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

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.

Warping is the correct answer!

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

I think shrinkage is the answer.

Azeem Khan said:   6 years ago
Correct answer is Shrinkage.

Excess of silica cause brittleness.

Silica or sand (50-60%) in bricks, prevents Shrinkage, Warping and Cracking.

All 3 are Correct.

Warping is due to alumina.

Option (C) is correct.

The amount of silica (sand) present in brick earth is 50-60% and it prevents cracking and warping of raw bricks.
