Updated On: May 27, 2026
- Flue gas
- Fly ash
- Nitrogen oxide
- Sludge
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Fly ash is a fine powder produced from the combustion of pulverized coal in thermal power plants.
Step 1: During coal combustion, ash particles are produced.
Step 2: Fine particles carried with flue gases are collected as fly ash.
Step 3: Fly ash can be used in cement, concrete, bricks, and road construction.
Step 4: Therefore, the coal combustion byproduct useful in construction is: \[ \boxed{\text{Fly ash}} \]
