A comparison of the chemistry and mineralogy of currently available NHL2 and NHL5 limes indicate that there are no clear differences except for the amount of 'undefined material', mainly consisting of an amorphous phase. The chemical composition of these different limes is nearly identical. However, the classification of ancient hydraulic limes is mainly based on their chemistry, obtained from the analysis of ancient mortar binders. Moreover, it is shown that the phase composition of these limes evolves with time. This makes their classification uncertain and difficult. 000002922 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002922 653__ $$a 000002922 7112_ $$a2nd Conference and of the Final Workshop of RILEM TC 203-RHM$$cPrague (CZ)$$d2010-09-22 / 2010-09-24$$gHMC2010 000002922 720__ $$aElsen, J.$$iMertens, G.$$iBalen, K.
