Elevate Construction Standards with IS 2185 Part 3:1984-Certified AAC Blocks

In today’s fast-evolving construction industry, quality, safety, and sustainability are no longer optional—they are the very foundation of progress. Among modern building materials, Autoclaved Aerated Concrete (AAC) blocks have emerged as a preferred choice due to their lightweight, eco-friendly, and high-performance characteristics. But not all BIS for AAC Blocks are created equal. To ensure reliability and compliance, certification under IS 2185 Part 3:1984 by the Bureau of Indian Standards (BIS) is mandatory.

At EVTL India, we guide manufacturers and suppliers in achieving this crucial certification, helping them build credibility in the market and contribute to safer, stronger, and greener construction.

What Are AAC Blocks and Why Do They Matter?

AAC blocks are precast, foam concrete building materials made from cement, lime, sand, water, and an aerating agent. They are manufactured through a high-pressure autoclaving process that gives them a porous structure. This unique composition makes BIS Certification for AAC Blocks  Lightweight – About one-third the weight of traditional clay bricks, reducing structural load.

• Thermally Efficient – Excellent insulation keeps interiors cooler in summer and warmer in winter.
• Fire Resistant – AAC blocks can withstand high temperatures, adding a layer of safety to buildings.
• Environmentally Friendly – Made from non-toxic, recyclable materials with lower energy consumption during production.

Because of these features, AAC blocks are increasingly replacing conventional bricks in residential, commercial, and industrial projects. However, to ensure that these blocks truly meet performance expectations, ISI marking through BIS certification is essential.

Understanding IS 2185 Part 3:1984

The Indian Standard IS 2185 Part 3:1984 lays down the specifications for AAC blocks, including:

• Dimensions & Tolerances – Ensuring uniformity in size for seamless construction.
• Density Requirements – Regulating block density for strength and insulation balance.
• Compressive Strength – Minimum strength criteria to support load-bearing capacity.
• Drying Shrinkage – Limits to prevent cracks and structural instability.
• Moisture Content – Standards for durability and weather resistance.

Compliance with these requirements means the AAC blocks are not only structurally sound but also reliable for long-term use.

Why ISI Certification Matters for AAC Blocks

1. Market Trust and Acceptance Buyers, architects, and builders prefer certified AAC blocks, knowing they comply with BIS standards. ISI marking instantly builds credibility.
2. Legal and Regulatory Compliance In India, certain products cannot be sold without BIS certification. For AAC blocks, IS 2185 Part 3:1984 compliance is mandatory to avoid penalties and market restrictions.
3. Enhanced Quality Assurance Certification guarantees that every batch of AAC blocks undergoes testing for strength, durability, and performance.
4. Competitive Edge ISI certification distinguishes your brand in a competitive market, allowing you to cater to government projects, large-scale builders, and infrastructure contracts.
