Chronopoulos National Technical University of Athens, Laboratory of Electrochemistry & Reinforced Concrete, Zografou Campus, 15773, Athens, Greece ABSTRACT A series of mortars and grouts commonly used in structural restoration of old masonry as well as in building with new masonry (and especially reinforced one) were tested under in-lab and in-situ conditions at NTU of Athens, within the framework of an extended BRITE-EURAM research programm, financed by EU.
