Determinação da composição da água da percolação oriunda de tijolos de adobe de solocimento e cal reforçados com fibras de papel kraft reciclado

Abstract

Modern l ife generates a huge amount of waste and indust r ies have encountered a great chal lenge to give a purpose to this mater ial . With the awareness that the resources of our planet are f ini te, i t is necessary to use every resource exploi ted in i ts total i ty, giving i t the most noble end possible. The civi l indust ry is among the areas that exploi t the most raw mater ials, thus requi r ing a l iabi l i ty wi th al l the waste generated by i ts act ivi ty. For this reason, new mater ials incorporat ing by-producto have been developed, seeking to maintain the qual i ty and guaranteeing the envi ronmental standards requi red by the legislat ion. The object ive of this work was to evaluate the qual i ty of the leaching water of cement and l ime blocks, incorporated wi th kraf t paper f ibers f rom cement bags. For the character izat ion of the percolat ion water samples, the fol lowing tests were per formed: pH, elect r ical conduct ivi ty, hardness and spect rophotomet ry. The analyzes showed that the percolated water of the blocks is alkal ine and presents conduct ivi ty, hardness and color wi thin the acceptable l imi ts. In this sense, the blocks made wi th kraf t paper f iber are considered stable and do not release substances above the levels al lowed by Brazi l ian legislat ion.
