Current methods to test concrete, like chemical testing or microscopy, are slow and destructive. Further they will need expert operators and some only test certain parts and can't detect water without separate tests. This invention solves said problems by offering a fast, one-step, non-destructive testing method that sees everything, including water, in one go. It does not need sample prep or damage the material, making testing easier and more accurate.
This invention uses prompt gamma neutron activation analysis (PGAA) to analyze materials, especially concrete, without damaging them. It fires neutrons at the sample, which then emits gamma rays. By measuring those rays, the material's makeup can be identified, including cement, sand, aggregates, and water. It can even detect hydrogen, making it possible to find water content directly. The system works non-destructively and can be automated for real-time quality checks.
