Abstract:
The use of ornamental stone residues, mainly granite, has been researched in order to reduce the environmental impact. One way to reuse them is to incorporate the granite residue into the plaster mortar. This work aims to present the influence of the granite residue on the properties of the fresh state in plaster mortar. Results of the use of the granite residue with addition in gypsum mortar, in fractions of 0%, 25%, 50%, 75% and 100% in relation to the sand mass were presented. For gypsum mortars produced, flow table, mass density, incorporated air content, water retention, and the squeeze-flow method were evaluated to understand their main rheological characteristics. The analysis of the results allows to conclude that the use of the granite residue as an addition in gypsum mortars is technically feasible only for the contents of 25% and 50%, and that 25% of addition is the content that presents the best performance
