混凝土碳化试验与碳化深度测定方法的对比分析

摘要

For same concrete specimens,the concrete carbonation depths determined by different experimental methods and measurement methods are different.The comparison between experi-mental methods of natural carbonation and accelerated carbonation is provided.The testing prin-ciple and characters of some testing methods,such as phenolphthalein indicator measurement, thermo gravimetry,X-ray diffraction,and infrared spectrometry,are presented and analyzed in this paper.%利用不同的混凝土碳化试验方法和碳化深度测定方法测试得到的混凝土碳化深度存在差异。通过对自然碳化和实验室加速碳化两种碳化试验方法的对比分析，以及酚酞指示剂法、红外光谱法、热分析法和 X射线物相分析法等碳化深度测定方法的对比，分析研究了各混凝土碳化试验方法与碳化深度测定方法的原理和各自的特点，可以为混凝土结构碳化分析的试验方法选择提供参考。
