New mineralogical techniques contribute to prevent national heritage damage

tal rock pores, almost all with little success.

thesiss research line and the above mentioned papers have followed the recent techniques that intend to use additives to modify the crystallization process and prevent or reduce the damage produced in the rock. Up to now, most of the works in this field have assessed the efficiency of these treatments in slightly soluble salts, such as calcium and barium sulphates. The thesis has proved the effectiveness of this type of treatment in highly soluble salts, such as sodium and magnesium sulphates, as well as sodium nitrate, which can usually be found in historic buildings.

Applied science

The research work has been applied to the case of the effects of these treatments in the rock extracted in Santa Pudias quarries (Esczar,-Granada), used in the construction of Renaissance buildings in Granada such as the Monastery of San Jernimo, the Cathedral or the Royal Chapel. These buildings show strong alteration phenomenon due to crystallization in sodium sulphate, magnesium and sodium nitrate.

The work has conducted to the carrying out of salt crystallization tests in laboratory, which simulate alteration processes due to salt crystallization in the bases on historic buildings walls. Later says Ruiz Agudo-, we prepared a method for the implementation of the treatment developed in practical cases of ornamental stone materials conservation. Finally, in a last phase of development of the research project, we applied such treatment in pilot areas on the Monastery of San Jernimo (Granada), where there had been important problems due to salt crystallization.

The final result of the research work proposes the application of low-cost additives, which have proved to be very effective in the fight against the problems of ornamental porous materials. On the other hand, the research work involves a methodology to deal with the study of damage caused by salts and the selection of the most a
