RESUMO: A produção de resíduos sólidos urbanos (RSU) está em constante
crescimento, contribuído para um aumento dos impactes sobre o ambiente
e a sociedade. Para tentar mitigar estes problemas foram realizados e
ensaiados provetes cerâmicos ecológicos com incorporação de escórias
resultantes da incineração de resíduos sólidos urbanos. Deste modo,
pretendeu-se estudar o efeito do aumento da temperatura de cozedura, dos
900 ºC para os 1000 ºC, nos provetes com 0, 10 e 20% de escórias, sujeitos
ao ensaio de alteração por lixiviação em extrator soxhlet. Com base nos
resultados obtidos verificou-se um maior incremento da resistência nos
provetes cerâmicos com 20% de escórias, cozidos a 1000 ºC.
ABSTRACT: The production of urban solid wastes (USW) are constantly growing, carrying a huge impact on the environment and society. To try to mitigate these problems, ecological ceramic test-pieces, with the incorporation of ashes resulting from the incineration of urban solid waste, were carried out and tested. In this way, it was intended to study the effect of the increase of the firing temperature from 900 ºC to 1000 ºC in samples with 0, 10 and 20% of ashes, subject to the leaching alterability in soxhlet extractor. Based on the results, a greater increase of resistance was verified in the ceramic samples with 20% of ashes and fired at 1000 ºC.
