Previous issue date: 2007-11-23 / The Industry of the Civil Construction has been one of the sectors that most contribute to the pollution of the environment, due to the great amount of residues
generated by the construction, demolition and the extraction of raw material. As a way of minimizing the environmental impacts generated by this industry, some governmental organizations have elaborated laws and measures about the disposal of residues from the building construction (CONAMA - resolution 307). This work has as objective the reutilization of residues compound of sand, concrete, cement, red
bricks and blocks of cement and mortar for the production of red ceramic, with the objective of minimizing costs and environmental impacts. The investigated samples
contained 0% to 50% of residues in weight, and they were sintered at temperatures of 950?C, 1000?C, 1050?C, 1100?C and 1150?C. After the sinterization, the samples
were submitted to tests of absorption of water, linear retraction, resistance to bending, apparent porosity, specific density, XRD and SEM. Satisfactory results were
obtained in all studied compositions, with the possible incorporation of up to 50% of residues in ceramic mass without great losses in the mechanical strength, giving
better results to the incorporation of 30% of residues in the fabrication of ceramic parts, such as roofing tiles, bricks masonry and pierced bricks / A ind?stria da constru??o civil tem sido um dos setores que mais tem contribu?do com a polui??o do meio ambiente devido a grande quantidade de res?duos gerados pela constru??o, demoli??o e extra??o de mat?ria prima. Como forma de minimizar os impactos ambientais gerados, alguns ?rg?os governamentais tem elaborado leis e medidas sobre a disposi??o de res?duos da constru??o civil (CONAMA resolu??o 307). Este trabalho tem como objetivo estudar o reaproveitamento de res?duos da constru??o civil composto de areia, concreto, cimento, tijolos vermelhos, e blocos de
cimento e argamassa na massa para fabrica??o de cer?mica vermelha, com o objetivo de minimizar custos e impactos ambientais gerados. As amostras investigadas continham 0% a 50% em peso de res?duo, sendo sinterizadas nas
temperaturas de 950?C, 1000?C, 1050?C, 1100?C e 1150?C. Ap?s a sinteriza??o as amostras foram submetidas a ensaios de absor??o de ?gua, retra??o linear, resist?ncia ? flex?o, porosidade aparente, massa espec?fica, DRX e MEV. Foram
obtidos resultados satisfat?rios em todas as composi??es estudadas, sendo poss?vel a incorpora??o de at? 50% de res?duo nas massas cer?micas sem grandes perdas
na resist?ncia mec?nica, apresentando melhores resultados para a incorpora??o de 30% de res?duos na massa de fabrica??o de pe?as cer?micas como telhas, tijolos de
alvenaria e furados
