Question 1

What is Sulfate-Resistant Portland Cement (SRC) used for?

Accepted Answer

Sulfate-Resistant Portland Cement (SRC) is used in environments where concrete is exposed to sulfates, such as in sewage treatment plants, coastal areas, and structures on reclaimed ground. It provides durability against sulfate attacks, which can cause concrete deterioration. SRC is also suitable for use in marine constructions and areas with high sulfate concentrations in soil or water.

Question 2

What are the key applications of SRC?

Accepted Answer

Key applications of SRC include concrete structures in sewage treatment works, substructures on reclaimed ground, marine constructions, and areas with high sulfate concentrations. It is also used in foundations, basements, and underground structures where sulfate exposure is a concern.

Question 3

What standards does National SRC comply with?

Accepted Answer

National SRC complies with international standards such as BS 4027:1996 and ASTM C-150 Type V. These standards ensure the cement meets specific requirements for sulfate resistance and strength.

Question 4

What is the typical packaging of National SRC?

Accepted Answer

National SRC is typically packaged in 50 kg bags. This packaging is convenient for handling and storage in construction sites.

Question 5

How does SRC improve concrete durability?

Accepted Answer

SRC improves concrete durability by limiting the chemical reaction between the tri-calcium aluminate (C3A) in the cement and sulfate ions in the environment. This reduces the risk of concrete expansion and cracking, thereby enhancing the lifespan of structures.

Question 6

What are the recommended storage conditions for SRC?

Accepted Answer

SRC should be stored in a dry environment to prevent premature hydration and carbonation. Moisture can significantly deteriorate the quality of the cement.

Question 7

What factors affect the strength development of SRC-based concrete?

Accepted Answer

The strength development of SRC-based concrete is affected by factors such as the water/cement ratio, curing conditions, ambient temperature, and the properties of the mix constituents. Optimal strength is achieved with a low water/cement ratio and proper curing.

Question 8

What is the typical strength of SRC mortar prisms?

Accepted Answer

Typical mortar prism strengths for SRC can range from 50-60 MPa at 28 days, with about 70% of this strength achieved at 7 days. This strength is significantly influenced by the mix design and curing conditions.
