地面硬化剂施工方案及保护措施Constructionconceptforfloorhardener1）、硬化地面对新浇混凝土的要求Requirementfortheconcretefloor金属耐磨地坪是在新浇混凝土初凝后开始施工，按顺序进行，因此新浇混凝土的施工质量直接影响着金刚砂耐磨地坪面层的质量。金属耐磨地坪对新浇混凝土的要求为：Startmetallicfloorafterconcreteprimarycongealment,theconcretegroutingqualitywillbedirectlyaffectthequalityofemerywearabilityfloor,sotherequirementfortheconcretegroutingis:1.为防止地坪空鼓，基底表层应清理干净，去除浮浆、油渍；基底需用水湿润。Topreventhollowfloor,cleanoffthefloatslurryandgreasesonthebaselayer,wetthebaselayer.2.基层混凝土标号应不小于C20。TheconcreteclassofthebaselayershallnotbelessthanC20。3.应控制好混凝土的水灰比，金属地坪的混凝土水灰以不大于0.5为宜。Controltheconcretewatercementratio,theratioofconcretefloorshallnotbebiggerthan0.5aswell.4.新浇混凝土选用商品砼时其坍落度应控制在12-14cm之间。Theslumpoftheready-mixedconcreteshallbecontrolledbetween12cmand14cm5.新浇混凝土骨料的含泥量应控制在1%以内，最大骨料粒径控制在3cm以内。Themudrateintheconcreteaggregateshallbecontrolledwithin1%,themaximumdiameterofstonesshallbelessthan3cm.6.新浇混凝土宜用平板振动器或用钢制辊筒捣实，在无法用辊筒压实的部位，可先用木蟹拍实，再用长靠尺刮平找平，新浇混凝土捣实后应及时对其面层水平进行控制，对偏差部位加以调整，新浇混凝土面层平整度应控制在4mm以内。Itisbettertouseflattypevibratororsteelrollerforconcretesurfaceleveling.Usewoodplatetocompacttheconcretewherecannotberolled,levelthesurfacewithlongwoodstrips.Theconcretesurfacelevelerrorshallbecontrolledwithin4mm.7.混凝土面多余的泌水应及时除去，施工时可以用皮管吸去多余泌水，亦可用海绵吸取、转移多余泌水。.Getridoftheredundantwaterontheconcretesurfacebyrubberhoseorsponge2）、金属耐磨地坪施工技术要求Technologyrequirementformetallicfloor去除浮浆Clearoffthefloatslurry新浇筑的地坪混凝土表面浮浆较多，施工时混凝土表面的浮浆必须清理干净，不影响地面的施工质量。当新浇混凝土初凝期后（即上人而不明显下沉为标准），用加装圆盘的机械镘均匀地磨掉混凝土表面的浮浆层即可。Therearelotsoffloatslurrysontheconcretesurfacewhentheconcretegroutingjustfinished,wewillusemachinewithroundtraystocleanoffthefloatgroutafterconcreteprimarycongealment.撒布耐磨材料Broadcastwearabilitymaterial先根据设计要求，确定每平方米耐磨材料的用量，一般2-3mm厚面层，耐磨材料用量为5kg/m2左右。金属矿物骨料分二次撒布，第一次撒布用量为总用量的2/3，第二次为总用量的1/3，即第一次每平方米地面撒布耐磨粉为3.3公斤左右，第二次每平方米撒布用量为1.7左右第一次撒布结束大约间隔一小时，可接着进行第二次的撒布，这样可使材料充分吸收表面未及蒸发的水分。Accordingtothedesignrequirement,confirmthewearabilitymaterialusagequantitypersquaremeter.Thesurfacethicknessnormallyshallbe2~3mm,thematerialusagequantityshallbe5kgperquaremeter.BroadcastBonddexmineralpowdertwotimes,broadcast2/3ofthegeneralquantityatthefirsttime,1/3atthesecondtime.Itissaidthatbroadcastabout3.3kg/m2atfirsttime,andthesecondtimeisabout1.7kg/m2,thetimespacebetweenthefirsttimeandthesecondtimeisonehour.Thematerialwillfullyabsorbtheun-vaporingwaterinthisway.撒布耐磨粉时，一定要均匀，施工过程中应注意按照混凝土浇筑的顺序，先浇的地面先撒粉。撒布时应注意不要撒布到已完工的区域，施工前对已做好的区域应采取临时保护措施，避免造成污染，特别是上、下交叉作业和同一平面分仓作业时更应注意对已完成品的保护。