As part of the recovery of local materials in arid and semi-arid areas, the adobe will be chosen as a reductive object. This research topic consists of the use of clay for construction. The latter is abundant in the south of Algeria and has properties that appear to be suitable for building design. The purpose of this project is to evaluate the behaviour of clay-based Adobe by adding dune sand, gravel 8/15 and gravel 3/8 by different percentages. This technical study is based on the application of tests for the physical and mechanical characterization of the latter.This study is launched with the aim of characterizing a clay based on local materials from the Ouargla region, namely Baldat Amor clay, sand from the dune of Sidi khouiled, gravel from Ouargla.

This research is oriented towards the valorisation of local materials and the reduction of energy consumption with the aim of judicious use of these materials. In front of the world economic crisis, that also affects our region, it is necessary to solve the problem of pollution and enable important links for the balance with nature. In Algeria, buildings are very inefficient in terms of energy use and therefore remain a major source of energy consumption. To reduce this consumption and improve the thermal comfort of a building and save energy, it is necessary to use particularly high-performance materials that ensure good thermal insulation. The objective set in this work is to study the thermal behaviour of walls of different compositions, in order to identify those that allow the greatest energy savings in the case of air-conditioning for the Saharan context. The results proved that it is possible to use local materials to reduce energy consumption by 50% and save energy, improve the performance of the construction, and ensure the thermal comfort of buildings.
