摘要
西安荣民金融中心工程结合设计与施工特点,采用高强自密实混凝土浇筑核心筒剪力墙及桁架楼承板。基于原材料选择、配合比设计、施工质量控制等,对高强自密实混凝土性能与实际应用进行研究。研究结果表明,应将现场养护试件抗压强度作为施工参考依据;高强自密实混凝土具有良好的抗氯离子渗透性能;高强自密实混凝土早期收缩试验结果可作为现场施工参考依据。
Based on the project of Xi’an Rongmin Financial Center,high strength self-compacting concrete is adopted to pour core tube shear walls and truss floors bearing plates according to the characteristics of engineering design and construction.Based on the selection of materials,mix proportion design and construction quality control,the performance and practical application of high strength self-compacting concrete are studied.The research results show that the compressive strength of the on-site curing specimen should be used as the reference for construction.High strength self-compacting concrete has good resistance to chloride ion penetration.The early shrinkage test results of high strength self-compacting concrete can be used as reference for site construction.
