Energy-dispersive X-ray (EDX) analysis is a powerful analytical technique used in conjunction with scanning electron microscopy (SEM) to identify the elemental composition of materials at microscale resolutions. In the context of cement and concrete, EDX analysis is instrumental in determining the distribution of elements and identifying phases within the cement matrix, aggregates, or any inclusions and impurities. This technique is crucial for investigating material failures, optimizing cement formulations, and ensuring the quality and durability of concrete, especially under severe environmental conditions such as corrosive environments, extreme temperatures, or heavy load conditions.
