Practical Notes

Ensure proper curing of precast units to prevent surface cracks and achieve the specified strength.

Verify manufacturer's test certificates for compliance with IS 9375 before procurement, especially for the transverse strength test.

Check for uniform finish and absence of sharp edges, which can be a safety hazard in public areas.
