MGO
board /Magnesium oxide boad Magnesium
oxide, more commonly called magnesia, is a versatile mineral
that when used as part of a cement mixture and cast into thin
cement panels under proper curing procedures and practices can be
used in residential and commercial building construction. Some
versions are suitable for a wide range of general building uses and
for applications that require fire resistance, mold and mildew
control, as well as sound control applications and many other
benefits. As an environmentally friendly building
material, magnesia board has strength and resistance due
to very strong bonds between magnesium and oxygen atoms that form
magnesium oxide crystals (with the chemical formula
MgO).
Magnesia
boards are used in place of traditional gypsum drywall as
wall and ceiling covering material and sheathing. It is
also used in a number of other construction applications such as
fascias, soffit, shaft-liner and area separation, wall
sheathing, and as tile backing (backer board) or as substrates for
coatings and insulated systems such as finish systems, EIFS, and
some types of stucco.
Magnesia
cement board for building construction is available is various
sizes and thickness. It is not a paper-faced material. It generally
comes in a light gray, white or beige color. Numerous versions and
value of grades exist including smooth face, rough texture,
utility, versatile grades as well as different densities and
strengths for different applications and uses.
Presently
various magnesia cement boards are widely used in Asia as a primary
construction material. Some versions have been designated as the
official construction specified material of the ***8 Summer
Olympics and some versions are used extensively on the inside
and outside of all the walls, fireproofing beams, and as the
sub-floor sheathing in one of the world\'s tallest
buildings, Taipei **1, located in Taipei,
Taiwan.
Magnesia
cement is manufactured in a number of areas around the world,
primarily near areas where magnesia based ore (periclase) deposits
are mined. Major deposits are found in China, Europe, and
Canada.[1] Magnesia ore deposits in the US are negligible.
Estimates put the use of magnesia board products at around 8
million ft² in Asia alone. It is gaining popularity in the US,
particularly near coastal regions.
