Previous issue date: 2015-01-22 / O presente trabalho consiste no estudo das caracter?sticas e propriedades tecnol?gicas de tijolos res?duo-cimento maci?os e vazados, formulados a partir de misturas bin?rias e tern?rias de cimento Portland, cascalho proveniente da perfura??o de po?os de petr?leo, com e sem adi??o de cinza do baga?o de cana-de-a?ucar que poder?o ser utilizados pela ind?stria, com o objetivo de melhorar seu desempenho, diminuir seu custo e aumentar 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 cimento CPIIZ-32, 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 e cinzas do baga?o de cana-de-a??car. Para a determina??o da mistura ?tima, estudou-se a inclus?o de teores de CBC (2%; 4%; 6%; e 8%) onde foram confeccionados 18 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 e cinza do baga?o de cana-de-a??car, tornando o tijolo res?duo-cimento com uma maior resist?ncia mec?nica e menor absor??o de ?gua. / In recent years the construction industry is a major world representation in the consumption of natural resources and generation of wastes which lead to a greater environmental impact. Thus, it is of fundamental importance to planning the consumption of non-renewable natural resources, in addition to waste management, reuse and incorporate them in the process of manufacturing new materials. The present work is the study of the characteristics and technological properties of solid waste-cement bricks and cast formulated from binary and ternary mixtures cement Portland, gravel from the oil well drilling, with and without addition of cane sugar ashes residue that can be used by industry, with the goal of improving performance, reducing cost and increasing its useful life. Was used CPIIZ-32 cement, drill cuttings residue of oil wells from drilling onshore wells in the municipality of Mossor? / RN, supplied by Petrobras and ashes of sugarcane bagasse. To determine the optimum mix was used to study the inclusion of gray levels (2%, 4%, 6% and 8%) where bodies were prepared 18-specimens for each formulation. The evaluation was made of bricks made from simple compression tests, weight loss by immersion and water absorption. The experimental results have proved the efficiency and the high potential for use of drill cuttings and ash cane bagasse, making the brick-cement residue with a higher strength and lower water absorption. The best result in terms of mechanical strength and water absorption, both for the binary and ternary blend formulation was 86% gravel, 12% cement and 2% ash.
