Bricks are the only man-made building materials that testify to their use since the early human civilization. With their attractive appearances and superior properties such as high compressive strength and durability, excellent fire and weather resistance, good thermal and sound insulation, bricks are widely used for building, civil engineering work, and landscape design.
