What kinda differences would be there if I go for SEM testing of (1) cement paste i.e., cement plus water (2) mortar i.e., cement + water + sand and (3) concrete i.e., cement + water + sand + gravels? Also let me know which case would be more appropriate in order to discuss the phase characterization of the products formed therein such as the main hydration products e., CSH (calcium silicate hydrate) and CH (calcium hydroxide).
One more can I assess the structures of either of these two hydration products in which case, I have to first dehydrate my samples prior to going for SEM testing (during the sample preparation stage)? So if dehydrated, there would be neither CSH nor CH in the prepared samples for SEM.
