本文指出了《C80混凝土离心试件的尺寸效应研究》一文所建立的混凝土高心试件尺寸效应力学模型有误。讨论了混凝土高心试件强度低于立方体试件强度是因为中国和日本所采用的混凝土抗压强度标准试件不同所致．提出了以提高立方体试件强度来保证离心试件强度达到C80级的办法。
This paper points out that the size effect mechanical model of the concrete high-center test piece established in the article “Study on the Size Effect of C80 Concrete Centrifugal Specimen” is incorrect. It is discussed that the strength of concrete high-core specimens is lower than that of cube specimens due to the different standard compressive strength specimens used in China and Japan. A method was proposed to increase the strength of the cube specimen to ensure that the centrifugal specimen strength reached C80 level.
