Résumé
In rural Algeria, demand for housing exceeds supply, despite government policies to restore and build. The quality of some new housing is questioned, in part because of the use of expensive manufactured building materials and standard plans. Some experts have suggested that earth - widely available, cheap, and used for traditional housing - should be used for the construction of new houses. Earth material used traditionally had advantages, but drawbacks, mainly in its mechanical and physical properties. These drawbacks can be minimised by appropriate design, and improvement of the intrinsic qualities of earth, particularly strength and durability, through stabilisation, i.e. the addition of an adjuvant and/or the compression of particles that constitute the material. However, despite the claimed improvement of qualities of soil used, the few contemporary earth-built schemes in rural Algeria had a number of problems, particularly deficiencies in strength and durability. In this study, these problems were investigated, using a case study approach. Four potential problem areas - laboratory testing, structure and construction process, design process, and involvement of users in building and subsequent maintenance and repair of their dwellings - were identified and investigated in housing schemes built with improved earth material in Mostefa Ben Brahim, Sidi-Bel-Abbes, in Algeria. The main research findings were that laboratory tests and analyses did not necessarily predict the practical performance of material used. However, correction can increase the cost of soil, so diminishing its cost advantage, and neither of the accepted strength and durability tests on stabilised soil specimens tell exactly how long a soil block lasts : they help only in deciding between several soils
