自流平水泥的施工方案自流平施工前应该注意的三要素：①湿度：地含水率应小于3%(自流平厂商要求保持施土前地表干燥)。使用CCM水分测试仪。②表面硬度：用锋利的凿子快速交叉切划表面，交叉处不应有裂。使用硬度刻画器。③表面平整度：用2米直尺检验，空隙不应大于2MM。使用平整度测试仪。施工工艺1.检查地面湿度,确认地面干燥；检查地面平整度，确认地面平整；检查地面硬度，地面应无裂缝。2.彻底清扫地面，清除地面各种污物,如油漆,油污及涂料等等。全面打磨地面。3.彻底吸净灰尘。4.将界面剂用泡沫滚筒进行涂布，进行1：1兑水，每平米用约为100-150克。5.界面剂涂布结束后，需等待1-3小时,保持良好通风，使其完全干燥。再进行自流平施工。6.如果是商用自流平水泥（25公斤）一包应倒入盛有6公斤清洁凉水的搅拌桶内，如果是超强自流平（25公斤）一包应倒入盛有6.5公斤清洁凉水的搅拌桶内，用带浆电钻进行搅拌，直至形成流态均匀的混合物。必须确保无结块。然后迅速的将混合物均匀倒入施工区域，用耙子将自流平均布，并用滚筒进行滚拉，将空气释放。注意要合理安排施工人员，确保在15分钟内将混合好的一包自流平水泥施工完。完成2毫米厚度，每包可涂布约8平米。7.约24小时后，自流平水泥干燥完全，1-2天后可进行地板铺设。备注：地面温度低于5度不能进行自流平水泥的施工。以上提供的干燥时间在室温20度，正常条件下适用。此干燥时间会因低温、高湿度而延长。 Self-levelingcementconstructionplanSelf-levelingshouldbenotedthatpriortotheconstructionofthreeelements:①Humidity:Ground-basedmoisturecontentshouldbelessthan3%(self-levelingcompaniesrequiresthemaintenanceoffacilitiesbeforethesurfacesoildrying).TheuseofCCMmoisturetester.②SurfaceHardness:Useasharpchiselquicklydrawcross-cuttingsurface,theintersectionshouldnothaveburst.Theuseofhardnesscharacterizationdevice.③surfaceroughness:Use2mstraightedgeinspection,thegapshouldnotbemorethan2MM.Usingtheflatnesstester.ConstructionTechnology1.Checkthegroundmoisturefromthegrounddry;checktheflatnessofthegroundtoconfirmthegroundleveling;checkthesurfacehardness,surfaceThereshouldbenocracks.2.Athoroughcleaningontheground,removeallkindsofdirtontheground,suchaspaint,oil,andpaintandsoon.Fullypolishedfloor.3.Thetotalnetabsorptionofdust.4.Willsurfactantcoatedfoamrollerstocarryout1:1Duishui,dosageisabout100-150gramspersquaremeter.5.Interfacialagentcoatingaftertheendoftheneedtowaitfor1-3hours,maintaininggoodventilation,sothatitcompletelydry.Toconductself-levelingShiWork.6.Ifitiscommercialself-levelingcement(25kg)shouldbepouredintoabagfilledwith6kgofcleancoldwaterformixingbucketInside,ifitissuper-self-leveling(25kg)apackagecontaining6.5kilogramsshouldbepouredintocleancoldwatermixingbarrel,Carriedoutwiththeelectricdrillwithaslurrystirring,untiltheformationofamixtureofuniformflowpattern.Mustensurethatnon-caking.ThenrapidlywillbeamixtureofEvenlyintotheconstructionarea,withtherakewillbegravityaveragecloth,anduserollerstorollpullingtheairtorelease.NoteshouldbereasonablesecurityRowofconstructionworkerstoensureagoodmixwithin15minutes,apackofself-levelingcementconstructionfinished.Thecompletionof2mmthickness,eachpacketcanbeCoatingofabout8squaremeters.7.About24hourslater,self-levelingcementdrycompletely,:Surfacetemperatureisbelow5degreescannotbeself-levelingcementconstruction.Abovethedryingtimeatroomtemperature20degrees,normalconditionsApply.Thedryingtimewillbeduetolowtemperature,highhumidityandextended.
