    Documents.

    2.3-Formwork

    Supply forms and formwork, including accessories, as

    specified in ACI 30 1.

    2.4-Water

    Unless otherwise specified in Contract Documents, all

    water shall be potable.

    PART 3-EXECUTION

    3.1-Preparation 3.1.1 Prepare concrete surface on which grout will be

    placed to provide a minimum 0.5 in. peak-to-valley profile,

    remove all laitance and microcracking from the concrete,

    and expose coarse aggregate. Use only small hand tools or a

    small pneumatic hammer with 30 lb maximum weight with

    a moil or chisel point to generate the profile. Nail point tools,

    bush or bush head bits, large jack hammers, or pavement

    breakers shall not be used. The surface shall be thoroughly

    cleaned and protected from subsequent contamination. The

    concrete surface shall be saturated with water and main

    tained in a saturated condition for a minimum of 24 hours

    immediately before grouting.

    3.1.2 Clear debris, dirt, and water from anchor bolt sleeves, shear key pockets, and other areas to receive grout

    using oil-free compressed air or vacuum.

    3.1.3 For anchor bolt sleeves that are not specified to be grouted, clear debris, dirt, and water by oil-free compressed

    air or vacuum. Fill with nonbonding moldable materials as

    specified in Contract Documents.

    3.1.4 Install pins, dowels, or other means of controlling shrinkage cracks, edge lifting, or both, in areas of unre

    strained grout as specified in Contract Documents.

    3.1.5 The equipment base shall be inspected to ensure that grout can be placed beneath the plate without trapping

    air in unvented corners. The inside of the baseplate shall

    be inspected where possible for blind areas or obstruction

    of flow. Verify that a vent hole l /4 to l /2 in. in diameter is

    placed through the plate at the intersection of all crossing

    stiffeners and at each point where air may be trapped.

    3.1.6 Verify that grout holes for placement are located so that grout does not travel more than approximately 48 in.

    The grout holes shall have been placed so that grouting can

    be started at one hole and progress to other holes to ensure

    that the grout flows under all areas of the plate. Verify that

    holes for pumping grout are 3/4 to 2 in. in diameter and

    threaded for standard pipe threads. Grout holes for gravity

    assisted placement of grout should be 3 to 6 in. in diameter.

    3.1.7 Verify that baseplate and other metal surfaces have been prepared in accordance with the manufacturers'

    requirements for grouting.

    3.1.8 Inform Architect/Engineer immediately if equipment base would create issues with grout placement.

    3.1.9 Forms-Forms shall be rigid and sealed with tape, caulk, or similar material to prevent leakage. Forms shall

    extend at least 1 in. above the highest elevation of the grout

    material under the grouted element and shall be built so that

    the grout can be placed as continuously and expeditiously

    as possible. Forms may also be provided to prevent grout

    from flowing over the top surface of the equipment base or

    baseplate.

    3.1.10 Form coating-Forms shall be coated with compatible form oil or wax or lined with plastic or other

    suitable bond breaker or release agent. Do not allow form

    work coating to contact underside of the equipment base or

    concrete surface.

    3.1.11 Gravity flow applications-When grout is to be placed around the perimeter of a base, the forms shall be

    constructed so that a pressure head can be developed in a

    headbox on one side of the plate. The headbox shall begin

    2 to 4 in. from the baseplate and slope away from the plate

    at approximately 45 degrees and provide a minimum grout

    head of 12 in. The box shall be sealed to the form to generate

    the head pressure required to get the grout to flow to the

    opposite side. The form on the opposite side shall be 2 to 4

    in. from the plate edge and shall extend at least 1 in. above

    the bottom of the plate. On the side of the plate parallel to the

    direction of grout flow, the forms shall generally be less than

    1 in. from the plate but still allow air to vent from beneath

    the plate during grout placement.

