BIS Certification for Concrete Masonry Units – Hollow and Solid Lightweight Concrete Blocks (IS 2185 Part 2)

Introduction

IS 2185 (Part 2):1983 defines the basic requirements for making lightweight concrete blocks, both hollow and solid, used in structural and non-structural parts of buildings. This standard ensures that such blocks meet strict quality and performance benchmarks set by BIS. Getting BIS certification under this standard helps manufacturers prove that their products are durable and strong. It also improves the market value of these blocks while giving builders and customers confidence that the materials used in construction are reliable and effective.

Lightweight concrete blocks must be BIS certified to ensure that they meet the quality and performance standards set by the Bureau of Indian Standards. Certification confirms that the blocks are strong, durable, safe, and compliant with all regulatory requirements. In construction projects, this means only materials that meet high safety and quality standards are used, ensuring structural integrity. For builders and contractors, BIS-certified blocks provide reliability and reduce risks on-site.

With rapid urbanisation and a growing focus on environmental sustainability, the demand for lightweight concrete blocks in India has increased significantly. These blocks are preferred because they save energy and have less impact on the environment, supporting eco-friendly construction practices. Consistency in quality and performance not only ensures safety but also helps in completing projects on time. BIS certification adds credibility to the blocks, giving builders and contractors more confidence and making them a stronger choice in the competitive construction market.

End Uses:

• Structural Applications: Used in load-bearing walls, offering strength and stability for different building types.

• Non-Load Bearing Walls: Ideal for partitions and interior walls, providing good thermal and sound insulation.

• Architectural Finishes: Suitable for facades and decorative purposes, adding aesthetic appeal while ensuring durability.
