ANÁLISE DE PARÂMETROS FÍSICO-QUÍMICOS DO RESÍDUO DO PÓ DE GESSO DA CONSTRUÇÃO CIVIL PARA RECICLAGEM E PRODUÇAO DE PEÇAS DECORATIVAS

Abstract

The determination of the free water and water of crystallization, the contents of Calcium Oxide and Sulfuric Anhydride and the determination of the unit mass and grain size are some of the requirements in the norms ABNT NBR 12130: 2017 and ABNT NBR 12127: 2017, so that, soon after laboratory tests the gypsum dust residue from the construction industry can be reused. The present article aims to highlight the process of characterization of gypsum dust residue taking into account Physical-chemical attributes, in addition to reusing it to make decorative pieces. The results of the chemical and physical tests on the construction residue presented a good adaptation to the current norms, the decorative pieces obtained from the residue were viable.
