“…Nevertheless, chalky soils are not the only resource used to produce adobe in this heritage area [22], and further studies should be carried out on different specimens from other geological bedrocks, in order to be able to characterize more precisely a greater diversity of local earth resource. Finally, earth can be used as a binder for natural and local insulation, as studied in the CobBauge project [57,58]. As small quantity of raw earth is needed to produce light earth, an investigation on the possibility of producing an insulating material based on local chalky earth could demonstrate new possibility for renovating local heritage and designing low-carbon buildings with a high-quality comfort.…”

Raw earth bricks made from the soil of the Chalky Champagne region (France) have been used for at least two millennia in construction, a promising heritage in the context of reducing the carbon emissions of buildings. The present experimental study aims at measuring the physical, mechanical, thermal, and hydric properties of adobes collected from a local village barn. Results show a high chalk content estimated at 71%, and a clay content, acting as binder, at 14%. Despite limited load-bearing capacity, these lightweight adobes are suitable for current single-story constructions, while their hydrothermal properties classify them as excellent moisture regulators for occupants. In association with other bio-sourced materials such as starch-beet pulp bricks, Chalky Champagne adobes yield promising insulating properties, and meet the criteria defined by current energy standards.

“…Long known earth building techniques (rammed earth, cob, lightened earth, etc. ), have been revisited for a better understanding of their thermal, hygroscopic and mechanical behavior [9][10][11][12][13][14].…”

“…In this project, walls are made up of two layers, namely a structural (cob) and a thermal layer (light earth). Two experimental buildings are under construction, in France (Manche department) and in England (Devon), to assess the site behavior of buildings (housings) using the developed optimal earth / fiber mixtures [14,23].…”
