I青岛理工大学毕业论文题目:锦里七号工程混凝土原材料质量检测学生姓名:林鹏学生学号:201273089院系名称:土建工程系专业班级:监理124班指导教师:安庆锋2015年6月12日青岛理工大学毕业论文I摘要混凝土的主要材料仍然是以水泥、沙、石子、水为主要原材料,粉煤灰、膨胀剂、减水剂、泵送剂为辅助材料。建筑工程的质量安全,归根结底是材料的品质问题。随着社会的不断发展,任何一种工程都离不开混凝土的运用,混凝土成为了现阶段的重要材料。在现阶段的发展中,建筑混凝土材料在建筑工程的作用越来越大,保证建筑混凝土原材料的质量,提高其可靠性已经引起了社会的广泛关注。混凝土工程的每一道工序都紧密先连,互相影响,对混凝土的最终质量都有很大影响。混凝土原材料的检测是整个混凝土工程里首要的问题,没有好的配合比的混凝土,就不可能有一项好的工程。在实际的工作中常常出现同一配合比,混凝土试块的抗压强度却有所差异究其原因,作为原材料的砂、石、水泥都能影响混凝土的强度。对于原材料的检测,国家有相应的标准规范,试验室必须及时掌握标准的修订情况,同时注意到原材料某个项目可能在不同标准中有不同的检验方法,如GB/T1596—2012用于水泥和混凝土中的粉煤灰,GB/T18736—2010《高强高性能混凝土用矿物外加剂》两个标准都有粉煤灰需水量比试验方法,GB/T1596—2012的方法较为烦琐。有时使用者需对原材料进行快速检测以控制生产,或比较几个产品间优劣,需要有可行的检验方法,采取的方法未必是国家标准。通过结合某建筑工程实例,提出了工程中对混凝土施工过程中进行原材料以及混凝土配合比检测与主要内容,从检测结果表明施工质量的可行性,来指导施工。关键词:混凝土;原材料;质量检测青岛理工大学毕业论文IIAbstractThemainmaterialofconcreteisstillinthecement,sandandgravel,waterasthemainrawmaterial,flyashandexpansiveagent,waterreducingagent,pumpingagentasauxiliarymaterials.Thequalityofconstructionengineeringsafety,inthefinalanalysisisthequalityofthematerialproblem.Withthecontinuousdevelopmentofsociety,anykindofprojectisinseparablefromtheuseofconcrete,concretehasbecometheimportantmaterialatthisstage.Atthisstageofdevelopment,theconstructionofconcretematerialsintheroleoftheconstructionprojectismoreandmorebig,ensuretheconstructionqualityoftherawmaterialsfortheconcrete,improveitsreliabilityhascausedthewideattentionofthesociety.Everyprocessofconcreteengineeringcloselyevenfirst,influenceeachother,hasagreatinfluenceonthefinalqualityofconcreteis.Concreterawmaterialstestingistheprimaryproblemsintheconcreteengineering,withoutagoodproportionofconcrete,isimpossibletohaveagoodproject.Oftenappearintheactualworkthesamemixtureratio,thecompressstrengthofconcreteblockhasdifferentinvestigateitsreason,astherawmaterialsofsand,stone,cementcanaffectthestrengthoftheconcrete.Testingforrawmaterials,thestatehasacorrespondingstandardspecification,laboratorymusttimelygraspthestandardrevisionofthesituation,andnoticedthataprojectofrawmaterialsmayhavedifferenttestmethodsindifferentstandards,suchasGB/T1596-2005workersincementandconcreteinthepulverizedcoalpower0,GB/T18736-2002highstrengthhighperformanceconcretewithmineraladmixturetwostandardsareflyashwaterrequirementratiotestmethod,methodofGB/T1596-2005ismorecumbersome.Sometimesusersneedtofastdetectiontocontroltheproductionofrawmaterials,orcomparingadvantagesanddisadvantagesbetweenafewproducts,needtohaveafeasibleinspectionmethod,approachisnotnecessarilytothenationalstandard.Bycombiningwithaninstanceofaconstructionproject,theconstructionprocessofconcreteengineeringarepresentedforrawmaterialsandthemixtureratioof青岛理工大学毕业论文IIIconcretetestandthemaincontent,fromthetestresultsshowthatthefeasibilityoftheconstructionquality,toguidetheconstruction.Keywords:concrete;Therawmaterials;qualityinspection青岛理工大学毕业论文I目录摘要................................................................IAbstract........................................................................................................................II第一章绪论................................................................................................................11.1研究的背景......................................................................................................11.2研究的目的及意义..........................................................................................11.3研究的内容及方法..........................................................................................21.4混凝土原材料的现状及发展..........................................................................2第二章锦里七号工程混凝土原材料质量检测........................................................42.1工程概况..........................................................................................................42.2混凝土原材料的成分......................................................................................52.3混凝土原材料成分的性能检测......................................................................62.31搅拌用水检测........................................................................................62.32水泥检测...............................................................................................72.33粉煤灰的检测......................................................................................102.34碎石骨料检测......................................................................................122.35外加剂检测..........................................................................................17第三章混凝土配合比计算及相关性能的检测........................................................213.1混凝土配合比................................................................................................213.11确定适配强度......................................................................................213.12确定水灰比..........................................................................................213.13用水量的选定......................................................................................223.14砂率的选定..........................................................................................233.15配合比的试配、调整与确定...............
