Which of the following ingredients of the brick earth enables the brick to retain its shape?

Solution(By Examveda Team)

The ingredient of brick earth that enables the brick to retain its shape is silica. Silica is one of the primary components of brick clay. It is responsible for the cohesion and binding properties of the clay when it is molded into bricks and then fired. Silica melts at a high temperature, which helps in fusing the clay particles together during the firing process, resulting in a solid and durable brick. Therefore, silica content is crucial in determining the quality and strength of bricks.
