BIS CERTIFICATION for Concrete Masonry Units - Autoclaved Cellular Aerated Concrete Blocks IS 2185 (Part 3)

Published Date: September 21, 2024

Introduction

Made to IS: 2185 (Part 3):1984 specifications, autoclaved cellular aerated concrete AAC blocks constitute a complete revolution in construction materials that are both environment-friendly and economical alternatives to conventional building blocks. This is a block that has been manufactured after proper steam curing and autoclaving at high temperatures. They assure good strength, with a specific density low enough to be used as a strong insulation material. BIS certification is required because these blocks have to ensure compliance with the most stringent parameters of quality and safety.

BIS certification is required because these blocks have to ensure compliance with the most stringent parameters of quality and safety. This not only opens up access to the Indian market, wherein sales of building materials are not permitted if they do not carry BIS certification but also confirms compliance with IS 2185 (Part 3):1984, thereby establishing credibility for the product and confidence in customers' minds. It further helps MSMEs gain entry into and expand in the market based on demonstrated quality of products. AAC blocks are becoming popular in India these days due to the many conveniences they offer against conventional materials. They offer thermal insulation better than conventional materials, optimum acoustic performance with better fire resistance. They are light and thus easy to manipulate and construct as well. These qualities make them popular for both new construction as well as renovation works.

End uses:

Lightweight Design:AAC blocks reduce the load on structural elements, making them ideal for various construction applications.
Thermal Insulation: Their excellent thermal properties enhance energy efficiency in residential, commercial, and industrial buildings.
Versatile Applications:Commonly used for partition walls, load-bearing walls, and external cladding.

Overview of IS 2185 (Part 3):1984

IS 2185 (Part 3):1984 is an Indian Standard that specifies the requirements for Autoclaved Cellular Aerated Concrete (AAC) blocks used in construction. This standard outlines the dimensions, physical properties, and testing methods for AAC blocks, ensuring their suitability for various building applications. AAC blocks are lightweight, provide excellent thermal insulation, and are fire-resistant, making them a preferred choice in modern construction. The standard ensures that these blocks meet stringent quality and safety criteria, facilitating their use in both residential and commercial projects. Compliance with IS 2185 (Part 3):1984 is mandatory for market approval and certification in India.

Key Aspects of IS 2185 (Part 3):1984

Material Specifications: Defines the composition, density, and physical characteristics of AAC blocks to ensure quality and durability.
Performance Requirements: Establishes criteria for load-bearing capacity, thermal insulation, sound insulation, and moisture resistance.
Safety Needs: Addresses fire resistance, structural stability, and environmental impact to ensure safe usage in construction.
Testing and Compliance: Outlines methods for testing mechanical properties, dimensional accuracy, and durability to ensure compliance with standards.
