Recent Advances in X-ray Computed Tomography for Alkali-Activated Materials: A Review

Alkali-activated materials (AAMs) have been extensively studied due to their high performance and low carbon emissions. However, the long-term durability of AAMs remains a major concern, which is closely related microstructures pore networks. X-ray computed tomography (CT) has emerged as powerful non-destructive technique for threedimensional microstructural analysis in field civil engineering. While CT widely used investigate cement-based materials, its application still limited. In this review, we provide comprehensive summary background information applications AAM research, focusing on structure analysis, phase identification, degradation fiber reinforcement, temporal evolution simulations. Furthermore, current challenges future perspectives are also discussed.
