“…Nonetheless, frequencies around 2500 Hz, which include music or talking, are poorly masked by gypsum boards [34]. Thus, the use of other materials that can increase the sound insulation at the cited frequencies can be of interest for architects and engineers [26,27,[35][36][37][38][39]. The construction and building industry is continuously in the search of innovative solutions, particularly those that are more lightweight, sustainable, and cost-efficient [40][41][42].…”

Noise pollution has been identified as a cause of a broad spectrum of diseases, motivating researchers to identify building materials capable of attenuating this pollution. The most common solution is the use of gypsum boards, which show a good response for low frequencies but have a poorer response for high frequencies. In addition, due to environmental concerns associated with buildings, the use of materials that minimize environmental impacts must be favored. In this research, two biopolymers, a poly(lactic) acid and a bio-polyethylene, were filled with two typologies of calcium carbonate, and their soundproofing properties were tested using impedance tubes. In addition, the morphology of the fillers was characterized, and here we discuss its impact on the mechanical properties of the composites. The results showed that the incorporation of calcium carbonate into bio-based thermoplastic materials can represent a strong alternative to gypsum, because their mechanical properties and sound barrier performance are superior. In addition, the inclusion of mineral fillers in thermoplastic materials has a positive impact on production costs, in addition to preserving the advantages of thermoplastics in terms of processing and recycling. Although the use of carbonate calcium decreases the mechanical properties of the materials, it enables the production of materials with insulation that is four-fold higher than that of gypsum. This demonstrates the potential of these materials as building lightweight solutions.

“…Moreover, the better performing MgO boards, particularly those produced from MOC cement, were found to have superior or comparable performance with that of conventional board types such as fibre cement, gypsum plasterboard and wood-based boards using commonly adopted test methods for the assessment of sheeting materials [25]. These findings also suggest that MgO boards, manufactured appropriately, perform adequately initially, and subsequently do not provide any indication that they will not continue to do so over their intended service life.…”

“…The current study focuses on the effect of moisture and temperature on MgO boards, particularly boards produced with MOC cement, as it was MOC based boards that were identified to have caused the issues in Denmark. Extended exposure durations and different types of exposure conditions are investigated and compared with previous studies [24,25]. Specifically, MgO boards were exposed to high relative humidity (RH) and various temperatures for extended durations up to 840 days.…”

“…A study by Rusthi et al [42] analyzed the details of thermal properties tests and fire resistance tests of LSF wall systems (Light Steel Frame) lined with MgO boards with different configurations. The thermal properties tests performed on the two types of MgO boards showed that MgO boards lose a large amount of weight at increased temperatures, approximately 50% and 40% of the initial weight, whereas gypsumboard loses 15% of weight when used in a standard way.…”

Growing global environmental problems force us to think about their impact and search for ways to protect the environment. While the construction industry and the production of construction materials contribute to environmental pollution, they also offer great potential for addressing many environmental problems. Important opportunities exist in the use and processing of a whole host of industrial and construction waste and in the use of mineral resources. Among such mineral resources is magnesite, whose deposits in Slovakia are abundant. The current sustainability trends impose strict requirements on construction materials and products, favoring solutions with sufficient ecological and efficiency performance characteristics. With this focus on efficient and sustainable solutions in mind, the objective of this research was to analyze magnesium oxide construction boards, as they are the most commonly used construction product based on MgO. The specific MgO-based boards that were studied were applied in selected constructions built using the so-called dry method of construction and were compared with traditional material solutions. The research methodology is based on an analysis of computational models of the proposed variants to determine selected thermal-technical parameters. The analyses of external and interior structures presented in this work suggest that when boards based on MgO and traditional materials are used for coating constructions built using the dry method of construction, the former provide certain benefits in terms of energy accumulation, improving living comfort, and in terms of the fire resistance of constructions, improving overall safety. The conclusion of the presented article is devoted to discussions with works that addressed various perspectives on the application of MgO in the field of materials research. The findings from this analysis are beneficial especially in terms of expanding the knowledge in the area.
