摘要: 混凝土脆性影响强度尺寸效应，因此，脆性与强度之间存在内在联系。然而，脆性对不同强度尺寸效应的影响并不相同。通过对高强与超高强混凝土抗压强度的试验研究，探讨脆性影响抗压强度的规律。试验结果表明，脆性不一定直接影响混凝土的抗压强度，却可能由于其实际改变了混凝土所处的约束条件而发生作用。

Abstract: The size effect of concrete strength is influenced by its brittleness.Therefore,there is an inherent relation between them.However,the impact of the brittleness varies from different strength.With the experimental study on the compressive strength of high and super-high concrete,it is explored the law of the correlation between brittleness and compressive strength.The results show that compressive strength of concrete is not sure to be affected by brittleness directly,but it will be done due to the actual change in the concrete binding conditions.
