“…For the tested materials (kaolin mortar and cob earth), it appears that there is a relationship between the reinforcement effect of the woven fabric and the height of an elemental layer of earth-based material between woven fabric sheets. These results are in agreement with results previously obtained in the work of P'kla [35,36] and more generally with works on the reinforcement of soils by geotextiles and geomembranes [37,38].…”

Earth-based mortars are commonly reinforced with bio-based materials such as straw or biopolymers. The aim of this work is to identify reinforcements that are able to improve the mechanical strengths and the ductility of an earth-based matrix. We have also attempted to describe the mechanisms of reinforcement involved in such materials. Firstly, a kaolinite-based clay soil was mixed with sand to achieve earth-based mortars with the highest density at the dry state. For this material (kaolinite-based mortar), we have shown that, at the same water content, the compressive strength at the dry state only depends on the dry density of the sample whatever the forming process. Various quantities of fibers, fabrics and alginate were then used to reinforce the studied mortars (a kaolinite based mortar and a natural soil containing swelling clay sieved at 4 mm). We found that these reinforcements significantly increase the compressive strength of all tested samples containing kaolinite. A comparison between the two materials helps us to understand the reinforcement mechanisms for various fibers; it also demonstrates that natural fibers and woven fabrics enhance the mechanical behavior of earth mortars notably under a compressive load.

“…Fortunately air lime-based mortars regained interest in the last couple of decades and have been studied by several researchers (Andrejkovicová et al 2013, Coroado et al 2010, Arizzi et al 2012. Meanwhile earth mortars have only been systematically studied by few researchers (Azeredo et al 2008, Minke 2011, Stazi 2003, Pkla et al 2003 and stabilised earth mortars with little amount of air lime have also been studied by very few researchers (Fernandes et al 2012, Gomes et al 2012a. In this last study, mortars were formulated and characterised with a commercial earth.…”
