Previous issue date: 2010-04-22 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / One of waste produced on large scale during the well drilling is the gravel drilling. There are techniques for the treatment of the same, but there isn t consensus on what are the best in
terms of economic and environmental. One alternative for disposal of this waste and objective of this paper is the incorporation and immobilization of gravel clay matrix to
assess their technological properties. The Raw Materials used were characterized by the following techniques: Chemical Analysis by X-ray fluorescence (XRF), mineralogical analysis by X-ray Diffraction (XRD), Grain Size Analysis (FA) and Thermal Analysis by Thermogravimetry (TG) and thermodiferential (DTA). After characterizing, samples were formulated in the following percentages: 0, 5, 10, 15, 25, 50, 75, 100% (weight) of gravel
drilling, then the pieces were pressed, dried (110 ? C) and sintered at temperatures of 850, 950 and 1050 ? C. After sintering, samples were tested for water absorption, linear
shrinkage, flexural strength, porosity, density, XRD and test color. The results concluded that the incorporation of gravel drilling is a viable possibility for solid masonry bricks and
ceramic blocks manufacture at concentrations and firing temperature described here. Residue incorporation reduces an environmental problem, the cost of raw materials for manufacture of ceramic products / Um dos res?duos produzidos em grande escala durante a perfura??o de po?os de petr?leo ? o cascalho de perfura??o. Existem t?cnicas para seu tratamento, mas n?o existe um consenso sobre quais s?o as melhores do ponto de vista econ?mico e ambiental. Uma das alternativas de destina??o final deste res?duo e objetivo de estudo deste trabalho ? a incorpora??o e imobiliza??o do cascalho em matrizes argilosas para avaliar as suas propriedades tecnol?gicas. As Mat?rias-Primas utilizadas foram caracterizadas pelas seguintes t?cnicas:
An?lise Qu?mica por Fluoresc?ncia de raios-X (FRX); An?lise Mineral?gica por Difra??o de raios-X (DRX); An?lise Granulom?trica (AG) e An?lise T?rmica por Termogravimetria
(TG) e Termodiferencial (DTA). Ap?s a caracteriza??o, as amostras foram formuladas nas seguintes porcentagens: 0, 5, 10, 15, 25, 50, 75, 100% em peso de cascalho de perfura??o,
em seguida as pe?as foram prensadas, secas (110 ?C) e sinterizadas nas temperaturas de 850, 950 e 1050 ?C. Ap?s a sinteriza??o, as amostras foram submetidas a ensaios de Absor??o de ?gua, Retra??o Linear de Queima, Tens?o de Ruptura ? Flex?o, Porosidade Aparente, Massa Espec?fica Aparente, DRX e Ensaio de Cor. Os resultados obtidos conclu?ram que a incorpora??o de cascalho de perfura??o ? uma possibilidade vi?vel para a fabrica??o de tijolos maci?os de alvenaria e blocos cer?micos em determinadas concentra??es e
temperaturas de queima descrita neste trabalho. A incorpora??o deste res?duo al?m de amenizar um problema ambiental, reduz os custos com mat?rias-primas para fabrica??o de produtos cer?micos
