永安一中教学楼二期工程承台大体积混凝土施工质量控制［摘要］现代建筑屮时常涉及到大体积浞凝土施工，如高层楼房基础、大型设备基础、水利大坝等。它主要的特点就是体积大，一般实体最小尺寸大于或等于lm。它的表面系数比较小，水泥水化热释放比较集中，内部温升比较快。混凝土内外温差较大时，会使混凝土产生温度裂缝，影响结构安全和正常使用。所以必须根据工程实际情况从根本上分析它，来保证施工的质量。木文通过永安一屮教学楼二期工程承台大体积混凝土施工对承台大体积混凝土质量控制技术措施进行详细的闹述。［关键字］大体积砼承台裂缝TheconstructionqualitycontrolofmassconcreteontheteachingbulidingphaseIIslabofYonganFirstHighSchool[Abstract]Modernbuildingsofteninvolvedinmassconcreteconstruction，suchashigh-risebuildingsbasedonthebasisoflargeequipment,irrigationdams.Itsmainfeatureisthelargevolume,generallygreaterthanorequaltotheminimumsizeoftheentity1m.Itssurfacecoefficientisrelativelysmall，relativelyconcentratedcementhydrationheatrelease,theinternaltemperaturefaster.Concretetemperaturedifferenceislarge,thetemperaturewillproduceconcretecracksaffectthestructuralsafetyandproperuse.Soitmustbeanalyzedaccordingtotheactualsituationoftheprojectfundamentally,toensurethequalityofconstruction.Inthispaper,YonganoneteachingbuildingtwoprojectsforMassConcreteMassConcreteConstructionQualityControlmeasuresindetail.[Keyword]MassconcreteCushioncapCrack目录:U呈褪..................................................................................................................1一、施工总体部署方案............................................................................................2（-）工艺流程......................................................................................................2（二）.....................................................................................................施工技术方案的确定2（三）.........................................................................................................砼浇筑的质量标准3二、施工准备工作..................................................................................................4（~）材料选择.....................................................................................................4（二）................................................................................................................混凝土配合比5（三）..........................................................................................提前做好浇筑前的准备工作5三、基础承台混凝土热工计算...................................................................................8四、大体积混凝十施工..........................................................................................10（-）施工段的划分..............................................................................................10（二）....................................................................................................................混凝土浇筑10（三）..............................................................................................混凝土的测温监控与养护n五、主要管理措施.................................................................................................12触'语...................................................................................................................13雜语-........................................................................................
