Alumina main constituent, silica major constituent.

Silica is the correct answer because strength is main function of brick.

Vinod sharma said:   4 years ago
Silica is the main constituent of brick.

WASEEM SANGI said:   4 years ago
Silica is right as its amounts 50-60%.

Ravindra Bhalerao said:   9 years ago
It should be silica.

Yes silica has more percent (50-60) and alumina has (20-30) but the main ingredient for its good quality is Alumina. So, the answer must be D.

Ravi said:   9 years ago
The right answer is Silica.

Dileepan said:   9 years ago
Alumina 20-30 percentage is correct because its absorb water and imparts plasticity to the clay and makes brick hard.

Sndip said:   9 years ago
Silica is the right answer.

Major constituent is Alumina not silica. No matter what is percentage is. Alumina provides plasticity to bricks.
