Previous issue date: 2008-03-26 / The ceramics industry in Piau? is nowadays with 55 industries where 11 are in Teresina which is the mainstream of the state, producing 55 million shingles; in which 10 % is of this production is wasted being sometimes thrown on the margins of rivers, roads and highways provoking an environmental degradation. The main goal of this work is to verify the potential of producing semi porous ceramic using grog of
shingles, on the first part of this work bodies-of-proof were produced from a basic formula of an industry, doping it with 5 %, 10 %, 15 % and 20 % in mass and in the second part of this work some bodies-of-proof were produced from a formula where one raw material was substituted by 50 % of grog and another substituting it all by grog, bodies-of-proof made of a basic formula previously announced was used for experiment control.The grog and the raw materials were characterized by: particle size analysis , thermal differential analysis, X ray diffraction , X ray fluorescence, an thermal gravimetric analysis and rational analyses. The bodies-of-proof were
sintetisized in an industrial oven obeying the normal cycle adopted by an industry, with peak temperatures of 1135 oC and a fast burning cycle of 25 minutes having as energetic fuel liquefied petroleum gas . The pieces that were obtained by this were submersed in rehearsed physics of: water absorption of, apparent specific mass, apparent porosity, lineal retraction, rupture tension to the flexural and dilatometry; mineralogical analysis for X ray diffraction; and microstructural for electronic microscope of sweeping. For all the formulas with addition of grog, superior priorities
to the requested by the requirements for semi porous and for the formula to F2-2,5 superior priorities to standard formulas which justifies the incorporation of the shingles in mass for the semi porous ceramic / A ind?stria de cer?mica vermelha Piauiense, atualmente com 55 ind?strias onde 11 somente em Teresina sendo o maior p?lo do Estado, produz pouco mais de 55 milh?es de telhas, das quais aproximadamente 10 % dessa produ??o s?o
desperdi?adas sendo ?s vezes jogadas ?s margens dos rios e estradas, provocando uma degrada??o ambiental. O objetivo deste trabalho ? verificar a potencialidade de se produzir revestimento cer?mico semi-poroso utilizando chamote de telhas, na primeira parte do trabalho foram produzidos corpos-de-prova a partir da formula??o b?sica de uma ind?stria de revestimento, dopando-a com 5 %, 10 %, 15 % e 20 %
em massa, e uma segunda parte deste trabalho foram produzidos corpos-de-prova a partir de uma formula??o onde se substitu?a uma das mat?rias-prima por 50 % de
chamote e outra substituindo a mesma totalmente por chamote, sendo usado para controle do experimento corpos-de-prova confeccionados a partir de uma formula??o
b?sica citada anteriormente. O chamote e as mat?rias-prima foram caracterizados por: an?lise granulom?trica, an?lise t?rmica diferencial, an?lise termogravim?trica difra??o de raios X, fluoresc?ncia de raios X, e an?lise racional. Os corpos-de-prova foram sinterizados em forno industrial de rolo, obedecendo ao ciclo adotado por uma ind?stria de revestimento, com temperatura de pico igual a 1135 ?C e ciclo de queima r?pido de 25 min, tendo como matriz energ?tica o g?s liquefeito de petr?leo. As pe?as assim obtidas foram submetidas aos ensaios f?sicos de: absor??o de ?gua, massa espec?fica aparente, porosidade aparente, retra??o linear, tens?o de ruptura ? flex?o e dilatometria; an?lise mineral?gica por difra??o de rios X; e microestrutural
por microsc?pio eletr?nico de varredura. Obteve-se para todas as formula??es com adi??o de chamote, propriedades superiores ?s das exigidas pelas normas em vigor
para revestimento semi-poroso e para a formula??o F2-2,5 propriedades superiores ? formula??o padr?o o que justifica a viabilidade da incorpora??o do rejeito de telhas em massa para revestimento cer?mico semi-poroso
