The soil-cement bricks are one of the alternatives to masonry construction. These elements, after a short curing period, provide compressive strength similar to that of solid bricks and ceramic blocks, and the higher the resistance the higher the amount of cement used. We used the soil from the city of S?o Jos? do Mipibu / RN, the banks of the River Baldun, cement CPIIZ-32 and residue of drill cuttings from oil wells drilling onshore wells in the town of Mossley, RN, provided Petrobras. To determine the optimum mix, we studied the inclusion of different residues (100%, 80%, 70%, 60% and 50%) where 15 bodies were made of the test piece. The assessment was made of bricks made from simple compression tests, mass loss by immersion and water absorption. The experimental results proved the efficiency and high utilization of the waste from the drilling of oil wells, making the brick-cement-soil residue with a higher strength and lower water absorption. The best result in terms of mechanical strength and water absorption for the ternary mixture was 10% soil, 14% cement and 80% residue. In terms of binary mixtures, we obtained the best result for the mix-cement residue, which was 14% cement incorporated in the residue / O presente trabalho consiste no estudo das caracter?sticas e propriedades tecnol?gicas de tijolos solo-cimento formulados a partir de misturas bin?rias e tern?rias de cimento Portland, areia, ?gua, com e sem adi??o de cascalho proveniente da perfura??o de po?os de petr?leo, que poder?o ser utilizados pela ind?stria, com o objetivo de melhorar seu desempenho e diminuir seu custo utilizando o res?duo e, conseq?entemente, aumentando sua vida ?til. Os tijolos de solo-cimento constituem uma das alternativas para a constru??o em alvenaria. Esses elementos, ap?s pequeno per?odo de cura, garantem resist?ncia ? compress?o simples similar ? dos tijolos maci?os e blocos cer?micos, sendo a resist?ncia tanto mais elevada quanto maior for ? quantidade de cimento empregada. Foi utilizado o solo proveniente do Munic?pio de S?o Jos? do Mipib?/RN, as margens do Rio Baldun, cimento CPIIZ-32 e res?duo de cascalho de perfura??o de po?os de petr?leo proveniente da perfura??o de po?os Onshore, no munic?pio de Mossor?/RN, fornecido pela Petrobras. Para a determina??o da mistura ?tima, estudou-se a inclus?o de teores de res?duos diferenciados (100%; 80%; 70%; 60% e 50%) onde foram confeccionados 15 corpos-de-prova. A avalia??o dos tijolos confeccionados foi feita a partir de ensaios de compress?o simples, perda de massa por imers?o e absor??o de ?gua. Os resultados experimentais comprovaram a efici?ncia e o elevado potencial de utiliza??o do res?duo proveniente da perfura??o de po?os de petr?leo, tornando o tijolo de solo-cimento-res?duo com uma maior resist?ncia mec?nica e menor absor??o de ?gua. O melhor resultado, em termos de resist?ncia mec?nica e absor??o d ?gua, para a mistura tern?ria, foi de 10% de solo, 14% de cimento e 80% de res?duo. Em termos de misturas bin?rias, obteve-se o melhor resultado para a combina??o cimento-res?duo, que foi de 14% de cimento incorporado no res?duo
