However, there is a notable construction project that uses structural ceramic blocks: the "Residencial Liberdade," which is the focus of this study. The objective of this work is to evaluate the application of structural masonry with ceramic blocks and a hydrophobic agent in a low-income housing complex, aiming to reduce time and costs. Quantitative and comparative surveys were conducted based on budget spreadsheets and unit compositions of two projects: the original one, with structural ceramic blocks and hydrophobic agent, and the conventional one, with nonstructural masonry, reinforced concrete structure, plaster, and paint. According to the responsible company, the original project is economically more viable, with a cost savings of 38,81% and an increase in expenses of only 0,61% compared to the conventional project. Considering the property's maintenance, an additional economic analysis was conducted to assess whether the hydrophobic coating actually has lower costs. The results showed that the application of the hydrophobic agent requires a significant investment, both in overall terms and individually.Acesso AbertoBloco cerâmico estruturalhidrofuganteviabilidade técnicaviabilidade econômicaStructural ceramic blockhydrofuganttechnical viabilityeconomic viabilityCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVIL::MATERIAIS E COMPONENTES DE CONSTRUCAOTrabalho de Curso - Graduação - Monografia
