Super
Sulphated Cement is a specialized cement designed for use in environments with
high sulphate exposure. With a unique composition of granulated blast furnace
slag, gypsum, and a small amount of clinker, this cement offers enhanced
resistance to sulphate attack, making it ideal for constructions like
foundations, underground structures, and wastewater treatment facilities. Super
Sulphated Cement is particularly valued for its durability and low heat of
hydration, which reduce thermal cracking in mass concrete pours. Its
specialized properties make it an essential choice for infrastructure projects
in aggressive soil conditions.
Introduction
In
response to increasing demands for quality assurance, the Ministry of Commerce
and Industry, through the Department for Promotion of Industry and Internal
Trade (DPIIT), issued the Cement (Quality Control) Order, 2023. Effective from
January 1, 2024, this regulation requires BIS certification for Super Sulphated
Cement as per Indian Standard IS 6909:1990. The BIS certification, marked by
the ISI symbol, is mandatory before these cements can be marketed in India.
Ensuring consistent performance and safety, this certification supports uniform
standards and safeguards constructions exposed to sulphate-rich environments.
Why is BIS Certification Necessary for Super
Sulphated Cement?
BIS
certification is essential for Super Sulphated Cement as it enforces strict
quality guidelines, crucial for applications in high-sulphate conditions. IS
6909:1990 ensures that Super Sulphated Cement meets specific criteria, such as sulphate
resistance, compressive strength, and low heat of hydration. This minimizes
risks of structural damage due to sulphate attacks, enhancing the longevity of
constructions in aggressive soils. BIS certification under the Cement (Quality
Control) Order, 2023, also ensures compliance with Indian safety regulations,
providing consumer trust in certified products while fulfilling legal
requirements under the Bureau of Indian Standards Act, 2016.
Overview of Indian Standard IS 6909:1990
Indian Standard IS 6909:1990 specifies the essential
requirements for Super
Sulphated Cement, ensuring its suitability for use in
aggressive environments, particularly those prone to sulphate attacks. The
standard emphasizes sulphate
resistance, making SSC ideal for applications in sulphate-rich
soils or seawater, where conventional cements might fail. It also ensures that
the cement delivers adequate compressive
strength, providing reliable structural support in high-stress
applications. Additionally, SSC has a low
heat of hydration, which helps minimize the risk of thermal cracking in
large concrete structures. The standard prescribes setting times to ensure
proper handling and application, allowing for efficient construction processes.
Fineness
and uniformity
are also controlled to ensure consistent quality and performance across all
batches of cement. Compliance with IS
6909:1990 is crucial for manufacturers to produce Super Sulphated Cement
that maintains its durability and performance even in the most challenging
environmental conditions, ensuring the longevity and safety of structures
exposed to aggressive chemical environments.
Process for BIS Certification
The BIS
certification process for Super Sulphated Cement includes the following steps:
Documents Required for BIS Certification
The
following documents are generally required for BIS certification of Super
Sulphated Cement:
Additional documents may be required based on the specific product and regulatory compliance requirements.
Conclusion
BIS
certification for Super Sulphated Cement is essential to maintain product
quality and safety under IS 6909:1990, particularly for infrastructure exposed
to sulphate-rich soils. Complying with the Cement (Quality Control) Order,
2023, ensures that manufacturers provide durable, high-performance cement that
meets critical standards in the Indian market.
