| Abstract: | As a new type of porous material, ceramsite-based foamed concrete composite (CFC) has been widely used in protection and other industries in recent years. To investigate the dynamic mechanical behavior, damage characteristics and energy absorption characteristics of CFC under impact loading, impact tests with strain rate of 115 s−1∼200 s−1 were carried out on CFC with different density and ceramsite content using separated Hopkinson pressure rod device (SHPB), and compared with a density grade of foam concrete (FC). A comprehensive comparative analysis was performed on the dynamic failure processes, damage characteristics, stress–strain responses, peak stresses, energy evolution, and fracture morphologies of the two materials. In addition, synchronized high speed imaging, scanning electron microscopy (SEM), and CT scanning were employed to further characterize the dynamic impact failure process and the microstructural features of CFC. The experimental results indicate that the incorporation of ceramsite lightweight aggregates into foamed concrete can increase the peak stress by 151% and the energy absorption density by 211%. Among all specimens, CFC800-50 exhibits the highest energy absorption density, reaching up to 1.60 MJ/m3. In practical engineering applications, CFC can achieve a balance between compressive load bearing capacity and energy absorption performance, making it well suited for protective structures dominated by explosion and impact loads.
