During Soundness testing of Cement by Lechatelier method the Cement mould expands about 20 mm when merged in curing water for 24 hours after mould preparation.In that Cement MgO content is about 3.0%,SO3 is about 2.6% & Blaine is about 360 M2/Kg.Guess the reason & suggest solution.
2537As per X-ray Fluorescence theory, when material particle is irradiated with X-ray the electron of innermost orbital of that element atom is exited and emits outside of the atom as photoelecrons, living behind a hole in innermost orbital . This hole is filled by outer orbital electrons. The question is that finely what happens to that photo electon which is emitted outside of the atom?
