| Resumo: |
The accelerated growth of the urban population has caused an increase in demand natural resources, mainly water resources. Water treatment plants in Brazil use a conventional process for the treatment of water, turning water that is not suitable for consumption in drinking water, after which it is submitted to coagulation, flocculation, decantation, filtration, disinfection and fluoridation, respectively. However, this process presents as a residue the sludge. ETA sludge has many chemical elements such as aluminum, iron, silicon, titanium, magnesium and organic solids which, if discarded incorrectly, can negatively impact both human life and the environment. An alternative to solving this problem is the use of sludge generated in industrial applications. The present work seeks to evaluate the application of sludge in the civil construction industry through the manufacture of ecological brick. The proposal consists of the application of sludge as a partial substitute for the soil in the manufacture of the brick, which would consist of sand, soil, sludge and cement. The specimens were fabricated on the basis of the informations obtained in the literature. The evaluation of the same were determined according to Brazilian regulations after the tests of resistance to compression and water absorption. The bricks showed high water absorption, due to their porosity, although in this respect, they fit within the limits established by the norm (NBR 8492:2012). However, they did not reach the minimum compression strength established by the norm NBR 8492:3012, probably due to the high porosity of the bricks, being the samples rejected for application. |
