Abstract

Stress corrosion cracking of untreated Pentelic marble of artificially weathered or treated with pigmented or unpigmented polymer Th. Skoulikidis, P. Vassiliou, K. Tsakona, E. Kritikou Department of Materials Science and Engineering, Faculty of Chemical Engineering, National Technical University of Athens, Athens 157 80, Greece ABSTRACT The mechanical behaviour of pentelic marble under Stress Corrosion Cracking (S.C.C.) conditions was examined by accelerated laboratory tests. The marble specimens were double notched; they were tested (strain stress) untreated or after artificial weathering (exposure in an acidic environment simulating acid rain conditions, or in air + SC^ + humidity, simulating sulfation conditions) or treated with n-semiconductor pigmented or unpigmented polymer. The dispersion of the measured load to failure was high due to the natural unhomogeneity of the marble and consequently of the specimens. These measurements
