The Application of MRI for Scanning Internal Cracks of Cement-Based Material

Abstract:

Regarding the internal structure of cement-based materials, some major concerns the mode of distribution of pores, pore size, and the type in which they are connected. A thorough understanding of the distributive rules of pores and the approaches to break their links will be a considerable contribution to enhancing the durability of cement-based materials. There are several methods to discover the pores of cement-based materials, but cannot show the exact location of pores and the structural links. Magnetic resonance imaging (MRI) has been widely applied to physical examinations. This technique has matured and is now able to obtain information and 3-D images about the organs of recipients without causing damage. The signals from MRI indicate where the hydrogen nucleus is located. However, MRI is seldom used for cement-based materials. In this study, we use H2O as the source of MR image signals in the mortar. Through this experiment, we verify that MRI can be used to analyze the distribution of internal cracks in cement-based material.
