Resumo(s)
The monumental quay Cais das Colunas was built in the decades 1770 to 1790, merged in the
reconstruction plan of the city of Lisbon after the great 1755 earthquake. Characterization
studies of mortars from this period are still very few. In 1997 the quay was partially
dismounted and in 2008 was reconstructed. During the reconstruction intervention ancient
mortars, from the core, were sampled in order to study them. This paper presents the
mineralogical, chemical and granulometric characterization and capillarity water absorption
of samples from these mortars. The analytical methodology comprised: the qualitative
mineralogical analysis by powder method of total sample by X-Ray diffraction; the
quantitative chemical analysis of total sample by X-Ray fluorescence; the water absorption by
capillarity coefficient; the determination of hydrochloric acid insoluble residue; and the
granulometric analysis of insoluble residue. This methodology allowed determining the
simplified composition of mortars. It was confirmed the use of local sands and aerial lime
based binder.
