生态混凝土护坡的构建技术及生态效应评价

东南大学学士学位论文I生态混凝土护坡的构建技术及生态效应评价摘要人类进行边坡防护已有很长的历史，但在防护与绿化美化两方面一直没有统一，与传统防护材料相比，生态混凝土既有较高的强度能有效地进行边坡防护、加强边坡的稳定性，提高防护年限，又具有很大的孔隙率便于植物在其中生长，具有改善环境的功能，是一种被广泛认可的生态修复材料，因此，开展生态混凝土的研究具有重要意义。本文主要针对具有生态环保功能的生态混凝土的配合比设计、强度、干湿交替作用下的耐久性、护坡构建和综合生态效应等方面进行了探讨和研究。在基本性能方面，本论文研究了生态混凝土在掺加矿物掺合料时，其强度随着掺合料掺量的变化规律。除此以外，还研究了掺加矿渣的生态混凝土处在干湿交替作用下的耐久性特点，进行了生态混凝土抗干湿交替性能的试验。在护坡构建中，还研究了植物必要的生长环境、生态护坡植物的选择以及生态护坡基质的选择。此外，本文最后研究了不同粗骨料的生态混凝土水质净化性能和污水处理的标准。关键词：生态混凝土，干湿交替，生态护坡，强度，水质净化东南大学学士学位论文IIslopeprotectiontechnologybyecotypeporousconcreteandecologicaleffectsevaluationAbstractThesideslopedefencehasbeenacontinuouscareerforhumanbeings.However,aperfectjunctionhasneverbeenfoundbetweenthesideslopedefenceandvirescence.Comparedwiththetraditionaldefencematerials,ecotypeporousconcretecannotonlyattainahigherstrengthtoefectivelydefendthesideslopeandreinforceitsstabilityinalongerdefenseperiod,butalsogetahighervoidratiotomakeitpossibleforplantstogrowbetterinit.Itreallyfunctionsinimprovingtheenvironmentandhasbeencommonlyconsideredasanecologicalconcrete.Therefore,todoresearchesonecotypeporousconcreteisasignificanttask.Themixproportions,strength,wet-drycircle,buildingthesideslopedefenceandEco-environmentalsecurityofecotypeporousconcretehavebeenstudiedabundantlyinthepaper.Whilethechangeofcompressivestrengthwithsilicafumes,flyashandslagalsohavebeenstudied.Besides,thewet-drycycleresistancepropertyofecotypeporousconcretehasalsobeenstudied.Constructionoftheberm,amajorstudyofthenecessarygrowthenvironment,ecologyslopeofthechoiceofslopeprotectionandecologicalmatrixchoice.Inthelastchapter,themaintestiswaterpurificationandsewagetreatmentstandards.Keywords：ecotypeporousconcrete；wet-drycycle；ecotypesideslopedefence;strength；water-purification东南大学学士学位论文III目录摘要..............................................................................................................................................IAbstract............................................................................................................................................II第一章绪论.................................................................................................................................11.1研究背景............................................................................................................................11.2国内外研究现状................................................................................................................21.3论文研究目的和内容........................................................................................................3第二章原材料、试验方法及配合比设计.................................................................................42.1试验原材料及其基本性能................................................................................................42.1.1水泥.........................................................................................................................42.1.2粗集料.....................................................................................................................42.1.3外加剂.....................................................................................................................42.1.4粉煤灰.....................................................................................................................42.1.5硅灰.........................................................................................................................42.1.6矿渣.........................................................................................................................52.1.7拌和水.....................................................................................................................52.2生态混凝土配合比设计方法研究....................................................................................52.2.1配合比设计简介.....................................................................................................52.2.2配合比设计.............................................................................................................52.2.3配合比设计结果.....................................................................................................72.3生态混凝土的成型工艺及养护........................................................................................82.3.1生态混凝土搅拌过程.............................................................................................82.3.2生态混凝土成型工艺.............................................................................................82.3.3生态混凝土的养护过程.........................................................................................92.3.4试件的尺寸.............................................................................................................92.4生态混凝土试验方案设计.................................................................................................9第三章生态混凝土的基本性能实验.......................................................................................113.1生态混凝土的抗压强度试验..........................................................................................113.1.1强度测试时表面处理方法......................................
