Can these blocks be used for structural or load-bearing purposes?

No, they are exclusively designed and specified for non-load bearing interior partitions.

Which code should be referred to for testing these gypsum blocks?

IS 2542 (Methods of test for gypsum plaster, concrete and products) is used for testing compressive strength and water absorption.

What is the primary advantage of hollow gypsum blocks?

They provide a lighter partition wall solution, which reduces dead load on the structure and can offer improved acoustic properties.

Practical Notes

Gypsum blocks are strictly meant for interior dry areas; they must not be used in external walls or wet areas (like bathrooms) without specialized waterproofing.

Hollow gypsum blocks are excellent for reducing the dead load on floor slabs while maintaining the required partition thickness.

Use a compatible gypsum-based jointing compound or adhesive rather than standard cement mortar to prevent shrinkage cracks.