Mustuniformlybroadcastthepowder,becarfortheconcretegroutingsequence,broadcastthepowderonthefinfishedconcretefloorfirstly.Donotbroadcastthepowderintotheun-finishedareaandtaketemporaryprotectionmeasuresforthefinishedareabeforebroadcastingtoavoidpollution.Mustpayattentiontoprotectthefinishedproducts.提浆及表面收光Groutcleaningandsurfacefloating完成撒布后待耐磨材料吸收一定的水分后（一般来说耐磨粉吸收混凝土基层的水份后颜色会变深），用加装圆盘的机械镘按照撒布的顺利进行压磨提浆，施工时至少二次用带镘的机械纵、横交错进行压磨提浆；对于柱子、墙体跟部等临边、临角部位机械不容易压磨，则可直接用手工木蟹进行压磨、提浆。Afterbroadcasting,usemachineswithroundtraystocleanthefloatgroutonthefloor,atleasttwotimes.Theplacethatthemachinecannotworkonsuchascolumns,bottomofthewall,edgesshallbegrindedandcompactedwithwoodplatetocleanthegrout.完成地面提浆施工后，视混凝土的硬化情况，当地坪表面渐无光泽后，即可进行面层的收光施工，收光时至少三次改装机械镘的叶片。机械镘的运转速度和叶片角度的变化应视地坪混凝土的硬化情况作相应的调整。每次收光开始时调节一次叶片的角度，避免损伤地坪。收光是耐磨地坪最终修饰作业，所以施工时一定要选择责任心强、技术水平较好的人员进行作业。Aftergroutcleaning,accordingtotheconcretehardensituation,startfloatingwhenfloorsurfacebecomesdark.Changethelaminasonthemechanicaltrowelatleastthreetimesduringthework.Accordingtothefloorhardensituation,adjustthemachineworkingspeedandlaminasdegree.Thefloatingisthefinalprocedureofthefloorwork,sowemustselectskilledworkerswithstrongresponsibilitytodothiswork.机械作业处理不到的部位则由人工用铁抹子进行压光处理，施工时人工收光应稍早于机械，作业时尽量减少砂眼和收光痕迹的出现，并保持接缝平整。以确保整个地面的施工质量。Theplacehasnobeentreatedbymachineswillbetreatedwithmanualfloating.Themanualworkshallbeearlierthanthemachinework,trytoreducethesmallholesandfloatingmarksandkeepthejointsinlevel.耐磨地坪的养护Curingforthewearabilityfloor耐磨地坪同其它水泥地坪一样，后期养护的好坏直接关系到，地坪的耐磨性能，特别是在气温较高的天气里施工时，更应该加强对地坪的养护。为了确保地坪混凝土和耐磨材料强度的稳定增长，地坪施工完成5-6小时后（冬季施工时养护时间可适当延迟，但最晚不可超过24小时），即可进行养护，耐磨地坪的养护可采用在其表面涂敷养护剂的方法，亦可直接用水或用薄膜覆盖的方法进行养护，但冬季，特别是气温低于零度以下的冰冻天气里，耐磨地坪严禁采用浇水法进行养护，地坪的养护时间一般应不少于7天。Thewearabilityfloorissimilarwiththenormalconcretefloor,thecuringqualitywilldirectlyaffectthewearabilityperformance,weshallstrengththefloorcuringespeciallyinthehightemperaturedaysandinwinter.Toensurethequalityofnormalconcretefloorandwearabilityfloor,startcuring5~6hoursafterfloating(thetimewillbedelayedinthewinter,butnomorethan24hours).Forthewearabilityfloorcuring,wecanusecuringagents,orspraywateronthefloorsurface,orcoverfilmsonthefloor.Butinthewinter,especiallthetemperatureislowerthanzero,spraywaterforcuringisprohibitedandthecuringtimeshallbenolessthan7days.养护期间，地坪表面要防止其他工种施工时油、灰浆、染料、腐蚀性液体等污染，必须经过地坪表面的设备要加设保护设施。在养护期间耐磨地坪表面严禁负重和进行交叉作业。Duringthefloorcuringperiod,topreventpollutionbygrease,mortar,causticityliquidduringconctruction,mustsetprotectionmeasuresonthefloorforequipmentinstallation.Cannotworkonorloadthe
