Abstract

Recently, with the development of the society associate with countless advances technological, benefits and harms have reaching the planet. A significant damage it has been soil contamination, as natural resources allocated underground, how aquifers. Sixteen slurry walls were prepared whose mixture of soil, of cement and of the clay was added with shredded scrap tires in distinct particles sizes. The characterization was realized by X-ray diffraction, by X-ray fluorescence spectrometry, by optical microscopy and by scanning electron microscopy. The slurry walls were evaluated for water drainage and contaminant retention capabilities showed significant efficiency in 50% of them, with featured for the mass concentrations of 1% of shredded scrap tires with retained # 14, # 18 and # 20 particle sizes. These results support the proposal of slurry wall model whose addition of extractors and other slurry wall would favor better quality control and of safety of the system. The performance of the slurry walls ensured the safe application of shredded scrap tires and as a consequence contributes so that tires discard is not inappropriate in the environment.
