Avaliação da qualidade de blocos cerâmicos comercializados em Jataí-Go, conforme a NBR 15270 – 1/2017

Abstract

The ceramic blocks is one of the most manufactured products using red ceramics in Brazil. Their main function is to place environments. The quality of these blocks is directly linked to the products that compose then and the manufacturing. Even with the emergence of several new technologies, ceramic blocks, when it comes to placement still the most used product in Brazil. Therefore, there is still no specific body for monitoring and checking whether production complies with the regulatory requirements regulated in the NBR. 15270:2017, this work aims to verify the production of ceramic blocks sold in the city of Jataí located in the interior of Goiás. A study was carried out in order to know the quality of the blocks sold in this city and tested based on the guidelines of NBR 15270:2017, with this presented the data from the conformity assessment of ceramic blocks for masonry installation of minimum criteria. The checks of the test specimens were carried out in a technical laboratory at IFG in Jataí, using equipment recommended by the standard, obtaining that the results of geometric, physical, and mechanical tests indicated that suppliers have a very large variation in their production and a very high failure rate in tests carried out. Through a compressive strength test, it was seen that very few blocks resist what is indicated by the 1.5 MPa standard. Furthermore, many cracking and deformation defects were found in samples from all ceramic industries, which affect the performance of the pieces. Attention from users and sellers is necessary so that industries comply with manufacturing quality criteria.
