Focusing sustainable development, which of the following construction materials is increasingly being used in Gujarat’s new infrastructure projects?
- ATraditional lime plaster
- BFly ash bricksCorrect
- CBamboo
- DRecycled plastic
Solution
Concept
Sustainable construction using fly ash bricks
Formula
NONE
Step-by-step solution
1. Fly ash is an industrial byproduct whose utilization in construction reduces land pollution and carbon footprint. 2. Fly ash bricks provide high strength, uniform dimensions, and enhanced thermal performance over clay bricks. 3. Consequently, fly ash bricks are increasingly adopted in sustainable infrastructure projects across Gujarat. Answer: B
Explanation
Fly ash bricks utilize fly ash, an industrial byproduct from thermal power plants, making them a sustainable alternative to traditional fired clay bricks. Using fly ash conserves fertile agricultural soil, reduces industrial waste, and lowers overall carbon emissions during production. As a result, fly ash bricks are increasingly used in modern infrastructure projects, making option B correct.
Why the other options are wrong
A) Traditional lime plaster is an ancient finishing material rather than a modern sustainable structural component. C) Bamboo is limited in large-scale modern infrastructure projects compared to fly ash bricks. D) Recycled plastic is not yet as widely adopted for structural infrastructure as fly ash bricks.
Shortcut
Sustainable modern construction material = Fly Ash Bricks.
Common mistake
Selecting Option D (Recycled plastic) or Option C (Bamboo) by confusing general eco-friendly materials with standard fly ash brick usage.
Correct answer: B) Fly ash bricks
