PAC-IT®
EXPANSIVE DRY PACK GROUT
Provides an easily workable, non-ferrous,
non-gaseous, non-shrink grout application where the use of forms is impractical.
SEALTIGHT PAC-IT Packable Grout is a non-ferrous, non-gaseous, non-shrink grout
formula specifically developed for its excellent workability and application,
where forms are not required.
Technical Description
SEALTIGHT PAC-IT Packable Grout is a non-ferrous, non-gaseous,
non-shrink grout specifically formulated for grouting where the use of forms to
contain the grout is impractical (such as in vertical or overhead applications).
PAC-IT is a premixed, low-slump, non-gaseous grout offering high density and
strength. PAC-IT offers excellent workability and high one-day strengths in
addition to the non-shrink property.
Uses
PAC-IT is ideal for grouting column bases, precast walls, panels,
beams, pretensioned or post-tensioned prestressed member applications.
Advantages and Benefits
 | Furnished premixed...ready-to-use...just add water
| Offers high density and high one-day strengths with
non-shrink characteristics
| Mixes quickly and easily to desired consistency right
on the jobsite
| Features excellent workability
| Requires no separate bonding agent...bonding agent is
an integral part of the bag's content
| Forms are not required
| Saves time and money |

* Set time and strength
development is dependant on temperature, therefore, follow ACI Methods
during hot or cold weather grouting.
ACI 305R-91 "Standard on Hot-Weather Concreting
ACI 306R-88 "Standard on COld Weather Concreting" |
Application Tools
Concrete Mixing Pan |
Mortar Mixer |
Pointed Trowel |
Hammer and 2"x 4" (for rodding) |
Application
All grouting should be done using
established concreting procedures according to American Concrete Institute
reccommendations: ACI 351.1R-93 "Grouting for Support of Equipment and
Machinery."
SURFACE PREPARATION: All grout surfaces must be clean, dry
and completely free of laitance, oil, grease, other coatings and any other
contamination. Unsound concrete must be chipped out, leaving surface level, but
rough. Grout area should be saturated surface dry (SSD) prior to grouting.
Remove excess water before grouting.
MIXING: Small quantities of PAC-IT Grout may be hand mixed in a concrete mixing
pan until lump-free. For large quantities, mix using a mortar mixer with
rubber-tipped blades for a minimum of 3 minutes. Use minimum water required to
produce desired placement consistency.
| |
Appropriate requirements per bag: |
| |
7 pts. (3.3 liters) for stiff
consistency |
|
8 pints (3.79 liters) for plastic
consistency |
Mix in 2 steps...add 2/3 of water requirement...add grout...after partial
mixing, add remainder of water for desired consistency. Thoroughly mix total
quantity for 3 to 5 minutes.
Do not mix more than can be placed in 30 minutes.
PLACEMENT: PAC-IT can be placed by packing or rodding.
CURING: If utilized, forms may be removed after grout has hardened to final set.
Prevent rapid loss of water by covering with wet burlap during first 48 hours or
apply appropriate SEALTIGHT Curing, or Curing and Sealing Compound. (We suggest
SEALTIGHT 1640-WHITE or CS-309-1315.
Coverage
Each bag of PAC-IT yields 0.43 cubic feet (0.012 cubic meters) of
in-place grout using the water ratio level shown above. Note: For grouting
application requiring a more flowable material, use SEALTIGHT 588 Non-Ferrous,
Non-Shrink Grout.
MAXIMUM ECONOMY FOR LARGE AND DEEP APPLICATIONS
Cost reductions can be realized when grouting large areas by the addition of
washed, dried and graded pea gravel. For thickness over 2"...add up to 25%,
3/8" pea gravel.
Packaging
50 lb. (22.68 kg) moisture-resistant bags
Storage
Store indoors off the ground. Keep dry for a shelf life of 12 months.
If material is hard or contains lumps, discard in appropriate manner.
Precautions
Refer to Material Safety Data Sheet for complete Health and Safety
Information.
