《河南水利与南水北调》2022年第12期试验与研究珠三角水资源配置工程自密实混凝土试验研究熊飞（湖北正平水利水电工程质量检测有限公司珠海分公司,广东珠海519000）摘要：随着科学技术的不断发展，建筑工程建设质量要求的不断提高，对混凝土质地提出了更高的要求，而高质量、高水平的自密实混凝土由于其优异的施工性能在各类型的结构工程中得到了广泛的使用。但自密实混凝土在实际应用前还需要得到充分的实验、论证和检测后方可实施，自密实混凝土工作性能对原材料的波动较为敏感，文章根据珠江三角洲水资源配置工程以自密实混凝土为研究对象，对其配合比设计方法、各类性能及实验、掺合料对混凝土性能影响等进行深入分析，实验表明：高强自密实混凝土应用于珠江三角洲水资源配置工程取得了良好的施工效果。关键词：自密实混凝土；配合比；工作性能；力学性能中图分类号：TU528.5文献标识码：A文章编号：1673-8853（2022）12-0073-03ExperimentalStudyonSelf-compactingConcreteofWaterResourcesAllocationProjectinPearlRiverDeltaXIONGFei（ZhuhaiBranchofHubeiZhengpingWaterConservancyandHydropowerEngineeringQualityInspectionCO.LTD.,Zhuhai519000,China）Abstract：Withthecontinuousdevelopmentofscienceandtechnology,thecontinuousimprovementofconstructionqualityrequirements,thequalityofconcreteisputforwardhigherrequirements.Self-compactingconcreteofhigh-qualityandhigh-levelhasbeenwidelyusedinvarioustypesofstructuralengineeringbecauseofitsexcellentconstructionperformance.However,self-compactingconcreteneedstobesufficienttested,demonstratedanddetectedbeforepracticalapplication.Theworkingperformanceofself-compactingconcreteissensitivetothefluctuationofrawmaterials.Takingself-compactingconcreteinthePearlRiverDeltawaterresourcesallocationprojectastheresearchobject,anin-depthanalysisofitsmixproportiondesignmethod,variouspropertiesandexperiments,aswellastheinfluenceofadmixturesonconcreteperformancearemadeinthispaper.Theexperimentshowsthattheapplicationofhigh-strengthself-compactingconcreteinthewaterresourcesallocationprojectinthePearlRiverDeltahasachievedgoodconstructionresults.Keywords：self-compactingconcrete;mixproportion;workingperformance;mechanica...
