particles are
used to
replace at least some of the fly ash, some of the sand and some of the cement.
13. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, aggregates and fly ash, and wherein
said
aggregates include sand and gravel, and wherein said solid SiO2 particles are
used to
replace at least some of the sand and some of the cement, and all of the fly
ash.

54

14. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a concrete formulation to be mixed with water, and wherein said
concrete
comprises a mixture of at least cement, fine aggregates, course aggregates,
fly ash,
and wherein said solid SiO2 particles are used to replace the sand by 0 to 40%
by
volume, and some or all of the fly ash.
15. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a controlled low strength material to be mixed with water, and
wherein
said controlled low strength material comprises a mixture of at least cement,
and fine
aggregates, and wherein said solid SiO2 particles are used to replace at least
some of
one or both of concrete and fine aggregates.
16. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a controlled low strength material to be mixed with water, and
wherein
said controlled low strength material comprises a mixture of at least cement,
fine
aggregates, and fly ash, and wherein said solid SiO2 particles are used to
replace at
least some of one or all of the concrete, fly ash and fine aggregates.
17. The method according to claims 1, 2 or 3, wherein the preselected
cementitious
formulation is a controlled low strength material to be mixed with water, and
wherein
said controlled low strength material comprises a mixture of at least cement,
sand, and
fly ash, and wherein said solid SiO2 particles are used to replace sand by 0
to 15% by
volume and fly ash by 100%.

18. A
cementitious formulation produced by the method of any one of claims 1 to 17.
