What is the meaning of special concrete?

What is the meaning of special concrete?

General • Special concretes are the concrete prepared for specific purpose like light weight, high density, fire protection, radiation shielding etc. concrete is a versatile material possessing good compressive strength.

What are the uses of special concrete?

Uses and Application of Special Concrete

• Special concrete is used in extreme weather.
• HPC has been used in large structures such as the Petronas Towers and the Troll Platform.
• Good cohesiveness or sticky in mixes with very high binder content.

Why is special concrete needed in construction?

Strength Strength is the primary reason why concrete has been used by housing developers and construction companies for many decades. Concrete is a solid material that can easily withstand tensile and compressive stresses without getting affected.

What is special type of concrete explain lightweight concrete?

Light Weight Concrete Structural lightweight concrete is similar to normal weight concrete except that it has a lower density. Made with lightweight aggregates. Air-sry density in the range of 1350 to 1850 kg/m3. 28 days compressive strength in excess of 17 Mpa.

What is the role of special concrete in modern construction industry?

Category: Special Concrete in Construction Special concrete are concrete for special purpose for increased strength and durability for various construction applications.

What is a lightweight concrete?

Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. It is being increasingly used to build sleek foundations, and has emerged as a viable alternative to regular concrete.

What are the benefits of using special concrete over normal concrete?

Special concrete makes the structure more durable as compared to normal concrete since special conditions are maintained in preparing such concrete. Special concretes are suitable for extreme weathers and can withstand harsh environmental conditions. Low heat characteristics are observed in special concretes.

What are the types of lightweight concrete?

Types of Lightweight Concrete

• Lightweight Aggregate Concrete : In the manufacturing of the lightweight aggregate concrete care is take that the aggregates used are of light weight.
• No-Fines Concrete : In making of No-fines concrete, fine aggregates are not used.
• Aerated Concrete :

What is Portland cement concrete?

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

Which is a characteristic of a special type of concrete?

Special types of concrete are those with out-of-the-ordinary properties or those produced by unusual techniques. Concrete is by definition a composite material consisting essentially of a binding medium and aggregate particles, and it can take many forms. These concretes do have advantages as well as disadvantages.

What’s the purpose of special concrete in construction?

Special concrete are concrete for special purpose for increased strength and durability for various construction applications.

What’s the difference between ordinary and special concrete?

Difference Between Ordinary and Special Concrete Ordinary Concrete Special Concrete Ordinary concrete is used for normal works like building, bridges, road etc.

What is the syllabus for special concretes?
