The ruins of a Han dynasty (202 BCE – 220 CE) Chinese watchtower made of rammed earth in Dunhuang, Province of Gansu, China, at the eastern end of the Silk Road.. Rammed earth is a technique for constructing foundations, floors, and walls using compacted natural raw materials such as earth, chalk, lime, or gravel. [1]
Settler Joseph Steffens built the rammed earth house in 1843; it is the only surviving rammed earth house in the state. Rammed earth construction uses soil to build walls by pressurizing it in molds; the method was common in continental Europe and saw some use in 18th-century eastern America and in the Great Plains and Southwest during the ...

This rammed earth wall is constructed of local soils, concrete, and colour additives. At 80 m (260 ft) long, 5.5 m (18 ft) high, and 0.6 m (2 ft) thick, it is (as of 2014) the largest in North America. Its thickness and mass provide an insulating value of R-33 that help to provide a more stable indoor temperature than the large temperature ...
Based on the literal meaning of the Chinese words tu (土; "earth") and lou (樓; "[tall] building"), one may think of the term "tulou" as a generic description of a rammed-earth building. However, this would not be a useful definition, since, as the scholar of China's traditional architecture Huang Hanmin notes, rammed-earth building of one ...
He was a productive author, producing 72 booklets relating to rammed earth construction, and these writings were translated and widely spread, helping this construction style to flourish. He was also interested in agriculture, being the first author, with Léon de Perthuis de Laillevault in 1805 and 1810, to study rural construction in the ...
Unlike rammed earth construction, only human labor energy is required to tamp the soil lightly. The energy-intensive materials that are used – plastic (for bags & twine), steel wire, and perhaps the outer shell of plaster or stucco – are used in relatively small quantities compared to other types of construction, often totaling less than 5% ...
