Laboratory studies for stone conservation at the Cathedral of Murcia

Abstract

The results of a series of laboratory tests, carried out on the bioclastic limestone used in the construction of the Murcia cathedral, are presented in this paper in order to evaluate the efficiency of certain treatment products, that eventually could be applied to that stone for improving their state of conservation. Additionally, the behaviour under accelerated ageing tests of non treated samples and the treated ones with the different products employed -ethyl silicate, oligomeric polisiloxane and poliurethane-, is compared.
