Correct answer is Shrinkage.

Excess of silica cause brittleness.

I think shrinkage is the answer.

The shape of brick is depend on silica so prevent warping of the brick.

Warping is the correct answer!

Good quality bricks contain 50-60% silica. Silica prevents raw bricks from cracking, shrinking and warping. The higher the proportion of sand, the more and shapely and uniform in texture will be the brick. Although, excess silica destroys cohesion between the brick clay particles and makes brick brittle and weak.

As per my knowledge, silica prevents cracking, warping and shrinkage.
