“…quartz, feldspar), and decreases with increasing amounts of 'weak/soft minerals' (e.g. clay, mica) and porosity (Lindqvist et al, 2007;Vernik et al, 1993). Therefore, we plotted the peak strength of experiments performed under the same conditions (i.e.…”

“…The results of the solubilization could also be justified by the fact that the ion Ca +2 has a much smaller size than the ion SO −2 4 , since authors as Lindqvist et al (2007) and Bawendi (2005) affirm that small ions are more solvent than big ones. An ion of small ionic radius may have a bigger hydrodynamic radius, making possible the drag of many molecules of solvent through the solution.…”

This study investigates the displacement of SO −2 4 and Ca +2 ions in a red-clay ceramic, simulating the process of efflorescence. Ceramic bodies were molded (70 × 27 × 9 mm 3 ) by vacuum extrusion formulated with different contents of CaSO 4 · 2H 2 O (0, 2, 4, 8, and 16% in weight) and burnt at different temperatures (800, 850, 900, and 950 • C) for 12 h. Ceramic bodies were characterized in terms of water absorption, apparent porosity, and pore size distribution. Efflorescence was evaluated according to the norms of ASTM C67/2003 and by testing the solubilization of SO −2 4 and Ca +2 ions after 1 h with the ceramic bodies immersed in hot water as well as after 7, 14, and 28 consecutive days with the ceramic bodies immersed in cold water. In the quantification of efflorescence, a new image analysis methodology was developed by using the graphic software Image Tools 3.0. The results allowed in establishing a relationship between the efflorescence of the investigated ions, physical properties (water absorption and apparent porosity), pore size distribution, and solubilization.
