Abstract
Artificial interior stone is a decorative building material, which mostly consists of quartz. Sludge is generated during the stone manufacturing process, and the amount of sludge is increasing due to the high demand; however, most of the generated sludge is disposed of in landfills. In the present study, the effects of the sludge addition on the physicomechanical properties of mortars were investigated via flowability, penetration resistance, mercury intrusion, and compressive strength tests. The independent variable was the replacement ratio of the sludge to the fine aggregate. The test results showed that the addition of the sludge reduced the flowability, and initial and final setting times, while the percentage of the pores involved in the hydrates increased. The compressive strength of mortars with the sludge was improved compared to that of the mortars without the sludge. Quantum chemistry simulations were conducted to understand the strength enhancement mechanism of the specimens, and a straightforward machine learning-based model equation was proposed by applying the experimental variables and measurement results.
