Question 1

Is there any special curing requirement for SRC?

Accepted Answer

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

Question 2

What precautions should be taken while using UltraTech SRC Cement?

Accepted Answer

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.

Question 3

Is UltraTech SRC environmentally friendly?

Accepted Answer

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

Question 4

What are the packaging details of this cement?

Accepted Answer

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

Question 5

What is the setting time of UltraTech SRC Cement?

Accepted Answer

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

Question 6

How does UltraTech SRC Cement resist sulfate attacks?

Accepted Answer

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.

Question 7

What are the primary applications of UltraTech SRC Cement?

Accepted Answer

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

Question 8

What are the technical specifications of UltraTech SRC Cement?

Accepted Answer

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.

Question 9

What is UltraTech SRC Cement, and why is it used?

Accepted Answer

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.

Question 10

Can SRC be used in marine construction?

Accepted Answer

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.

Question 11

How does SRC compare to regular Portland cement?

Accepted Answer

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.

Question 12

What are the advantages of using SRC?

Accepted Answer

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.

Question 13

Where can SRC be used?

Accepted Answer

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.

Question 14

What are the key properties of SRC?

Accepted Answer

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.

Question 15

What is UltraTech Sulfate-Resistant Portland Cement (SRC)?

Accepted Answer

UltraTech Sulfate-Resistant Portland Cement (SRC) is a specialized cement designed to resist the damaging effects of sulfate salts in soil and water. It is especially useful in environments where concrete is exposed to high sulfate concentrations, such as foundations and coastal structures, ensuring long-term durability and enhanced performance.
