an unfired brick made of clay mixed with cut straw or other fibrous materials, such as tow or chaff. One of the most ancient building materials, adobe was widely used in unforested areas; for example, it was used in building the dwellings of Merimde-Benisalame in the Nile Delta in the fifth and fourth millennia B.C. and the defensive wall of Troy II on the coast of Asia Minor in the middle of the third millennium B.C. Adobe is currently used primarily in Asian countries in the construction of low structures.
