Estudo das argamassas históricas: o caso do Sobrado do Balcão Corrido, em São Cristóvão Sergipe

Abstract

This final course project discusses the study of traditional mortars from the perspective of restoration technology, as a means of understanding and interveningin built heritage. The study focuses on the rendering mortars of the Sobrado do Balcão Corrido, located in São Cristóvão (SE), a building that presents pathologies mainly associated with humidity, compromising its state of conservation. The research is based on the use of ceramic powder as an additive in lime-basedmortars, aiming to reduce capillarity and improve the material's performance. Methodologically, a literature review, field survey, damage map creation, sample collection, and laboratory analyses were carried out, including mix design, granulometric analysis, soluble salt tests, moisture evaluation, and visual observations. Based on this data, a mix design with ceramic powder was developed and evaluated through comparative tests. The results indicated improvements in resistance and moisture control, highlighting the material's potential as a compatible and sustainable alternative for interventions in historical buildings.
