通过对中日两国混凝土组成材料核素含量的比较分析,提出了混凝土低放射化的必要性,并就低放射性混凝土的评价和组成阐述了自己的观点。建议将混凝土的低放射性问题作为安全性能的评价指标之一,研究制定低放射性混凝土的设计方法,促进混凝土行业整体水平的提高。 Based on the comparative analysis of nuclide content of concrete components in China and Japan, the necessity of low radiation of concrete is put forward and its own viewpoints are expounded on the evaluation and composition of low-level radioactive concrete. It is suggested that the low radioactivity of concrete should be taken as one of the evaluation indexes of safety performance to study and formulate the design method of low-radioactive concrete so as to promote the improvement of the overall level of concrete industry.
