Bricks are rectangular blocks made from clay or other materials that are hardened by heat. They are commonly used in construction for building walls, pavements, and other structures. Bricks are created by molding the raw material into shape and then firing it in a kiln at high temperatures to achieve strength and durability. There are various types of bricks, including clay bricks, concrete bricks, and firebricks, each suited for different building requirements. Bricks are known for their strength, fire resistance, and ability to provide insulation.
