Standard hollow blocks usually measure 400 mm x 200 mm x 200 mm, though variations exist depending on regional standards and specific applications.

The compressive strength of hollow blocks ranges from 3.5 MPa to 7 MPa, depending on the grade and quality. High-strength blocks are used for load-bearing walls.

Hollow blocks provide better thermal insulation compared to solid blocks due to the air gaps within them. This helps in reducing heat transfer and improving energy efficiency in buildings.

Hollow blocks are lightweight, cost-effective, and provide good thermal and sound insulation. They also reduce construction time and allow for easier handling during installation.

Yes, high-strength hollow blocks can be used for load-bearing walls, provided they meet the required compressive strength standards for structural stability.

Hollow blocks use less raw material compared to solid blocks, reducing environmental impact. Additionally, their insulating properties help lower energy consumption in buildings.

The water absorption rate typically ranges from 10% to 20%, depending on the block's composition and quality. Lower absorption rates are preferred for durability in wet conditions.
