Evaluation of the Industrial Raw Material Used for Ceramic Production in São José de Ubá, State of Rio de Janeiro, Brazil

Abstract:

The northern region of the state of Rio de Janeiro, Brazil, has a significant participation in the country ceramic production for civil construction owing to the abundance of raw materials, mainly kaolinitic clays. Each municipality in that region has ceramic industries using raw materials mined from its own deposits. Products such as bricks and tiles may lack the required quality due to the limited know-how on the applied raw material. The present work conducted a technological evaluation of the clayey raw material used in the municipality of São José de Ubá including its potential for ceramic processing at firing temperatures of 700, 850 and 950oC. The results indicated that only the ceramic fired at 950oC conforms to the specifications for water absorption and mechanical strength.
