Identificação do tipo de lavra da argila para produção de tijolo que abastece o município de Juruti com caracterização mecânica conforme norma técnica dos tijolos de seis furos

Abstract

This work was carried out in the municipality of Juruti/PA, with the objective of identifying the type of mining practiced in the exploitation of clay, specifically red ceramic, raw material used in the manufacture of ceramic bricks and the carrying out of tests to verify the quality of the bricks following the determinations of NBR 15.270/2017. In order to achieve the two proposed objectives, the methodological procedures were developed in 05 stages that included visits to construction material stores, technical visits to the potteries in the municipality of Juruti and the community of Vila Socorro - Santarém/PA, visits to the clay mining processes , sample collection, visual, geometric, physical and compression tests and finally the analysis of results obtained in the field and in laboratory tests. It has been identified that the exploitation of clay occurs by open pit mining of the wet type, through the mining of Placers, by the dredging mechanism by floating navigation, the mining takes place in the bed of the Amazon River. The tested ceramic bricks were approved in terms of their geometry, there was disapproval of some batches in terms of visual and physical aspects concerning the moisture absorption index.
