dc.description.resumo	This study evaluates the behavior of a ceramic waste material in partial and total substitution of a mineral additive, commonly used in oil well cement slurries, when exposed to high temperatures and pressures. The samples were submitted to a cycle of low temperature (38°C) for 28 days, followed by exposure to 280oC and 6.5MPa (1000 psi) for 3 days. The evaluation was made by compression testing and X-ray diffraction (XRD). The results showed that cement pastes containing ceramic waste, when combined with silica flour, produced hydrated products of low Ca/Si ratios which maintained the compressive strength at satisfactory levels	pt_BR
