DESCRIPTION
V-1 Grout is composed
of graded sieve sizes of pure silica sand, high early cement, plus natural inorganic
and synthetic materials, blended under strict quality control standards for
consistent, uniform, high quality. Finished appearance is similar to concrete.
Volumetric expansion occurs within 24 hours after mixing with water. Thereafter
V-1 becomes completely stable, neither shrinking nor expanding. The limited
expansion and internal pressure development are achieved by a high-density crystal
formation during hydration.
USE
Grouting of: Turbines, generators, compressors, diesel engines etc. requiring
high strength and vibration dampening.
Anchor bolts, sole plates, bridge bearings, conduit, dowels, sleeves, hangers,
pipes, lighting standards and communication towers, signs and highway posts,
tanks, guard rails, etc.
Lathes, cranes, rolling mills, ball mills, paper, rubber and chemical processing
equipment, where high early strength and reduced down time is important.
Equipment subject to wide temperature variations, application in contact with
aluminum or magnesium or subject to stray electrical currents.
Structural steel columns, bridge beams and seats, craneway rails, transmission
towers, unbolted leveling plates and shims.
Applications subject to repeated freeze/thaw cycles, de-icing salts, or water
saturation; rock crevices, cracks and seams.
FEATURES
Controlled Expansion The
controlled volumetric expansion and internal pressure development prevents the
formation of harmful internal stresses and ensures a rigid, monolithic bond
between the surfaces being grouted. V-1 Grout is formulated to prevent shrinkage
below mixed volume from the time the specified amount of water is added to produce
any consistency from fluid to damp pack. No shrinkage during the initial set
- after hardening - after days or years.
Truly non-metallic (not just non-ferrous). Contains no cast iron borings or aluminum particles and therefore can be used in areas where products containing these elements cannot be employed. Successfully withstands fluctuations of moisture, dryness, heat and cold and may be used inside or out without unsightly rusting or the necessity of parging.
Totally non-corrosive V-1 does not contain chlorides, sulphides or similarly harmful chemicals which produce corrosive action and which are present in many other grouting compounds. It is also free from carbon, coke, fly ash or argillaceous materials.
High compressive, adhesive and pullout strengths. The compressive, adhesive and pullout strengths of a grout determine when loads may be applied to structural members or machinery which has been grouted. Early grout strength depends on the amount of mixing water used, the temperature during curing and the elapsed time after placement. Even at the highest recommended fluidity V-1 attains compressive strength of over 40 MPa (5800 psi) in 24 hours. The unique formulation of V-1 Grout results in an increase of compressive strength under vibrating and dynamic load conditions. The fineness modulus of V-1 Grout contributes to its strength and flow characteristics and enables the addition of selected aggregates which do not segregate nor reduce these characteristics.
Ease of installation. No special equipment or personnel are required for the installation of V-1 Grout. Handle as a "performance" concrete.
CAUTION
V-1 Grout is not normally recommended where the space under a base plate or
around an anchor bolt is less than 12.7 mm (1/2"). However, where only
dead loads and little stress is involved, 12.7 mm (1/2") may be sufficient.
Similarly, less than 12.7 mm (1/2") annular space but with compensating increased depth may be satisfactory for anchor bolt grouting where a shallow depth would not suffice. If in doubt, consult W. R. Meadows of Canada for technical assistance.
Do not employ extending aggregate for 12.7 mm (1/2") thickness or less. The basic rule is that aggregate size should be no greater than 20% of grout depth.
Do not use sand as an extender under any circumstances. Use crushed stone as an extender only in damp pack mixes or other placements where flowability is not a consideration, since the angular shape of this aggregate is not conducive to flowability. Consult W. R. Meadows of Canada for information on extending aggregates for specific installations.
Where grout may be exposed to sulphuric, nitric, hydrochloric or other acids corrosive to concrete, a seal coat may be required. Consider the use of CS-309TM, HIACTM or REZI-WELDTM 1000 by W. R. MEADOWS, depending on acid strength and temperature (see Data Sheets 3300-301, 3300-241, 3700-632).

Forming
Provide for rapid, continuous and complete grout placement. Use forms of sufficient
strength, closely fitted with joints sealed to prevent leakage. Coat forms with
a form release, (DUOGARD® by W. R. MEADOWS - Data Sheet 3150-112.) Do not
form tight to equipment - air may be entrapped.
Slant forms on the pouring side to avoid trapping air. Allow 76 mm (3") clearance for grout entry and up to 152 mm (6") "head". On the opposite side of the entry, allow minimum 12.7 mm (1/2") clearance between form and equipment and provide initially 25.4 mm (1") of grout "head" above the bottom of the equipment base plate. Reduce all grout "heads" to 3 mm (1/8") after initial set. Provide minimum 19 mm (3/4") grout thickness between foundation and base plate (see "Caution").
Temperature
V-1 Grout sets faster at high temperatures; slower at lower temperatures. Follow
normal winter or summer concreting procedures as appropriate.
Mixing
Use minimum water necessary to produce mix consistency desired. Detailed instructions
are shown on bag.
Mix grout in conventional mortar mixing equipment. First add 2/3 of the amount of water required, mix for a short period (until lump free) and then add the balance of the water. Mix for a further two or three minutes. Smaller quantities may be mixed using a blending propeller on a slow speed drill or may be hand mixed in a mortar box.
For deep grouting V-1 may be extended by adding up to 50% by weight of washed pea gravel (sizes up to 9.5 mm - 3/8"). (See information on bag).
Mix only enough grout for immediate use. If mixed grout is not placed immediately, agitate or re-blend just before placing. Re-blending or re-tempering is permissible within one hour after original mixing, depending on temperature.
Placement
Place by damp-packing, pumping*, pouring, rodding, strapping, chaining or vibrating.
To prevent voids, place grout from side or corner only, or, alternatively, place
excess grout which will be displaced by the weight of the object to be grouted
(e.g. leveling plate), to effect full bearing. Larger objects (e.g. large tanks)
may require use of shims.
* Contact Technical Sales for details on pumping.
Curing
Follow normal concrete curing procedures. Do not remove forms until grout is
sufficiently hard to avoid sagging.
Cover exposed material with wet burlap during the first 48 hours. Alternatively
use #1100, #3100, CS-309 or VOCOMP®-20 as membrane cure (see Data Sheets
3300-341, 3050-101, 3300-301, 3300-191).
Proper application is the responsibility of the user. Field visits by W. R. MEADOWS’ personnel are for the purpose of making technical recommendations only, and are not to supervise or provide quality control on the job-site.
