الأسمنت البورتلاندي المقاوم للكبريتات (SRC) من (UltraTech Star) بوزن (50Kg)

Key properties of SRC include a low tricalcium aluminate (C3A) content (less than 5%), which minimizes sulfate attack. It also boasts high compressive strength, reduced porosity, and improved resistance to chloride ions, making it suitable for aggressive environments.

SRC is ideal for use in foundations, sewage treatment plants, coastal structures (like seawalls), and any construction exposed to sulfate-rich environments. It is especially beneficial in areas with groundwater or soil containing significant sulfate levels.

The advantages of using SRC include excellent sulfate resistance, high compressive strength, a low heat of hydration (which helps prevent cracking), and enhanced durability of concrete structures under aggressive conditions.

Compared to regular Portland cement, SRC is more durable due to its lower C3A content, which helps it withstand sulfate attacks, making it a superior option for sulfate-prone areas.

Special curing requirements for SRC include curing for a minimum of 8-10 days to ensure optimal strength and durability against sulfate attacks.

While SRC is ideal for sulfate-prone environments, it is not recommended for marine construction where both chlorides and sulfates are present. In such cases, Ordinary Portland Cement with specific C3A levels is preferable to prevent corrosion of reinforcement bars.

UltraTech SRC (Sulfate-Resistant Cement) is a specialized Portland cement designed to resist sulfate attacks, making it ideal for construction in sulfate-rich environments such as coastal areas, basements, and foundations.

It has a compressive strength of approximately 49.4 MPa at 28 days, a density of 3.19 g/cm³, and complies with IS 12330:1988 standards. The tricalcium aluminate (C3A) content is restricted to less than 5%, ensuring high sulfate resistance.

This cement is used in structures exposed to aggressive chemical environments, including sewage treatment plants, marine structures, and water-retaining structures.

The low C3A content minimizes the formation of ettringite and gypsum, which cause expansion and cracking in concrete when exposed to sulfates. This enhances durability in chemically aggressive conditions.

The initial setting time is approximately 150 minutes, while the final setting time is around 275 minutes, ensuring adequate workability during construction.

UltraTech SRC Cement is available in 50kg bags, making it convenient for large-scale construction projects.

Yes, it contributes to sustainable construction by enhancing the durability of structures and reducing maintenance needs over time.

Store the cement in a dry place to prevent moisture contamination. Use appropriate personal protective equipment (PPE) during handling and follow recommended mix designs for optimal performance.
