Magnetic resonance imaging (MRI) is widely used in the medical field and among one of the greatest inventions in recent years. In MRI images, the bright zone denotes signals that are generated by water in the specimen. However, solid cement-based materials lack water. Therefore, developing a method to achieve optimal saturation for cement-based materials is crucial for MRI scanning.In this study, the immersion, boiling, and vacuum methods were used to achieve saturation for various mortar specimens with w/c ratios of 0.45, 0.55, and 0.65. By comparing MRI images and absorption test results, we found that the vacuum method tends to yield satisfactory saturation levels.
