Mud-brick is a building material made from a mixture of clay, sand, and water, which is then shaped into bricks and dried in the sun. This ancient construction method has been used for thousands of years, particularly in regions with limited access to timber. Mud-bricks are known for their thermal properties, helping to keep buildings cool in hot climates. The use of mud-brick can be traced back to early civilizations, including the Mesopotamians and Egyptians. Structures made from mud-brick are often found in archaeological sites, showcasing their durability and effectiveness as a building material. Today, mud-brick is still used in sustainable architecture, promoting eco-friendly construction practices.
