采用X射线衍射、扫描电子显微镜、X射线光电子能谱、傅里叶变换红外光谱和激光拉曼光谱等测试技术对英国某桥墩腐蚀试样的微观结构进行了分析，发现试样中存在大量的碳硫硅钙石晶体，证明硫酸盐侵蚀导致碳硫硅钙石的形成，并对碳硫硅钙石的形成机理进行了探讨。
X-ray diffraction,scanning electron microscopy,X-ray photoelectron spectroscopy analysis,Fourier transform infrared spectrometry,and laser Raman spectrometry testing techniques were used to analysis the microscopic structure of corrosion from one pier base in England.There are massive thaumasite crystal in the sample.It was proven that the thaumasite formation due to sulfate attack had occurred obviously.The mechanism of thaumasite formation was also investigated.
