Salt-fog experiments on consolidant and water-repellent treated dimension stones

N. Leal, J. Simão, C. Gartmann & Z. Silva
Carbonate (three limestones) and silicate rocks (one nepheline syenite and one granite) wereselected in order to study the effects produced by marine environments, after surface treatmentshad been applied in their polished surfaces. Four samples of each type were prepared,involving the use of a consolidant and/or of a water-repellent. Samples were subjected to sixsalt-fog experiment series, according to an adaptation of European Standard EN 14147 Eachseries comprehends 15 cycles with a sequence of 4 hours of...
