Estudo das argamassas antigas: o caso da Igreja de Nossa Senhora do Amparo dos Homens Pardos, em São Cristóvão Sergipe

Abstract

This course conclusion work has as main discussion the study of old mortars through the perspective of restoration technology as a means of reading and intervention in the heritage. Therefore, the mortar covering the Church of Nossa Senhora do Amparo dos Homens Pardos, located in the municipality of São Cristóvão in Sergipe, becomes an object of study, which needs an investigation of its coating mortar due to the current pathologies that it afflicts it, consequently affects its physical state, being one of the main harmful agents the displacement of water by the mortar body. It is at this point that historical investigations point to the use of ceramic powder as an additive in the manufacture of lime-based mortar for the inhibition of capillary vessels, the main means of transporting water on parental surfaces, thus, the practice of restoration will enter as a methodology in the investigation through laboratory and investigative analysis, which leads to the understanding that the intervention goes beyond the simple act of acting, but in the total knowledge of the object, its history, composition, physical behavior ... that is , know as much as possible the material worked to ensure a better and effective intervention. In view of this, the research focuses on understanding the coating mortars of the Church of Nossa Senhora do Amparo dos Homens Pardos, as well as proposing a trace added with ceramic powder from the analysis of the trace characterization of the existing coating mortars and subjecting these proposals to testing. of plasticity, liquidity and resistance, as a way to study the interference of the additive of ceramic powder in the improvement of this material
