Application of Micro-Structure Testing in the Analysis of the Cause of Concrete Cracks

Abstract:

Scanning electron microscope, differential thermal analysis, thermo-gravimetric analysis, fluorescent analysis and X-ray CT et.al. have become usual means used in the research of concrete material science. This paper proposed a new method to evaluate the causes of cracking of in-situ concrete based on the investigation by using these comprehensive technologies for analysis of micro-structure. The proposed new method is more reliable and objective than the traditional method which is mainly based on experience and chemical analysis. A case investigation using the new method to explore the causes of cracking in a real project was introduced.
