Increasing the Efficiency of Cement based on Asphalt Plant Filter Waste

This article presents the production process of D20 400 grade cement at the Sherabad Cement Plant, located in the Surkhandarya region. In the manufacturing process, technogenic waste obtained from industrial enterprises of the Surkhandarya region was utilized. The main objective of this study is to reduce energy consumption in clinker production, enhance environmental sustainability, and minimize the use of natural resources. For this purpose, the filter waste from an Asphalt Plant was selected as a technogenic additive. The physical and chemical properties of the cement samples produced with the inclusion of this filter waste were examined, and the optimal production ratio was determined. The properties of the obtained cement samples were analyzed and compared with those of conventional cement. Based on the research results, it was found that adding 7% Asphalt Plant filter waste to the composition of D20 400 grade cement yielded the most favorable outcome. Additionally, key indicators such as density, specific surface area, liter The ight, compressive strength, sieve analysis, setting time, and volume stability of the resulting cement samples are evaluated. The obtained results were further analyzed using IR Spectroscopy, Thermogravimetric Analysis (TGA), and Differential Thermal Analysis (DTA).
