Investigation of Thermal and Mechanical Behaviors of Plaster Mixed with Granite Cutting Waste

Abstract

This study investigated the usability of granite cutting waste in plaster. In the samples produced in the study, granite dust was observed with a scanning electron microscope, and it was homogeneously distributed in the microstructures. The presence of calcite, quartz, portlandite, hematite, and magnesium oxide phases in the samples was detected with an X-ray diffractometer. It was calculated that the highest compressive strength was obtained by adding 30% granite dust. In the samples whose thermal conductivities were examined by imaging with a thermal camera, it was determined that the lowest conductivity belonged to the sample containing 30% granite dust. This study revealed that plaster with high mechanical strength and low thermal conductivity could be produced by adding 30% granite dust. © 2025, Sakarya University. All rights reserved.
