Question

It is the kind of concrete to which various fibres of very small diameter (10 to 20 microns) and short lengths (10 to 50mm length) are added to make a concrete. The name of the concrete is

• A. Self compacting concrete
• B. Flyash Concrete
• C. Fibre reinforced concrete
• D. Light weight concrete

Hint:

- Fibre reinforced concrete reduces shrinkage cracks and improves impact resistance.

Answer 1

The Correct Option is C

Step 1: Understanding the definition. - Fibre reinforced concrete (FRC) is a type of concrete with added fibres to enhance tensile strength and durability. Step 2: Properties of Fibre Reinforced Concrete. - Fibres are typically 10-20 microns in diameter and range from 10-50mm in length. - It is used to prevent cracking and improve toughness. Thus, the correct answer is (C) Fibre reinforced concrete.
