Question

The most commonly used material in modern construction for making beams and columns is:

• A. Steel
• B. Aluminum
• C. Concrete
• D. Wood

Hint:

Concrete is the most commonly used material in modern construction due to its cost-effectiveness, compressive strength, and adaptability in molding shapes.

Answer 1

The Correct Option is C

Step 1: Material selection in construction
In modern construction, the choice of materials for beams and columns is crucial for the stability, strength, and longevity of structures. Concrete is the most commonly used material because of its versatility, cost-effectiveness, and ability to withstand compression.
Step 2: Benefits of concrete
Concrete has high compressive strength and can be easily molded into various shapes. It is also durable and resistant to fire, making it the preferred material for large-scale constructions, including beams and columns in buildings, bridges, and other infrastructure.
Step 3: Comparison with other materials
Although steel and aluminum are used in some specialized applications, concrete is more commonly used for the structural elements in construction due to its availability, strength, and ease of construction.
