CHEMICAL RESISTANCE BothV-1®andStandardV-100®areresistanttochemicalsnormallyfoundin the industrialenvironment.This in-cludesoils,coolants,andotherfluids.AgoodruletofollowwithV-1® isthatif the concrete floor can be exposedtothechemical,thegroutcanbealso.ThisputsV-1® inaclassaboveotherproductsthatrequiresealingtomaintaintheirproperties.

ItisreasonabletoexpectV-1® groutto react as the concrete would tochemicals since after cure it is basi-cally sand and cement. Actually, it isoften more chemically resistant andholdsuplongerthantheflooraroundit.This isbecauseit isamoredensematerial than the concrete and thechemicalattackcannotpenetrate thesurface.Therefore,whiletheconcreteisbeingattackedfromwithin,thegroutisonlybeingetchedfromthesurface.Needlesstosay,ifitisknownthattheremaybesomechemicalattackandthefloorissealedtoresistthisattack,thegroutshouldalsobesealed.StandardV-100®alsooffersexcellentresistancetochemicalattack.

Physical properties shown are the result of independent labora-tory testing performed per industry recognized test procedures. Laboratory properties aid in determining suitability of the product for the intended application. Field test results may vary due to procedures or ambient conditions such as temperature and humidity. Laboratory reports are available on request.

Thegroutingofmachinebaseplatesandbearingplates,andofanchoring/alignmentequipmenttoafoundationarelow-costapproachesthatprovideahighqualitymachine-to-foundationconnec-tion.Asuccessfulinstallationdependson: propergroutselection,basedonapplication; foundation preparation;formingmethodemployed;andcarefulattentiontotheactualapplicationofthegroutingmaterial. Grout Selection—Selectinggroutfor a particular application should in-cludeanevaluationofthesefactors:1. Cost—Comparethecostofmixed

grout, ready for placement.Yieldscan vary considerably from onemanufacturer to another, and drypowder to price comparisons aremisleading,astheamountofmixingwaterrequiredwillalsovary.

2. Strengths—Applied loads shouldbe evaluated carefully to ensurethat the bearing capacity of thegroutisnotexceeded.Compressivestrengthsreportedbymanufactur-ers are based on tests run underlab conditions; actual field-curedvalues forcementitiousgroutswillbeapproximately80percentofthelabresult.

3. Ease of handling and placement—Thefollowingfactorsareimportant:A. Flowability.Theeasewithwhich

B. Tendency to separate whenmixedorhandledexcessively.Insomematerialsthatusemetallicadditives or have aggregatesofwidelyvaryingsizes,theag-gregatestendtoseparateifthematerialisovermixedorhandledexcessively.

C. Ability to be pumped or vi-brated, particularly on largerinstallations. Again, separationistheproblem.Theabilitytobevibratedorpumped isaprimeconcernwhengroutingcavitiesare small, when placement is

difficult,orwhengroutmustbeflowedlongdistances.

D. Expansion or non-shrinkprop-erties.Themainobjectiveistoselectamaterialthatwillexpandenough to assure full bearingcontactwithmachinebaseandfoundation (a few tenths to 1percentorsoisnormal).Whenlargegrout-to-machinecontactareasareencountered,agroutwithacontrolled internalpres-sure development should beselected toprevent thegrout’sexpansionfromdisturbingalign-ment.Theactual expansionofagroutistypicallymeasuredbyeither theASTMC-1090-88orASTM-C827-87 early volumechange method; the result isexpressedasapercentage.

E. Maintenance requirements. Whatwillberequiredtokeepthegrout functional in theenviron-mentintowhichitwillbeplacedisthemainconcern.Forexample,agroutthatistobeusedinanoily environment should be arelatively impermeable type. Agroutwithaporousstructurewillrequireapaintcoat topreventpenetration by oils and otherchemicals.

Otherspecialconsiderationsincludeabilitytowithstandthermalcyclingandhightemperatures,abilitytoresistacids,and susceptibility to spaulding underfreeze-thawcycling. Materials inusetodayrangefromslightly modified sand and cementmixtures to chemically sophisticatedepoxymaterialswithstrengthsfivetosixtimesthatofstandardconcretes. Cementitious Grouting Materi-als—The simplest grouting materialconsists of sand and cement mixedatapproximatelya50-50ratio.Simplesand and cement mixtures shrink oncuring,usuallyfrom2to3percent,mak-ingtheiruseinhighloadorprecisionapplicationsquestionable.Cementitiousgroutsinusetodayhavebeenmodifiedtoexpandratherthanshrinkoncuring.

1.Foundationformingandfinishingtolerancesmay be relaxed. Because grout providesthefinallinkbetweenthemachineandthefoundation,thefoundationisusuallyfinished11/2to3in.belowthedesiredmachinebaselevel.Athickerorthinnergroutpadcanbeused,as thespecific situation requires, tocompensateforthevariancesencounteredinactualfoundationconstruction,eliminatingtheneedforprecisionfoundationwork.

2.Groutingprovidesarigidmachine-to-founda-tionconnection.Asthegroutisplacedintothecavity,intheplasticorfluidstate,itconformsprecisely to the machine base and to thefoundation,providinga100percentbearingcontactbetweenfoundationandgroutpad,andgroutpadandmachinebase.

3.Anchoring/alignment equipment can bepositioned within a precast or core-drilledgrouting cavity at the time of machine in-stallation.Asthefoundationisconstructed,groutingcavitiesarecreatedbyprecastingorcoredrilling(whilethefoundationisgreen)attheapproximatelocationofeachsupportoranchorpoint.

This approach eliminates therequirement for time-consuming, precisepresettingofanchorboltsoralignmentequip-ment,significantlyloweringthecostofmorecomplexinstallations.

Forming Recommendations—Inpreparingformsforretainingfluidgrout,keep in mind that the most effectivemeans of achieving a good machinebase-to-grout contact is to place thematerial fromonesideonly.Thema-terial should flow under the machinebeinggrouted,and,whileitisflowing,contactbetweentheuppersurfaceoftheadvancinggroutandthemachinebaseshouldbemaintained.Thisapproachwillensurethatnoairbecomestrappedbetweenthegroutandmachinebase,Fig.1.

Fig. 1. The grouting material should be placed from one side only to achieve good machine base-to-grout contact. This approach ensures that no air is trapped between the grout and machine base.

Fig. 2. This application, recommended when leveling/alignment equipment is grouted, simultaneously providing a bearing pad and anchor bolt.

Fig. 3. If the anchor bolt cavity is very deep, an air bleed tube might be advisable. It should be withdrawn after the cavity is filled. An al-ternate approach is to use a funnel and hose. A highly flowable grout is required, and the tip of the hose should be withdrawn slowly as grout level rises.
