With the arrival of the Europeans to America and the evangelizing project, the convents and monasteries arrived. Since most of them were on the outskirts of the cities and the religious lived in them, they needed water storage, using cisterns for this purpose. This research aims to characterize the lime mortar and brick used in the cistern of Santo Domingo Convent, built at the beginning of the 16th century in Hispaniola Island. Two mortar samples and one brick sample were taken to analyze in laboratory using X-Ray Diffraction (XRD), Differential Thermal and Thermogravimetric Analysis (DTA/TG), X-Ray Fluorescence (XRF), and Fourier-Transform Infrared Spectroscopy (FTIR). The research finding indicates that we have two types of mortars, one in which the binder is lime (60%) and calcium silicate hydrate probably formed by a pozzolanic reaction to reduce the porosity and increase the hydraulicity of the mortar. In the other mortar the binder, in addition to lime (15%), has another component that is silicon, iron, aluminum mineral.

摘要

With the arrival of the Europeans to America and the evangelizing project, the convents and monasteries arrived. Since most of them were on the outskirts of the cities and the religious lived in them, they needed water storage, using cisterns for this purpose. This research aims to characterize the lime mortar and brick used in the cistern of Santo Domingo Convent, built at the beginning of the 16th century in Hispaniola Island. Two mortar samples and one brick sample were taken to analyze in laboratory using X-Ray Diffraction (XRD), Differential Thermal and Thermogravimetric Analysis (DTA/TG), X-Ray Fluorescence (XRF), and Fourier-Transform Infrared Spectroscopy (FTIR). The research finding indicates that we have two types of mortars, one in which the binder is lime (60%) and calcium silicate hydrate probably formed by a pozzolanic reaction to reduce the porosity and increase the hydraulicity of the mortar. In the other mortar the binder, in addition to lime (15%), has another component that is silicon, iron, aluminum mineral.
