Physical and mechanical performance of magnesium-based construction boards: A comparative study

The use of sheeting materials within the construction industry is becoming increasingly common as building and way they are used evolves. Recently, magnesium-based boards have received more attention alternatives for traditional materials. This due to some their enhanced properties, particularly fire resistance lower embodied carbon. However, lack standardised documentation has caused concern regarding composition, performance long-term behaviour. paper evaluates test methods commonly when assessing boards. A comparison between relatively novel also conducted. Physical, mechanical durability properties investigated. Magnesium-based can provide good bending strength values water absorption behaviour which comparable with other board types. Findings demonstrate exposed soak-dry freeze-thaw cycles. They suffered small changes in strength, similar that fibre cement superior gypsum plasterboards wood-based
