The Right answer is Alumina.

Anand said:   6 years ago
Alumina is the right answer. It provides the plasticity to the brick, not the percentage of composition that makes silica the main ingredient.

@All.

They asked which is good quality brick earth, not a major ingredient. So alumina is a correct answer.

Gaurav said:   5 years ago
Silica is the right answer.

Timti said:   5 years ago

Alumina main constituent, silica major constituent.

Nehra said:   5 years ago
Silica is the correct answer because strength is main function of brick.
