MINERAL COMPOSITIONS BASED ON GYPSUM AND A MODIFYING COMPLEX FROM FUEL INDUSTRY WASTE
Abstract
Modern architecture and materials science are searching for new materials that are environmentally friendly and sustainable. These materials ensure a high quality of life and high energy efficiency in buildings. In addition to operational characteristics, the technological aspects of their production are important. This includes high mold turnover, ease of material fabrication, and the cost of obtaining them. These requirements can be met through the use of additive manufacturing for the production of buildings and their individual components. Implementing such technologies requires the use of specialized building mixtures. These mixtures can be used to create complex, geometrically complex, three-dimensional thin-walled elements of interior partitions and walls, as well as finishing materials and decorative elements. In this context, modern high-strength modified gypsum concrete is a promising material. Thanks to its processability, rapid curing, and ease of production, it is replacing other binders in high-tech areas of construction. This research study determined the compositions of gypsum concrete mixtures and obtained data on the strength properties in natural and water-saturated states, depending on the percentage of modifier. The developed modifier replaces binders with components derived from industrial waste from the fuel industry. This further enhances the environmental friendliness of the development, reduces its carbon footprint, and decreases its service life. The aim of this study was to investigate the feasibility of producing an effective gypsum concrete mix for additive construction with high technological and operational properties based on recycled waste from fuel power plants.
