Product Information

In the 1800s, rammed earth was popularized in the United States by the book Rural Economy by S. W. Johnson. The technique was used to construct the Borough House Plantation [12] and the Church of the Holy Cross [13] in Stateburg, South Carolina, both being National Historic Landmarks. Craterre - This French institute provides training in earth construction techniques and in conjunction with UNESCO seeks to disseminate scientific and technical know-how on earthen architecture. A typical Hmong house-building technique in the subtropical climate of Vietnam. Old rammed-earth wall with deterioration, in France A feature often exploited with rammed earth structures is thermal mass. The thermal mass slows the movement of heat through the walls, then releases the heat when the surrounding temperature drops (at night). Thermal mass structures can even out temperature variations, creating a comfortable internal environment.

Environmental effects and sustainability [ edit ] Rammed-earth trombe wall constructed by Design Build Bluff In modern rammed earth buildings, the walls are constructed on top of conventional footings or a reinforced concrete slab base.A notable example of 21st-century use of rammed earth is the façade of the Nk'Mip Desert Cultural Centre in southern British Columbia, Canada. As of 2014 it is the longest rammed earth wall in North America. [16] 20th century China [ edit ]

Soil mix is poured into the formwork to a depth of 10 to 25cm (4 to 10in) and then compacted to approximately 50% of its original volume. The soil is compacted iteratively, in batches or courses, so as to gradually erect the wall up to the top of the formwork. Tamping was historically manual with a long ramming pole by hand, but modern construction systems can employ pneumatically-powered tampers. Howard, Glenn (1943).

During the Third Front campaign to develop strategic industries in China's rugged interior to prepare for potential invasion by the United States or Soviet Union, Planning Commission Director Li Fuchun project leaders to make do with what was available, including building rammed earth housing so that more resources could be directed to production. [19] :207 This policy came to be expressed through the slogan, "First build the factory and afterward housing."

Rammed-earth walls form part of the entrance edifice of the Eden Project in Cornwall, England, UK See also [ edit ] Mixing cement with the soil can counteract sustainable benefits such as low embodied energy because manufacture of the cement itself creates 1.25 tonnes of carbon dioxide per tonne of cement produced. [9] Although it has low greenhouse gas emissions in theory, transportation and the production of cement can add significantly [ quantify] to the overall emissions of modern rammed earth construction. The most basic kind of traditional rammed earth has very low greenhouse gas emissions but the more engineered and processed variant of rammed earth has the potential for significant emissions. [ citation needed] History [ edit ] A hangtu section of the Great Wall of China Rammed-earth edifice on a farm in FranceRammed earth construction was both practically and ideologically important during the rapid construction of the Daqing oil field and the related development of Daqing. [17] :55 The "Daqing Spirit" represented deep personal commitment in pursuing national goals, self-sufficient and frugal living, and urban-rural integrated land use. [18] :3 Daqing's urban-rural landscape was said to embody the ideal communist society described by Karl Marx because it eliminated (1) the gap between town and country, (2) the gap between workers and peasants, and (3) the gap between manual and mental labor.

[6] [15] Edifices formed of rammed earth are on every continent except Antarctica, in a range of environments including temperate, wet, [3] semiarid desert, montane, and tropical regions. The availability of suitable soil and a building design appropriate for local climatic conditions are the factors that favour its use. Making rammed earth involves compacting a damp mixture of subsoil that has suitable proportions of sand, gravel, clay, silt and stabilizer, if any, into a formwork (an externally supported frame or mold).Betts, Morris Cotgrave; Miller, Thomas Arrington Huntington (May 1937) [1925].

Edifices of rammed earth are more sustainable and environmentally friendly than other building techniques that use more cement and other chemicals. Because rammed-earth edifices use locally available materials, they usually have low embodied energy and generate very little waste. [ citation needed] The soils used are typically subsoil which conserve the topsoil for agriculture. When the soil excavated in preparation for a foundation can be used, the cost and energy consumption of transportation are minimal. [8] Rammed earth is probably the least environmentally detrimental construction material and technique that is readily and commercially available today to construct solid edifices. [ citation needed] Rammed earth has potentially low manufacturing impact, contingent on the amount of cement and the amount that is locally sourced; it is often quarried aggregates rather than "earth".
