Experimental analysis of physical properties of lightweight gypsum plasterboard

Abstract

This article presents an experimental analysis of a newly developed gypsum plasterboard for dry construction. The new board has a density that is 40 kgm⁻³ lower than existing boards and was created with an emphasis on conserving resources and reducing the energy consumption required for its production. Because gypsum is the most energy-intensive raw material, the research team focused on minimizing its content. As a result, the new board uses 12 % of mass less gypsum, which translates into an approximately 6 % reduction in CO₂ emissions from the annual production process. Crucially, this was achieved while meeting the relevant standard requirements for mechanical, thermal-technical, and fire performance, and maintaining the board’s “sustainable” user properties. The article details the experimental analysis conducted on key mechanical and thermal-technical parameters of the board.
