The Percentage content of brick does not make the brick as the main constituent. The only thing that matters is function or role similarly. Alumina plays a major role in brick as mentioned by most of the guys above. So, alumina is the best answer.

Silica is 50 to 60% and more than alumina, but the main constituent is alumina because alumina gives the binding property.

Alumina is the main constituent of clay. It acts as a cementing material in raw brick. Brick clay is plastic due to the presence of alumina. This plasticity ensures that bricks can be molded. An excess amount of alumina in clay may cause the bricks to shrink, warp or crack on drying and burning as any other cementing material.
