摘要
混凝土的质量与核电厂结构的安全关系重大,因此,各国对混凝土原材料都有着严格要求并制定了相应的标准。随着我国核电的高速发展,在核电技术引进来和走出去的过程中,标准规范方面的差异是工程技术人员必须面对的重要问题之一。本文对国标和美国标准ASTM关于混凝土原材料的指标进行了较为全面详细的对比,包括水泥、骨料、粉煤灰等主要技术参数。通过对比分析,可以为混凝土工程的设计施工人员提供参考,也可以为核电工程用混凝土原材料的选择和确定提供一定的依据。
In the construction of nuclear power station, the quality of concrete is related to the structural safetysignificantly. As a result, the requirements of raw material of concrete in the regulations published by many countries arevery strict. As the rapid development of nuclear engineering, civil engineers must face the problems related to thedifferences of concrete specifications.The requirements of concrete raw materials are compared comprehensively based onthe GB Code and ASTM regulations, including the comparisons of cement, aggregate, fly ash and so on in order to providesome suggestions to the civil engineers. The result of this paper could also be referenced in determination of concretematerial used in nuclear engineering.
