测试技术和分析方法对于材料性能评价发挥着重要作用。在建筑领域,集料的品质常常为人们所忽视。本文全面剖析了核壳混凝土用岩石集料的性能要求,通过岩相、光谱、物理、化学等多种测试技术手段对岩石集料进行了系统检验和综合评价,为重点工程混凝土集料选择和性能测评提供了重要的参考依据。同时系统阐述了集料的多种测试技术手段及评价方法,特别是对于集料碱活性测试的国内外标准进行了比较分析,对于开展核工程用混凝土集料的综合测评和标准研究提供了详细思路。
Testing techniques and analytical methods play an important role in the evaluation of material properties. In the field of construction, aggregate quality is often overlooked. In this paper, the performance requirements of rock aggregates for core-shell concrete are comprehensively analyzed. The rock aggregates are systematically inspected and comprehensively evaluated through various testing techniques such as lithofacies, spectroscopy, physics and chemistry. Performance evaluation provides an important reference. At the same time, the methods and evaluation methods of aggregate testing technology are systematically described, especially the comparative analysis of domestic and foreign standards for aggregate alkali activity testing, which provides detailed information on the comprehensive evaluation and standard research of concrete aggregate for nuclear engineering Ideas.
