Silica is the right answer.

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.

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.

Silica is the right answer.

Gajan Rana said:   9 years ago
Major constituent is Alumina not silica. No matter what is percentage is. Alumina provides plasticity to bricks.

Silica is the right answer.

Rajesh thakur said:   9 years ago
The major role in bricks composition is done by aluminium because it provides plasticity none of the other compounds can do so.

KARAN said:   9 years ago
Obviously, Silica is the major constituent of Brick so 'C" is the best answer.

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