All grease, oil, contaminants, ice or snow and foreign deposits
shall be removed from all surfaces with which the grout will come
in contact. The concrete surfaces shall be roughened to ensure bond.
Concrete foundations shall be kept wet for a minimum of 12 hours
before placing grout. All free standing water shall be removed from
concrete surfaces prior to grouting. For grouting of base plates,
the formwork used to contain the grout shall be constructed in a
workmanlike manner and caulked to prevent leakage of grout. Provisions
shall be made at high points for air to be vented as it is displaced
by the grout.
A mechanical mixer is recommended. The size of the mixer should
be appropriate for the volume of grout required. Mix NON-SHRINK
GROUT using clean water, only the minimum amount needed to obtain
the desired consistency. After all dry materials have been added
to the water, continue mixing for at least 3 minutes. Grout should
be placed within 45 minutes after preparation and it should be agitated
until use.
Water required per 25 kg (55lb)bag to make different grout consistencies:
Plastic grade = 3.78 L (1 gal) Flowable grade = 4.6 L (1.3 gal)
The prepared grout shall be transported to the forms and deposited
without delay. Vibration and agitation of the grout in the forms
is permitted. Grout having been prepared but not placed within 45
minutes after preparation shall be discarded. Prepared grout shall
be agitated until use. NON-SHRINK GROUT may be packed, poured or
pumped.
After finishing procedures, curing measures should be started as
soon as possible. Curing shall consist of the covering of all exposed
portions of grout with wet burlap for a minimum of 3 days or by
the application of a commercially available curing compound to the
exposed shoulders.
Yield: 25 kg (55 lbs.) bag will yield 0.45 cu.ft. at a flowable
consistency.
NON-SHRINK GROUT must not be allowed to freeze while setting. Do
not use the grout unless all surfaces with which it is to come in
contact are above 5°C (40°F). Warm water should be employed
under cold conditions and freshly placed grout should be kept at
temperatures above 5°C (40°F) for at least 72 hours.
Clean-up with soap and water as soon as possible after application.
Corrosive. May cause eye injury. If product gets into eyes, flush
repeatedly with water and seek medical attention promptly. Avoid
skin contact. If contact occurs, wash exposed skin with water. Protective
eyewear should be worn. AVOID CONTACT WITH EYES.
Cement when mixed with water results in a solution of calcium hydroxide.
If splashed in eyes or skin, flush thoroughly with water.
Silica sands which may cause lung cancer.
- For flowable applications mix no more material that can be
applied in 20 minutes.
- Smooth concrete surfaces should be roughed and old surfaces
should be etched.
