Effect of Fiber Alfa on Thermophysical Characteristics of a Material based on Clay

This work is part of the development of local materials such as clay and fiber alfa in the north of Morocco. These materials are abounding, natural and renewable, they have thermal properties very interesting. Our objective is to study the fiber alfa effect on the thermal characteristics of clay based materials. For this reason we mix the clay (chosen as base material) with different percentages of fibers alfa (0.5%, 1%, 2%, 3%, 4%).Then we compare the properties thermo physical of this new material with those of clay only, to motivate the proposal to use this material as insulation in rural construction. This comparison of the energy performance of these two materials will enable us to deduce that the new material is less effusif than clay alone, its lightness exceeds that of clay only, and its use as brick walls should give an energy saving over 30%.
