Magnesium oxide (MgO) has a rich history as a building material, with its use dating back to ancient civilizations. Its durability and versatility have made it a preferred choice in various monumental constructions throughout history.
Great Wall of China: Constructed over several dynasties, the Great Wall utilized magnesium oxide-based mortar to bind stones and bricks. This choice contributed to the wall's enduring strength and resilience against natural elements.
Roman Architecture: Romans incorporated magnesium oxide into their building practices, notably in structures like the Pantheon. The magnesia-based cement provided enhanced durability and longevity, evident in the survival of these structures over millennia.
In the 20th century, the construction industry saw a shift towards more cost-effective materials such as gypsum, plywood, and Portland cement. However, the superior properties of magnesium oxide led to its resurgence in the form of MgO boards. These boards offer benefits like fire resistance, moisture resistance, and environmental sustainability, making them a favorable alternative in modern construction.
Taipei 101: This skyscraper in Taiwan, once the world's tallest building, incorporates MgO boards extensively for interior walls and ceilings. The material's fireproofing qualities and environmental benefits contributed to the building receiving a Platinum rating under the LEED certification system.
Brooklyn Bridge: The base of this iconic New York City bridge is constructed using Rosendale cement, a mixture containing magnesium oxide. This choice of material has contributed to the bridge's longevity and structural integrity since its opening in 1883.
Fire Resistance: MgO boards are non-combustible, providing superior fire resistance compared to traditional materials.
Moisture Resistance: They are highly resistant to moisture, preventing issues like mold and mildew, which are common in materials like gypsum.
Environmental Sustainability: MgO boards are eco-friendly, often produced with lower carbon emissions and being recyclable, aligning with modern sustainable building practices.
The historical significance and modern resurgence of magnesium oxide in construction highlight its enduring value as a building material. From ancient wonders like the Great Wall of China to contemporary architectural feats like Taipei 101, MgO continues to play a crucial role in building durable, safe, and sustainable structures.
