摘要
从腐蚀机理出发,讨论腐蚀性介质与混凝土组分之间复杂的物理化学作用,分析由于腐蚀作用引起混凝土组分体积膨胀的影响因素,提出了体积膨胀将导致受腐蚀混凝土内部产生膨胀内应力。对膨胀内应力进行定性和定量的研究,并初步给出这种内应力的计算模型,为受腐蚀混凝土力学性能的进一步研究做了基础性工作。
Based on the corrosion mechanism,complex physical and chemical reactions between the corrosive medium and composite of concrete were discussed,influence factors of the volume increase of concrete caused by corrosion were analyzed,expansion internal stress induced by the volume expansion has been put forward.Qualitative and quantitative researches on the internal stress have been carried out,which established the theoretical foundation for the study of mechanical property of the corroded concrete,the computation model of the internal stress was also given.
