Abstract

The aim of this paper is to test the effectiveness of certain methods of consolidation in sandstones of different grades of damage. Three organic silicon compounds in different concentrations were applied by spraying. Treated and untreated samples were examined by SEM in order to observe the products of polymerization. Laboratory tests were performed and a comparison of consolidated and original stone has shown that some physical properties have been improved, particularly the reduction of capillarity suction and water absorption. A crystallization test points out the efficacy of the treatments