    (ciCiJ American Concrete Institute- Copyrighted© Material- www.concrete.org

  • CEMENTITIOUS GROUTING BETWEEN FOUNDATIONS AND EQUIPMENT BASES (ACI 351.4-14) 5

    To install grout through grout holes, use a placement cone

    with a minimum grout head of 12 in. and sealed between the

    cone and the hole edge.

    3.1.12 Pumping cementitious grout-For placements where the grout will be pumped under the plate through grout

    holes in the form, the forms shall be at least 2 in. outside the

    plate edge on all sides. Minimum clearance under the base

    plate shall be 1.5 in. The forms shall extend at least 1 in.

    above the highest grout elevation under the plate.

    For placements where the grout will be pumped under

    the plate through a hose laying over the top of the form, the

    forms shall be spaced outside the plate so that there is no

    restriction of the grout flowing through the hose.

    3.1.13 Corners-Round or chamfer all corners. 3.1.14 Expansion joints-Place expansion joints every 3

    to 7 ft to intersect all inside or outside corners. Joints shall

    run the full width of pour, length of pour, or both. Seal joints

    with tape or caulk where expansion joint material abuts adja

    cent material.

    3.2-lnstallation 3.2.1 Unless otherwise specified, use mixers in accordance

    with the manufacturer's written instructions or as described

    in the Contract Documents.

    3.2.1.1 The mortar mixer shall have a metal shell with horizontal mixing blades. The mixing blades shall be angled

    so that adjacent paddle arms reverse the flow of the grout

    in the mixing drum during rotation of the horizontal shaft.

    The mixing blades shall have adjustable wiper blades that

    wipe the inner surfaces of the mixing chamber. The wiper

    blades shall be rubber or other flexible, wear-resistant mate

    rial that does not deleteriously react with the grout mixture.

    The wiper blades shall be adjusted to continuously wipe the

    curved inner surface of the mixing chamber below the grout

    level and the ends of the chamber. The horizontal shaft shall

    rotate the mixing paddles at 28 to 35 rotations/minute.

    3.2.1.2 The mixer shall be clean, prewetted, drained, and essentially free of hardened mortar and other foreign mate

    rial that can be removed with a trowel or by striking with a

    hammer.

    3.2.2 Batch and mix grouts in accordance with manufacturer's recommendations. The water content or consistency

    of the cementitious grout shall not exceed the maximum

    or minimum values determined from qualification tests

    or recommended by the manufacturer and shall not cause

    bleeding or segregation in the mixed grout. The mixing time

    shall comply with the manufacturer's recommendation. Place

    grout as soon as possible after the completion of mixing.

    If the grout must be held in the mixer after the completion

    of the specified mixing time, the grout shall be agitated at

    slow speed before dispensing. The time that a batch can be

    held shall be within the limits of the manufacturer's recom

    mendations. Placement shall not be attempted with any

    cementitious grout if the resulting consistency is outside the

    manufacturer's recommended range for the existing clear

    ances and flow lengths using the method proposed to install

    the grout. Once mixed to the right consistency, no additional

    water shall be added.

    3.2.3 Temperature ranges-Adjust the ambient temperature, grout temperature at placement, and temperature of

    foundation and baseplate within the temperature range

    recommended by the manufacturer.

    3.2.4 Gravity flow placements-All placements shall be made from one side and shall begin at one corner of the plate

    or skid and continue at that point until the grout rises above

    the bottom of the plate on the opposite side of the plate or

    skid. Move the placement point or portable headbox slowly

    along the plate from one end to the other or to the next

    expansion joint section. The placement point shall not be

    moved until the face of grout moves along the length of the

    plate on the opposite side. The headbox shall not be allowed

    to become empty once the grout rises to the bottom of the

    headbox. Grout shall not be placed at various locations

    along one side. Grout shall not be poured toward the center

    from opposite ends or sides. When using expansion joints,

    pour grout into the adjoining expansion joint area once the

    previous area is at least 50 percent full. Follow the manu

    facturer's recommendations for thick placements to control

    heat generation and shrinkage.

