Carbonation induced corrosion is one of the major durability issues for reinforced concrete structures. To address this issue, it is essential to understand the underlying mechanism of carbonation by detecting the ingress of the CO₂ and carbonation depth quantitatively. This paper demonstrates the potential of Raman spectroscopy, as a powerful technique, to implement quantification analysis of cement paste carbonation. In present work, the correlation between the content of the CO₃²⁻ and the Raman peak intensity was initially established by using several standard specimens premixed with certain amount of CO₃²⁻. The established correlation was then used to investigate the carbonation of the cement paste in a CO₂ diffusion scenario, and the results show a good agreement with that obtained by thermogravimetry measurements. Therefore, the feasibility of the Raman spectroscopy to quantify the carbonation degree of the cement paste can be demonstrated.

碳化引起的腐蚀是钢筋混凝土结构的主要耐久性问题之一。为了解决这个问题，必须通过定量检测 CO ₂的进入和碳化深度来了解碳化的潜在机制。本文展示了拉曼光谱作为一种强大的技术在水泥浆碳化定量分析方面的潜力。在目前的工作中，CO ₃ ^2-含量与拉曼峰强度之间的相关性是通过使用与一定量CO ₃ ^2-预混合的几个标准样品初步建立的。然后使用建立的相关性研究水泥浆体在 CO _{2 中}的碳化扩散场景，结果显示与热重测量获得的结果非常吻合。因此，可以证明拉曼光谱量化水泥浆体碳化程度的可行性。
