摘　　要：由于自密实混凝土稳定性问题的隐蔽性及其发生原理的复杂性,使其缺少适合的评价方法,这就严重阻碍了自密实混凝土的推广和利用。本试验分析了自密实混凝土稳定性问题的产生机理,综述了现存的自密实混凝土稳定性评价方法,并对各种试验方法进行了比较分析,对其发展趋势进行了展望。The imperceptibility and the complexity of its principle of the stability problem of self-compacting concrete lead to a lack of suitable evaluation method,which hindered the promotion and utilization of self-compacting concrete seriously.A short introduction of the mechanism of the stability of self-compacting concrete was made,meanwhile, some summarizations currently of the experiments which were used to evaluate the stability of self-compacting concrete were recommended.Under above, some contrasts and analysis were also made to through light on the trend of the development.
