What are the standard sizes of mosaic tiles according to IS 13712?

Standard sizes are 200x200mm, 250x250mm, and 300x300mm, with thicknesses of 20, 22, and 25mm respectively (Table 1).

What is the maximum allowable water absorption for mosaic tiles?

The average water absorption by mass shall not exceed 10 percent (Table 2).

What is the difference between General Purpose and Heavy Duty tiles?

Heavy Duty tiles have higher requirements for transverse strength (2.5 MPa vs 2.0 MPa) and resistance to abrasion (max wear of 2.0mm vs 3.5mm) as per Table 2.

What is the minimum thickness for the top mosaic layer?

The thickness of the wearing layer (mosaic layer) shall not be less than 5 mm (Clause 6.2).

This standard specifies the requirements for materials, manufacture, dimensions, finish, and physical properties for precast cement concrete mosaic tiles. It classifies tiles into general purpose and heavy-duty types and outlines the test methods for verifying their performance, such as strength, water absorption, and resistance to abrasion.

Specifies requirements for precast cement concrete mosaic tiles used for flooring, including dimensions and physical properties.

Quick Reference Values

Practical Notes

Ensure tiles are properly cured for at least 21 days as per Clause 5.4 to achieve desired strength and durability.

The choice between 'General Purpose' and 'Heavy Duty' tiles should be based on the anticipated foot traffic of the area. Heavy-duty tiles are essential for commercial and high-traffic public areas.

Verify the thickness of the top wearing layer (min 5 mm) during quality checks, as an inadequate layer thickness is a common defect that leads to premature wear.
