“…Depending on the characteristics of this waste, its disposal can cause damage to the health of the population and the environment. In this context, the paint industry can be considered as one of the industries that generate produces a high volume of solid waste [1][2][3][4]. According to the Brazilian Association of Paint Manufacturers (ABRA-FAT), the sector sold 10,026 billion reais, in 2016.…”

Before being reused, industrial waste needs to have its composition determined so that in the future, it will not cause harm to the people and to the environment. The present study proposes the characterization and reuse of the residue remaining in the production of leveling masses and textures as a component in the Portland cement mortar specimens in order to analyze the effects on the axial compressive strength. The residue generated was characterized by Infrared (IR) Absorption Spectroscopy, X-ray Diffraction (XRD), Atomic Emission (AE) and Thermogravimetric Analysis (TG/DTG). All analyzes confirmed the predominant presence of dolomite (CaMg(CO 3 ) 2 ) as the main component and absence of potentially toxic metals. The addition of 10% of the residue on the cement and sand mass or the replacement of 10% of the sand mass in the mortars had small impact on the axial compression strength. The standard deviation values found lead to the conclusion that the compressive strength of the studied mortars can be considered statistically similar.
