Análise quantitativa dos resíduos de gesso oriundos de obras da construção civil no município de Fortaleza

Abstract

The waste is primarily responsible for the generation of solid waste in the construction industry, most notably those related to the application of gypsum as a coating for walls and ceilings. In this work, we tried to quantify the rate of waste gypsum in four works located in the city of Fortaleza, by using two methods, which relate the quantity of mass of gypsum defendant with the amount of waste generated. The amount of waste generated could be due to the construction companies have studied segregated system of collection of such material. We studied two methods. The first parameter has been like a Mass of Gypsum Defendant (MGD), calculated taking into account the amount of gypsum obtained for the completion of service. In the second, the MGD is faced with the Quantity Theory Needed (QTN), which is determined from parameters such as the total area to be coated and Consumed Mass Index (CMI), which represents the ideal consumption without loss. It could be concluded that the technique of plaster folder is one that shows higher rates of waste and is not recommended, from an environmental standpoint, to be used as lining of walls and particularly roofs. There was also that the rate of waste to such works is very large, being larger than the values found in literature
