Estudio de la alteración de los biocidas con los materiales pétreos del yacimiento del Cerro de la Plaza Armas de Puente Tablas (Jaén)

Abstract

The archaeological site of Puente Tablas presents, as main problem related to biodeterioration, superior plants, that grow over the excavated structures, so that three biocide treatments have been studied. In this work the possible effect of these treatments on the stony materials most abundant (red and grey limestones) on the houses and wall has been determined. The tests carried out before and after the application on the stone samples have been: capillarity water absorption, cromatic changes measurement, SEM observation and accelerated weathering test. The effects of the biocide treatments are inapreciable, except a slight change of colour due to one of them.
