Abstract
Este trabalho teve por objetivo reformular uma típica massa de telhas produzida no município de Campos dos Goytacazes, RJ, variando a quantidade de areia. As matérias-primas, massa argilosa e areia, foram inicialmente submetidas a ensaios de caracterização mineralógica, química e física. Foram preparados corpos de prova por extrusão para queima nas temperaturas de 850, 950 e 1050 ºC. As propriedades avaliadas foram plasticidade, absorção de água, retração linear de queima e tensão de ruptura à flexão. Os resultados indicaram que as propriedades avaliadas melhoraram com a utilização de areia.
This work has as objective to reformulate a typical roofing tile body produced at Campos dos Goytacazes, RJ, Brazil, varying the amount of sand. The raw materials, clayey body and sand, were initially submitted to mineralogical, chemical and physical characterization tests. Specimens were prepared by extrusion to fire at 850, 950 and 1050 ºC. The evaluated properties were: plasticity, water absorption, firing linear shrinkage and flexural rupture strength. The results indicated that the evaluated properties improved with the use of sand.
