Abstract
This study is part of the valuation of local materials such as clay (earth) and alfa in the region of northern Morocco, with the aim of using them as building brick walls. These materials are abundant natural and renewable. Objective of this work is to study the thermal and mechanical behavior of a new material by mixing the Clay (chosen as linking) with different percentages of mass fiber alfa (0.5, 1, 2, 3, 4%, respectively) and to compare these results with those of material often used in the construction of individual houses in the rural area of Morocco (clay+straw). The results obtained, we will deduct that the incorporation of straw fibers can lower the thermal conductivity compared to fibers alfa which allows to have an energy economy of 2℅ to 7℅., In part against the fibers alfa can improve the mechanical behavior of material to clay base in comparison with the material (clay+ straw) (An increase of 8℅ to 17℅ for the tractive resistance by bending and 6℅ to 18℅ for the resistance to compression).
Highlights
The clay and straw are the two most commonly used materials in the construction of the rural homes of Morocco, because of their abundance and their thermal insulation
By against the fiber alfa contains empty inside which will improve the behavior of thermal material clay based report by the material clay+alfa
We have shown that the increase in the percentages of fibers improves the thermal and mechanical properties of the two samples, provided that the percentage of fiber alfa does not exceed 2%, beyond this values the adhesion
Summary
The clay and straw are the two most commonly used materials in the construction of the rural homes of Morocco, because of their abundance and their thermal insulation. By against the fiber alfa contains empty inside which will improve the behavior of thermal material clay based report by the material clay+alfa. At the basis of these remark of departure it has begun to work on these two materials (clay+alfa and clay+ straw) and to compare Its results thermal and mechanical obtained. Certain studies have already established and published on materials at the root of clay and alfa. Laaroussi et al (2013) have carried out an experimental study of thermal a sample prepared using mixtures of clay bricks
