摘要: In this study, binder-aggregate interfacial transition zone (ITZ) of some hydraulic lime based mortars is analyzed in order to determine the way which their morphological and compositional structure related strength durability development. To achieve determination, using a mortar as starting point, several mixes were prepared with metakaolin (MK), sepiolite, Portland cement additions. Lime ITZ was compared mortars, obtained both from natural (NHL) mentioned artificial mixes. Scanning electron microscopy (SEM) energy dispersion X-ray analysis (EDX) microanalysis techniques combination stress tests carried out. Results showed most radical behavior MK addition rather than addition, even at 1:1 ratio. Continual zones together higher strengths correspond smaller aluminate phases hydrogarnets. Thus, small ...
