铁尾矿砂的再生利用技术研究摘要铁尾矿在现代建筑中应用较广,尤其针对我国此类大国而言,库存量较大,而且存在整体上升的趋势。当其数量不断的变大,其自身问题也不断暴露出来。以我国为例,目前而言尾矿的利用效率较低,一旦进入到大规模生产模式,其很多问题便会完全暴露出来,产生对于环境的危害等。很大一部分问题集中在其自身堆放面积较大,将会占据土地资源,甚至会引发一些连锁反应。为了真正的帮助我国实现绿色施工以及可持续发展的目标,铁尾矿砂的利用也应该发生自我转变,就当前的形式而言,其主要便应该进入到重复利用模式中,通过比较合理的综合利用,保证其可以实现最大化的利用途径。此次课题研究便是为了针对此项内容,主要针对的便是土木工程建造领域的应用方法,并且分析其是否可以通过改善生态环境缓解社会压力。在此次课题研究中,通过大量的文献内容分析,并且采取了调研模式,针对国内外的利用现状进行了分析总结,找到了其中存在的突出问题,并且针对此类问题形成了探讨,针对探讨提出了建议。在此次论文研究中,主要的内容便是为了提高我国的铁尾砂矿在土木建造中的再生利用效率,真正的帮助我国当代土木工程建立良好的发展途径。关键词:铁尾矿砂;土木工程;再生利用abstractIrontailingsinthemodernconstructionofawiderange,especiallyforsuchahitinChina,alargeinventory,andthereisanoverallupwardtrend.Whenthenumberofitsgrowing,itsownproblemshavebeenexposed.Inourcountry,forexample,atpresent,thetailingsutilizationefficiencyislow,onceenteredintothelarge-scaleproductionmode,manyproblemswillbecompletelyexposed,resultinginharmtotheenvironmentandsoon.Alargepartoftheproblemfocusedontheirownstackingareaislarger,willoccupylandresources,andevenleadtoanumberofchainreactions.InordertoreallyhelptherealizationofChina'sgreenconstructionandsustainabledevelopment,utilizationofironoretailingsshouldalsoselfchange,intermsofthecurrentform,theyshouldenterintothemainrecyclingmode,throughthecomprehensiveutilizationofreasonable,ensureitstoachievemaximumutilization.Thetopicofthisresearchistoaddressthiscontent,mainlyforthecivilengineeringconstructionfieldofapplicationmethods,andtoanalyzewhetheritcanimprovetheecologicalenvironmenttoeasesocialpressure.Inthispaper,throughtheanalysisofalargenumberofliterature,andadoptedaresearchmodel,basedonthestatusofusingathomeandabroadwereanalyzedandsummarized,findtheprominentproblems,andtosolvethisproblemformthediscussion,putforwardsuggestionsfordiscussion.Inthispaper,themaincontentistoimproveChina'sirontailplaceruseefficiencyincivilregenerationconstruction,reallyhelpourcontemporarycivilengineeringtoestablishagoodwayofdevelopment.Keywords:ironore;civilengineering;recycling1.绪论.............................................................................................................................................41.1研究背景及研究意义........................................................................................................45)尾矿随意排放到江海湖或草原沙漠,导致环境污染;...............................................51.2国内外研究现状................................................................................................................61.2.1国内研究现状........................................................................................................61.2.2国外研究现状........................................................................................................92.铁尾矿砂概述.............................................................................................................................112.1铁尾矿砂..........................................................................................................................112.2我国铁尾矿应用现状分析..............................................................................................142.3铁尾矿应用存在的危害及当前应用存在的问题..........................................................182.1.2铁尾矿的危害......................................................................................................183.铁尾矿砂的土木工程利用可行性探讨.....................................................................................213.铁尾矿砂的土木工程利用可行性探讨.....................................................................................213.1铁尾矿所包含的成分和具体性质分析.....................................................................213.1.1试样分析.........................................................................................................213.1.2对铁尾矿中的化学成分进行研究.................................................................223.1.3铁尾矿中所包含的矿物成分探讨...................................................................223.2探讨铁尾矿稳定性.....................................................................................................233.3铁尾砂矿应用分析..........................................................................................................234.土木工程中铁尾砂矿的再生利用技术.....................................................................................264.1铁尾砂矿混凝土制备......................................................................................................264.1.1铁尾砂矿制备混凝土基础性能简介..................................................................274.1.2制备工艺..............................................................................................................284.2铁尾矿砂免烧砖..............................................................................................................294.2.1免烧砖简介..........................................................................................................294.2.2免烧砖制备方法..................................................................................................304.3铁尾砂矿免烧砖的优势分析..........................................................................................315结论与展望..........................................................................
