In structural applications, what is a potential drawback of using High Performance Concrete?

Explanation:

• HPC has a high workability and stiffness, making it more resistant to compaction during placement.
• Its dense mix can lead to challenges in achieving proper compaction, especially in intricate formwork or congested areas, which could result in voids and reduced performance.

 Additional Information

HPC is a type of concrete that has superior properties, such as higher strength, durability, and workability compared to conventional concrete. It is designed to perform well in demanding conditions, such as extreme weather or exposure to chemicals.

Key Features:

• High Strength: HPC typically offers much higher compressive strength than conventional concrete.

• Enhanced Durability: It is resistant to aggressive environmental factors like chemical attacks, freeze-thaw cycles, and abrasion.

• Workability: Although highly workable, its high stiffness can pose challenges during compaction, especially in tight spaces.

• Improved Bonding: It provides strong adhesion with reinforcement, reducing the risk of cracks.
