Looking for building materials in india? Here are FAQs on high performance concrete

 

Building materials play an important role in the construction of homes. They determine the strength, durability, and overall quality of the building. This becomes all the more important when you are constructing a high-rise building. High performance concrete is one of the main building materials that is used to ensure that the building is durable and able to withstand the wear and tear that comes with the high volume of people and activity. If you are looking for building materials in India, here are FAQs on high performance concrete that you will find helpful:

 

Question 1: What is high-performance concrete?
High performance concrete is  a type of concrete that has improved mechanical and durability properties, such as high strength, improved resistance to weathering, and greater durability in harsh environments compared to regular concrete.

 

Question 2: What is high-performance concrete used for?

 

High performance concrete is suitable for most internal and external applications such as:

●      High rise buildings

●      Concrete frame structures

●      Marine structures

 

Question 3: What is the difference between high strength concrete and high-performance concrete?

 

●      High strength concrete is a type of concrete that has a higher compressive strength than normal-strength concrete. The compressive strength of normal-strength concrete is typically around 25 MPa (3,500 psi), while the compressive strength of high-strength concrete can range from 40 MPa (5,800 psi) to 100 MPa (14,500 psi) or higher. High-strength concrete is typically made using a lower water-to-cement ratio and specialised admixtures, which increase the strength of the concrete.

 

●      High performance concrete is a type of concrete that has improved mechanical and durability properties compared to normal-strength concrete. It can have high strength like high-strength concrete but also has greater durability, improved resistance to weathering, and a more consistent performance over time. HPC is made with special combinations of cement, fine and coarse aggregate, and chemical admixtures.

 

In general, high performance concrete is designed to meet specific performance requirements and is used in demanding applications. While high-strength concrete is mainly used for applications that require increased compressive strength, such as high-load bearing structures.

 

Question 4: What are the benefits of high performance concrete?

Using high performance concrete  offers the following benefits: .

●      It provides economic benefits through thinner construction elements and reduced construction time.

●      There is higher compressive strength resulting in quality outputs.

●      There is increased elasticity and durability.

●      Low heat generation due to sustainable solutions with increased energy savings.

●      Ease in placement and consolidation without hampering strength.

●      There is a higher seismic resistance compared to conventional concrete.

●      There is higher abrasion resistance

●      The life span of the structure is not affected by severe environments.

●      Superior long-term service performance under static, dynamic and fatigue loading.

 

Question 5: Which cement is best for high performance concrete?

 

A good high performance concrete should have compressive strength of more than 60 MPa, low free lime content, densified cement paste and low bleeding and plastic shrinkage. For instance, Concreto Robuste is a high grade, high performance concrete for 50 to 100 + MPa strength. It is ideal for high rise buildings, columns and concrete frame structures.
