Thijssen, A. Wiktor, V. Jonkers, H.M. Schlangen, H.E.J.G. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2015-06-17 Abstract Ordinary Portland cement (OPC) mortar specimens submerged in sea-water were analysed through environmental scanning electron microscopy (ESEM) in back scattered electron (BSE) mode and nano-scratching. Results from both sets of analysis show the presence of distinct phases associated with aragonite, brucite and cement paste. Phases associated with porosity and aggregates were also distinguishable through the BSE analysis and less defined in the nano-scratch data. This study indicates the powerful nature of coupling BSE image analysis with nano-scratching to obtain information on the quality of concrete. Work is underway to improve the method in order to apply it for better understand on the micro-physicochemical properties of marine exposed concrete.
