Uma abordagem sustentável no desenvolvimento de um material com alta capacidade reflexiva a partir de resíduo da construção civil

Abstract

The construction industry generates a lot of waste, called Waste Construction. Eliminating this waste has become a problem for big cities since their final destination are almost always landfills and dumps. In order to reduce its environmental impacts, ways to reuse such waste are necessary to create. Therefore, this work aims to reuse such waste in a mixture with zinc oxide to obtain a material with reflective power, and can serve as raw material for the manufacture of reflective tracks used as sensors for traffic guidance. There are various types of sensors that help drivers of vehicles for traffic on roads, including the sensors for traffic guidance, which are composed by a band that reflects light coupled to a base structure fixed to the ground. Zinc oxide is a substance used to manufacture most of these tracks, due to its ability to reflect light. With the purpose to find the best composition for the development of the material, we performed a Factorial Planning, varying the mass of the Construction waste and zinc oxide.Using this method and with the assistance of thermoluminescence analysis, we obtained a good quality reflective material, which may contribute to the reduction of environmental impacts caused by the disposal of construction waste.
