    Effect of intermetallic compounds on the activation of aluminium anodes
    Journal of Alloys and Compounds, 247 (1997) 210-216

    ABSTRACT
    The electrochemical characterization of aluminium anodes containing different intermetallic compounds in 3% sodium chloride and 0.3% sodium sulphate aqueous solutions was carried out by means of d.c. measurements. The case of some Ca-Zn, Ca-In and Al-Mg-Zn intermetallic compounds in the aluminium matrix was examined. SEM and EDAX analyses were used to examine the surface structure of the anodic materials. The relationship between morphological structure and electrochemical results was studied and particular attention was paid to the influence of the intermetallic phases on the activation of aluminium anode materials. Different heat treatments, performed to ensure the dispersion of the fine intermetallic phases, were adopted and the results are briefly discussed.

    3. Activation of aluminium anodes by the presence of intermetallic compounds
    Electrochimica Acta, 42 (1997) 2369-2380

    ABSTRACT
    The electrochemical and corrosion behaviour of Al-Mg-Zn alloys in 3% sodium chloride and 0.3% sodium sulphate aqueous solution was studied, by means of dc and ac measurements at different polarization conditions. SEM and EDAX analysis were employed in order to characterize the surface structure of the above alloys. The relationship between morphological structure and electrochemical results was examined and particular attention paid to the influence of the secondary phase. Different heat treatments, performed to ensure the dispersion of the fine intermetallic phases, were carried out and the results briefly discussed.

    4. Organic coatings for concrete protection: liquid water and water vapour permeabilities
    Progress in Organic Coatings, 30 (1997) 293-297

    ABSTRACT
    This paper reports an investigation of the effectiveness of a range of concrete coatings for reducing liquid water penetration and for allowing water vapour exchange between substrate and the external atmosphere. New methods for liquid water and water vapour permeability evaluation are presented.

    6. Study of the physico-chemical properties of organic coatings for concrete degradation control
    Construction and Building Materials, 11 (1997) 365-371

    ABSTRACT
    The main properties of a protective coating for concrete and reinforced concrete structures are discussed. The importance of evaluating water and water vapour permeability is highlighted. Two new methods for testing water and water vapour permeability of protective coatings are presented. The reliability of these tests is studied. The proposed measurements could be seen as a preliminary screening test that would easily and economically evaluate coating performances.
