Monografia Acesso aberto Avaliação de qualidade dos blocos de concreto da região da Grande Florianópolis(2017) Hanemann, Ricardo Barbosa; Schmitz, RobertoThis work had as main objective to approach the physical and mechanical tests in structural blocks of concrete of some companies located in the region of Florianopolis / SC. With the evaluation of the data obtained, we sought to verify how the quality of the blocks produced by the industries evaluated in relation to the ABNT specifications for the parameters of compressive strength, water absorption, dimensional compliance and visual aspects of the evaluated products are. For the accomplishment of the tests the samples of five companies were first collected to verify the conformities and qualities of the blocks. In all, nine samples of each company were collected, totaling forty-five samples. Of these, six of each company, will be carried out dimensional analyzes, as specified in NBR 6136: 2016 and NBR 12118: 2013. Then the axial compression test will be performed. Three pieces from each lot will be submitted to the water absorption and liquid area test. All data collected will be presented through tables and graphs, so the final results of each test can be interpreted in an easy and dynamic way. The results obtained for the evaluated parameters indicate that only the companies D and E, passed all tests performed while the others were rejected in at least one of the evaluation criteria of the tests applied according to the NBR6136: 2016 standard, that is , these companies are in disagreement with the mandatory specifications for product quality assurance in accordance with NBR 6132: 2016.
