Characterisation of carbonated Portland cement paste with optical fibre excitation Raman spectroscopy
HighlightsA 514.5nm optical fibre excitation Raman system was successfully established.Calcite/aragonite formed in PC paste was identified by optical fibre Raman system.There is a potential for developing a Raman-based optical fibre sensor system.
AbstractThis study demonstrates the potential of developing a future Raman spectroscopy-based sensor system for monitoring carbonation of concrete structures. A tailored optical fibre Raman system was developed under the classical 45° geometry with a specific optical fibre assembly acting as the laser excitation-path. This system was then employed to characterise the calcium carbonate polymorphs, i.e. calcite and/or aragonite [ʋ1 (CO32−) at 1086cm−1], formed in the carbonated PC paste powder. The finding shows a good potential of optical fibre Raman spectroscopy for monitoring the health condition of concrete structures in the future.
