Verificação da qualidade dos blocos vazados de concreto simples para alvenaria sem função estrutural, produzidos na região metropolitana de Goiânia.

Abstract

In Civil Construction, different materials can be used for the same purpose, such as partition blocks, which may be made of ceramic or concrete. Several factors determine which type should be used according to the needs of the construction. For concrete blocks to be suitable for use, they must comply with pre-established standards, verifying whether they meet all the necessary requirements for application. The standardNBR 6136 (2016) Hollow concrete blocks for masonry specifies the tests to be carried out for the determination and quality analysis of the studied material. This study characterized non-structural concrete blocks from three different factories located in the metropolitan region of Goiânia: two small-scale manufacturers located in the regions of Goiânia-GO and Nerópolis, and one large-scale manufacturer located in the region of Senador Canedo-GO. The results showed that only the large- scale company met all the requirements established by the standard. The adopted methodology consisted of conducting a literature review on the proposed topic, presenting a mapping and characterization of the concrete block production sector in Goiânia and the metropolitan area, and performing the tests on the concrete blocks according to the NBR 6136 (2016) standard. The results were analyzed and compared with the requirements specified in the standard, showing the current quality of hollow concrete blocks. This study is necessary considering the increasing use of concrete blocks in civil construction, making it important to understand the quality of the products supplied to the market.
