Study Of The Hydric Behavior Of The Composite In Earth Elaborated With The Local Raw Materials

Abstract Our study aims at developing compatible raw compositions of earth with building materials in the desert zones for an adequate restoration. To arrive at our objective we developed compositions of adobes in bases of the local raw materials red clay of Adrar sand of dune the black sand and the chopped straw. The results of the mineralogical characteristics physical density the humidity and the grading analysis used raw materials showed successful and compatible characteristics with the building materials of the Saharan ksour. The formulations are based on compositions witnesses as reference 1 Volume of clay 2 Volume of sand water. The objective of this study concerns the identification of the various mechanical characteristics mechanical resistance in the flexion and in the compression followed by an ultrasound study mechanism of change in front of hydric behavior of the compatible adobe with the local building materials.
