What are the primary binder materials for this type of flooring?

Calcined magnesite and magnesium chloride, which react to form the magnesium oxychloride cement matrix.

Where is magnesium oxychloride flooring typically used?

It is used for heavy-duty, dust-free, and jointless floors, typically in older industrial and commercial buildings.

Can magnesium oxychloride floors be washed frequently with water?

No, prolonged exposure to water deteriorates the flooring matrix. It should be maintained with wax or oil polishes.

This standard specifies the requirements for materials such as calcined magnesite, magnesium chloride, fillers, and aggregates used in the manufacture of magnesium oxychloride (magnesite) flooring compositions. It is used by engineers to ensure quality control for materials going into heavy-duty, jointless flooring installations.

Quick Reference Values

Magnesium chloride specificationMust conform to IS 254

Calcined magnesite minimum MgO content87% by mass (typical requirement for standard structural magnesite)

Fineness of calcined magnesiteShould pass through 90-micron IS sieve

Practical Notes

Magnesium oxychloride flooring is highly susceptible to water damage and should not be specified for continuously damp, external, or wet areas.

Ensure that fillers and aggregates are chemically inert to prevent deleterious reactions with the magnesite binder.

The performance of the floor is highly dependent on the correct ratio and purity of the magnesium chloride and calcined magnesite used.
