MGO Board and its Usefulness for the Modern Age


The utilization of MgO returns numerous hundreds of years, nearly to the Pyramids. It was initially used to make mortars for brick work development. These days, in numerous nations, MgO is frequently utilized for mortars. In North America, MgO concrete is utilized more often than not.

The cutting edge utilizationof MgO to make sheathing boards returns quite a few years. MgO sheets have been utilized in Asia and the Middle East on some huge, world-class ventures, especially for parcels and fire dividers.


Magnesium oxide board "MgO board" is a processing plant made, non-protecting sheathing board item. It tends to be utilized for various applications including divider and roof linings, belts, soffits, tile support and underlayment. It is made of magnesium oxide, a sort of mineral concrete, and is usually called basically "MgO" (articulated emm-well gracious) because of its synthetic piece of magnesium (substance image Mg) and oxygen (concoction image O). Consider MgO a kind of sheathing board–similar to drywall or concrete board–yet with much-improved attributes, for example, imperviousness to fire, weather ability, quality, protection from form and mold, etc.

MgO is accessible in numerous structures, and for building development comes in different thicknesses and sheet sizes. It additionally comes in different evaluations, for example, smooth completions, unpleasant surfaces, and utility evaluations. It is white, beige or light dim in shading, and has a "hard" stable when sent a clear message to some degree like portland concrete board. There are many organizations that make MgO board, the vast majority of which are in Asia. There are a few huge makers; however most are little nearby producers who serve a locale.

Notwithstanding the base material of MgO, different kinds of magnesium 'concretes', wood flour, and different added substances are incorporated to improve assembling and upgrade different properties. Most MgO board have some sort of stringy fortification inside the center or potentially on the face. Frequently this appears as glass work, filaments, or a fine screed. MgO sheets additionally contain different added substances to improve adaptability and climate capacity. As such, there are different sorts of MgO board; however, most are basically the equivalent as far as their essential organization.

MgO sheets are made as individual pieces that are sliced to length as they are poured onto a throwing plate. The underlying set happens evenly, however the last fix happens vertically or with spacers between the sheets. The MgO is thrown in a fluid slurry-like structure (a blend of MgO powder, and different added substances and water) and sets up by concoction response - much like concrete does in stucco or cement. The cast sheets are then relieved at encompassing temperature. MgO sheets don't contain asbestos; however, some have various kinds of small scale fiber fortifying. This strengthening is independent from the surface scrim, and is a piece of the MgO slurry used to cast the MgO boards.

Using Magnesium Oxide Wallboard as an Alternative Building

Magnesium Oxide is a versatile material widely used in Asian residential and commercial buildings. Major,(magnesite) deposits are found in China, Middle East, and Canada. Egypt is one of the Middle East countries that mines magnesite. Magnesium Oxide wall cladding is a new technique in Egyptian construction field, some of Cairo’s modern buildings facades applied locally manufactured Magnesium Oxide wallboard as external shaping material. The research paper illustrates through site observations followed by a comparative study between Cairo’s traditional façade shaping technique using Cement Plaster on metal lath and using Magnesium Oxide wallboards, The research ends up by showing the advantages and disadvantages of using Magnesium Oxide wallboard for external claddings in Cairo.
Methodology:
Historical background about the use of Magnesium Oxide material as building façade cladding material.
 Illustration of the environmental sustainability of Magnesium Oxide material.
 Environmental and financial comparison of building facades shape forming traditional cement plaster on
expanded metal lath technique used in Cairo Egypt and external wall cladding using Magnesium Oxide wallboards.
 Site investigation on the results of applying Magnesium Oxide wallboards as a new shape forming
technique in modern Cairo buildings showing its advantages and disadvantages and its application
capabilities in Cairo’s weather conditions.
Purpose and use:
Magnesium Oxide board is a factory-made, non-insulating sheathing board product. It can be used for a
number of interior or exterior applications including wall and ceiling linings, fascias, soffits, countertop, shaftliner
& area separation wall board, exterior sheathing, substrates for coatings and insulated systems such as:
direct-applied finish systems, (painting & Stucco), it can be used as tile backing and under laments.
Magnesium Oxide is widely used primarily as wallboard alternative to conventional gypsum-based drywall
–but with much improved characteristics such as fire resistance, weather ability, strength, resistance to mold and
mildew and so on. The Magnesium Oxide boards can be scored and snapped, sawed, drilled and fastened to
wood or steel framing. Magnesium Oxide boards are a good example of the advances made in construction
materials to meet changes in building safety and durability codes. Magnesium Oxide is available in many
forms, and for building construction purposes it is produced in various thicknesses and sheet sizes with various
grades, such as smooth finishes, rough textures and utility grades. It is white, beige or light gray in color.
