The Earthen Architecture Association, headquartered in the Czech Republic, is an organization whose members are interested in Earthen Architecture and natural materials, promotes use of clay in new buildings and protection and preservation of existing clay houses as a part of our cultural heritage.
In the ruins of an ancient mud-brick city in northeastern Syria, archaeologists have uncovered what they say is substantial evidence of a fierce battle fought there in about 3500 B.C., which includes the discovery of 120 clay balls that were meant to be fired from slings, as well as 1,200 smaller “bullets.”
A team of MIT architecture students built a wall behind the MIT Museum of rammed earth using a combination of 30 percent Boston Blue Clay mixed with sand and gravel. Twelve tons of this clay, common at depths of 30 to 60 feet in the metropolitan Boston area, came from the excavation site of a new building at Harvard. “The wall will serve as a long-term test of rammed earth in New England, allowing us to observe the way various soil types used in construction stand up to the climate,” said Joe Dahmen, a graduate student in architecture who is leading the project.
