The uniaxial pressure experiment was carried out on the whole-age marine cement-based materials. By analyzing this type of material, there is obvious early strength and late strength decay. The X-ray diffraction experiment was carried out on the sample before the pressure test. After the crushing, the characteristic samples were taken for multi-scale electron microscopy. The microstructure of the material was divided into the strengthening region and the weak region, and the microscopic damage process was summarized.
