Oxychloride Floorings
French scientist SOREL in nineteenth century discovered an
excellent cement formed from the combination of magnesium oxide
and magnesium chloride. This
cement type is now known by many different names such as Sorel,
magnesite and magnesium oxychloride cement.
Chemoxy cement floor are chemical composition magnesium
oxychloride cement, which has many superior properties to Portland
cement and has the major commercial application for various types
of engineering units for light medium and heavy industrial
floorings.
As
mentioned above, Chemoxy cement floor has many superior
properties compared to Portland cement.
It does not require wet curing, has high fire resistance,
low thermal conductivity, good resistance to abrasion.
It has excellent load bearing capacity because of its high
transverse and crushing strengths, 475 - 680 Kg/cm2 are not
uncommon. Chemoxy cement floor also bonds very well to a variety
of inorganic and organic aggregates, giving a cement that has
early strength, insectidal properties, resilient, conducting and
is unaffected by oil, grease and paints.
The
main bonding phases found in hardened cement pastes are Mg(OH)2,
3Mg(OH)2.MgCl2
8H2O
(3-form) and 5Mg(OH)2.MgCl2.
8H2O
(5-form). 5-form is the phase with superior mechanical
properties and is formed using a proper molar ratio.
The
reactivity of the MgO influence reaction rates and products, thus
affecting the development of the strengths.
The magnesium oxide should conform to certain requirements
of chemical and physical properties.
Conditions of calcinations, particle size and the active
lime content must be carefully controlled. Chemoxy chemical
composition conforms to the above requirements and is specially
produced for making oxychloride floorings to yield a plastic mix
of satisfactory workability use.
The
magnesium oxychloride phase is not stable in prolonged contact
with water, and will result in the leaching of magnesium chloride.
Various additives have been added to try and combat this
problem of water resistance, with varying degrees of success.
Over a period of time, atmospheric carbon dioxide will
react with magnesium oxy chloride to form a surface layer of Mg2(OH)ClCO3
3H2O.
This layer serves to slow the leaching process.
Eventually additional leaching results in the formation of
hydromagnesite, 4MgO.3CO3.4H2O,
which is insoluble and enables the cement to maintain structural
integrity.

ASKED QUESTIONS |
| MATERIAL: |
CONFORMS
TO IS: 658 OF 1982 |
| WHERE
IT CAN BE LAID: |
Chemoxy
floors can be laid on any hard surface such as cement
slab, wooden and metallic surfaces. |
| PROCEDURE
OF LAYING |
Chemoxy
floor consists of part A (powder) and part B (liquid).
The existing floor should be cleaned thoroughly (free
of dampness, grease, oil and loose concrete). Wooden
battens of 5mm thick are properly secured at regular
intervals on the existing floor. A & B are mixed
to a uniform consistency and is then laid on the floor
and are trowel led finish |
| CAN
THE FLOOR BE CUT OPENED REPAIRED |
YES.
The floor can be cut opened with the help of the
mechanical tools like chisel, hammer or electric
operated cutting machine. The patch can be refilled
with Chemoxy material and the repaired patch will
almost match with the old floor. Also the repaired
patch fuses with the old floor and does not come out
like cement floor due to the fusion property of the
floor. |
| THICKNESS |
Minimum
thickness required is 25mm. The thickness can be
increased as per the requirement. |

| COLOUR |
Chemoxy

green, gray, blue and yellow. The shades of the sample
are for reference purposes only and exact matching of
the shade cannot be guaranteed. Also the secondary
