Caracterização de blocos cerâmicos estruturais na região da Canastra

Structural masonry is a vernacular construction system that, however, fell into disuse with the development of reinforced concrete structures. This construction method has been applied, albeit empirically, since the early stages of human activities related to construction. Currently, there is a resurgence of vernacular techniques, which benefit from technological advancements, refinements, and established technical standards to govern procedures in the best possible way. In light of this, it is crucial to assess the quality of structural ceramic blocks reaching the end consumer. The objective of this study is to characterize the structural ceramic blocks available in the Canastra region, evaluating their structural performance and physical characteristics. The clay mixture used and ceramic blocks were assessed using a methodology established in national standards, and the results were evaluated against the standard and reference authors. The clay mixture used would benefit from the addition of leaner clays. As for the structural blocks available in the region, they comply with the prescribed standards, except for the loss of mass when exposed to fire.
