Baked-mud brick, also known as ADOBE, is a building material made from mud and straw that has been dried in the sun. It is an ancient construction technique that has been used for centuries in many parts of the world. ADOBE bricks are durable, fire-resistant, and relatively inexpensive to make. They are also environmentally friendly, as they require no energy to produce. ADOBE bricks are commonly used in the construction of homes, walls, and other structures.
