F数值规范替代。FFandFLcriteriaisestablishedbyAmericanConcreteInstitute#117andCanadianStandardAssociation#A23.1tospecifyandmeasuretheflatnessandlevelnessofconcretefloor.Itcontains2values:FF-floorflatness,reflectingtheconvexandconcave,FL-floorlevelness,reflectinginclineandheightdifference.TheFvalueislinearrelationship.TheFvalueishigher,thefloorisflatter.F20is2timesasflatasF10,buthalfasflatasF40.F数值为美同混凝土协会(AmericanConcreteInstitute#117)及加拿大标准协会(CanadianStandardAssociation#A23.1)为规范及测量混凝土地坪平整及高差的标准。此规范包括两个F数值：FF为平整度，FL为高差值，平整度关系着地坪的隆起与凹陷.高差值关系着地坪的倾斜或高差。也就是说平整度FF表示地坪整体意义的起伏程度，水平度FL表示地坪整体意义的倾斜程度。愈高的F数值代表地坪的平整度愈佳。F数值为线性关系，因此F20比F10要平整2倍，却只有F40的1/2平。Diagram3FF/FLintervalforsuper-flatfloor图3　高平整度要求地坪的FF/FL区间Diagram4AmericanFloorPromodelⅧautomeasureinstrumentforflatnessand156

在清理干净的找平层上，依照室内标准水平线，校核一下地面标高和分格线。以所弹地干线为依据，设置支撑瓷片或瓷砖的地面木托板。加木托的目的是防止贴瓷片时在水泥浆未硬化的砖体下坠。木托板表面应加工平整。其高度为非整块瓷片的调节尺寸。整块瓷片的墙面铺贴，就从木托板开始自下而上进行。Mortarismadebyaratioof1:2(volume)forcementvssand,inwhich108glueismixedby3to4percent.Firstly,dilutethegluewithwatertwotimesthatoftheglueitself,thenputthemixturetothemortarforafurthermixing.Withashovel,themixtureisappliedtotheceramictileoritsback.Itshallnotbemorethan5mmintermsofitsthickness.Allitsfourcornersshallbeinclinedtoplaceandpressedbyhand,thenknockedbyrubberhammertoground.Itisnotedthattheglazedtileshallbefullygluedandleveledbyruler.调制糊状的水泥浆，其配合比为水泥:砂=1:2（体积比），另外掺加水泥重量3%～4%的108胶水。先将108胶用两倍的水稀释，然后加在搅拌均匀的水泥砂浆中，继续搅拌至充分混和为止。镶贴时，用铲刀将聚合物水泥浆均匀涂抹在瓷片或瓷砖背面，厚度不在大5mm，四周刮成斜面，按线就位后，用手轻压，然后用橡皮锤轻轻敲击，使其与底层贴紧，并注意确保釉面砖四周砂浆饱满，并用靠尺找平。Optionally,itcanbedonewiththemixtureofcementandgluewiththeratioof100:5.26.Thissortofmortarshallbefinishedallatonetime.Itisespeciallysuitableforwall,whichhasbeenleveledwithashpreviously.也可按水泥:108胶水:=100:5:26的比例配制纯水泥浆进行铺贴，这种水泥浆应随拌随用，并在收工前全部用完。它最适合底灰较平整的墙面。Beforethewalloflargesizeisworked,severaldiscardedceramictilesaretobelaidfortesting.Theyaretobeleveledbywoodenrulerorlevelrod.Onesignalpieceistobesetevery1.5minthehorizontaldirection.铺贴大面前，应先贴若干块废瓷砖片作为标准厚度块，用木靠尺和水平尺确定其两者间的水平度。横向每隔1.5m左右做一个标志块，将作为粘贴厚度的依据，以便在铺贴过程中随时检查表面的平整度。Thetilingislaidfromtoptobottomorfromrighttoleft.Usually,itisheldbythelefthand,whichfacilitatestheworkandprovidefullviewaswell.Oncearowoftilesisputtoplace,arectificationwithalongrodisrequired.Thosewhichareabovethesignalpieceshallbetappeddown.Thosewhicharelowerthanthesignalpieceshallberemovedandre-plastered.Itisprohibitedtoapplyplasteringdirectlyatthejoint,asitmayresultintobulge.Particularattentionshallbepaidwhileinterconnectingwithanotherrowofceramicstoensuretheyareflushedwithoneanother.Incasetherearedeviationsinspecificationorphysicaldimensionamongtiles,itisrequiredtoperformtimelyadjustmenttokeeptheyareunified.Therowaboveallshallbetiledinlineandtreatedwithtilesofarcincasethereisnobatten.156
