Previous issue date: 2011-03-30 / In the State of Rio Grande do Norte potteries are distributed in several counties
in the four meso, which are: West Potiguar, Center Potiguar, Agreste Potiguar and East
Portiguar. The ceramics, mostly, are responsible for products used in construction as
bricks, tiles and white brick and wood used as fuel. This paper had a primary focus in
the region of Serid?. The furnaces in this region, used to manufacture bricks are
configured Caieira and Valt, in most of them using principles rustic, usually operated in
an empirical way, using principles of control rather primitive, predominantly visual
control. The focus of this study was to analyze the differences in the thermophysical,
mechanical and geometric characteristics of bricks produced by Caieira and vault
furnaces, using the NBR 15720 and the evaluation of energy efficiency in both furnaces.
Thermophysical characteristics were analyzed through tests to determine the water
absorption obtained from the difference between dry mass and wet mass of the sample
and analysis of the thermal gradient, the mechanical characteristics from determination
of the compressive strength of ceramic brick popularly known as bricks and also
analyzed the geometrical characteristics of the bricks in order to verify the homogeneity
of manufacturing. The tests showed that the energy difference of the two furnaces is not
considered responsible for a significant difference in the properties of the products / No estado do Rio Grande do Norte as olarias s?o distribu?das em diversos
munic?pios, nas quatro mesorregi?es, que s?o: Oeste Potiguar, Centro Potiguar, Agreste
Potiguar e Leste Potiguar. As cer?micas, em sua maioria, s?o respons?veis por produtos
utilizados na constru??o civil como tijolos furados, tijolos brancos e telhas e utilizam
como combust?vel a lenha. Este trabalho teve um enfoque principal na ind?stria
cer?mica na regi?o do Serid?. Os fornos nessa regi?o, utilizados para a fabrica??o de
tijolos furados possuem a configura??o caieira e ab?bada, geralmente operados de
forma emp?rica, utilizando princ?pios de controle bastante primitivos, sendo
predominante o controle visual. O objetivo deste trabalho foi analisar as diferen?as nas
caracter?sticas termof?sicas, mec?nicas e geom?tricas dos tijolos produzidos pelos
fornos caieira e ab?bada, utilizando a NBR 15720, que trata de blocos de alvenaria e a
avalia??o do rendimento energ?tico de ambos os fornos. Foram analisadas as
caracter?sticas termof?sicas por meio dos ensaios de determina??o da absor??o de ?gua
obtido a partir da diferen?a entre a massa seca e a massa ?mida das amostras e da
an?lise do gradiente t?rmico; as caracter?sticas mec?nicas a partir da determina??o da
resist?ncia ? compress?o dos blocos cer?micos popularmente conhecidos como tijolos e
tamb?m foram analisadas as caracter?sticas geom?tricas dos tijolos com o objetivo de
verificar a homogeneidade da fabrica??o. Os ensaios realizados mostraram que a
diferen?a energ?tica dos dois tipos de fornos analisados n?o ? respons?vel por uma
diferen?a significativa nas propriedades dos produtos produzidos
