Resumen

The data acquired from the conducted tests and analyses can be used in the design and development of energy-efficient low-carbon construction materials. Because magnesium oxybromide phases (MOB-318, MOB-518) are stable, non-defective and well densified, high mechanical resistance of MOB-based materials can be anticipated similarly to magnesium oxychloride cement (MOC). Analogous to MOC, precipitated MOB phases can accommodate a great volume of inorganic and organic fillers and aggregates, which enables the production of alternative construction materials for specific applications. MOB-based materials can thus meet specific technical, functional and performance criteria of building practice. As MOB-318 can transmit light, it can be used in the design of a novel, highly optically-transparent material for light-transmitting decorative panels, partition walls, facing panels, translucent bricks and other architectural elements. Another specific attribute of MOB is its marble-like appearance, which makes it suitable as a decorative material. MOB-based composites can also serve as flame retardants. As such, they can potentially find use in the form of insulation boards or ceiling slabs to ensure the fire safety of steel structure buildings.