    3.2.5 Pumped placement-Pumping shall begin at the grout inlet nearest one end of the plate. Grout shall be

    pumped into that inlet until it flows up into an adjacent

    inlet and flows from the entire plate perimeter adjacent to

    the inlet. The pump line shall then be moved to the adjacent

    inlet and pumping continued. The pump line shall be moved

    to successive inlets until grouting is complete. Grout shall

    not be pumped into more than one inlet simultaneously or

    before grout flow has reached an adjacent inlet. When a hose

    or lance is to be used to pump grout under the plate, the hose

    or lance shall be inserted under the plate to the point farthest

    from the point of insertion. The hose or lance shall be with

    drawn as grout is pumped under the plate but the hose or

    lance outlet shall remain embedded in the grout. Dispos

    able hoses may be left in place, provided that they are full

    of grout.

    3.2.6 No forms, headbox, or grout (except spillage) shall be removed until the grout has stiffened sufficiently to ensure

    that the grout does not sag below plate level.

    3.2.7 Surface finishes-Finish surface in accordance with manufacturer's specification, or as specified in Contract

    Documents. If a troweled or broomed finished is specified,

    finish surface while grout is still tacky.

    3.2.8 Headboxes-Remove any grout headboxes after grout has set sufficiently. Do not plug or fill baseplate and

    void holes until the grout has set.

    3.2.9 After placement, the foundation and machine or equipment base shall be kept at a temperature that is

    within the temperature range specified for placing, curing,

    and strength development requirements for the grout. The

    temperature shall be maintained within this range until the

    grout reaches final set. After final set, the grout shall be

    protected from cold or hot weather conditions until design

    strength is achieved. The grout shall be cured in accordance

    with the manufacturer's written instructions. The tempera

    ture shall then be adjusted to ambient temperatures over a

    period of 48 hours.

    and grout with accepted coating material.

    3.2.13 Tension anchor bolts as specified in Contract Documents.

    3.3-Testing and inspection 3.3.1 Sample collection-Samples shall be taken every

    day and when any of the component batch numbers change

    during cementitious grout installation. Test samples for prop

    erties critical to the installation such as flow, wet density,

    bleed, and strength, using documented test methods appro

    priate to the type of grout, as cited in the Contract Docu

    ments and grout manufacturer's instructions.

    3.3.2 Inspect baseplates for movement beyond the specified tolerances. If movement has occurred, notify Architect/

    Engineer to determine resolution.

    3.3.3 Inspect the grout for softness. Inspect the grout for voids by tapping on the plate and listening for hollow sounds.

    3.4-Repair

    3.4.1 If voids are detected, fill voids according to manufacturer's recommendations. Recheck for voids. Repeat the

    void filling and checking as necessary to ensure no voids are

    present.

    3.5-Cieaning

    3.5.1 Immediately after grouting is completed, all tools and mixing equipment shall be cleaned using water or an

    approved solvent.

    3.5.2 All unused mixed grout materials and clean-up residue shall be disposed of in accordance with Contract

    Documents.

    graphs into the Project Specification because taking them

    out of context may change their meaning.

    G2. If sections or parts of ACI Specification 351.4-14 are copied into the Project Specification or any other document,

    do not refer to them as an ACI specification, because the

    specification has been altered.

    G3. A statement such as the following will serve to make ACI Specification 351.4-14 a part of the Project

    Specification:

    Work on (Project Title) shall conform to all require

    ments of ACI 351.4-14, "Specification for Instal

    lation of Cementitious Grouting between Foun

    dations and Equipment Bases," published by the

    American Concrete Institute, Farmington Hills,

    Michigan, except as modified by these Contract

    Documents.

    G4. Each technical section of ACI Specification 35 1.4- 14 is written in the three-part section format of the Construction

    Specifications Institute, as adapted for ACI requirements.

    The language is imperative and terse.
