Adobe brick is a building material made from a mixture of clay, sand, and straw, which is shaped into blocks and dried in the sun. This ancient construction method has been used for thousands of years, particularly in arid regions where wood and stone are scarce. The natural ingredients make adobe bricks eco-friendly and sustainable. Once dried, adobe bricks are strong and provide excellent insulation, keeping buildings cool in the heat and warm in the cold. Structures made from adobe are often found in traditional architecture, especially in areas like the American Southwest and parts of Mexico.
