Building construction technology using clay soil in various forms, already known since ancient times, presents a great potential to regulate indoor humidity, to reduce the indirect impact of construction sector on the environment and on energy consumption. Extensive studies have also been done on the effects of natural fibers on the mechanical and physical behaviour of composite materials in terms of strength, energy efficiency and impact resistance. This work is focused on some natural fiber composites made from different mixtures containing clay soil with different percentages of jute, straw and basalt fibers, in order to determine the ideal mixture between clay and fibers providing the optimum values of thermal inertia, mechanical performance and shrinkage able to improve the energy efficiency of buildings. The mechanical, physical and thermal properties of some specimens have been investigated. The obtained results show an improved mechanical strength and a better thermal conductivity of the clay composite material.

“…Clay soil is one of the most common materials and the socalled adobe bricks made from loam, clay and sand were widely used in the past mostly for housing construction. Still from the Neolithic period, there are evidences of the existence of such constructions in areas like Mesopotamia, Anatolia and the Levant [1].…”

“…The effect of plant fiber addition on the thermophysical proprieties of clay mixtures was investigated by Liuzzi et al [16]. Similarly, Calatan et al [17] remarked that the use of hemp fibers has a positive impact on thermal and mechanical proprieties. Mahamat et al [18] noted that the thermal proprieties of the soil from N'Djamena in Chad without and with straws increase with water content.…”

The thermal performance of exterior walls is considered as a key factor to improving energy efficiency in buildings, especially in areas with cold climates in winter and warm climates in summer. As part of this study, and whose building materials are known for their low thermal properties. The X-ray diffraction was performed on the clay material and the different fibers in order to determine their crystallinity. An experimental characterization of thermophysical properties of a new biocomposites material for the sustainable buildings construction in southern Morocco is presented. These materials can be used as mortar for ceilings and exterior walls. To this end, several samples were prepared from clay extracted from the Errachidia region (south-east Morocco) and three mass fractions of alfa, fig and reed fibers (20%, 40% and 60%). The thermal characterization method adopted is that of the highly insulated thermal house. The results revealed that the incorporation of alfa, fig and reed fibers into the clay matrix allowed a remarkable reduction in apparent density and thermal conductivity. This result shows the interest of using this biocomposite material in construction buildings to ensure thermal comfort and reduce greenhouse gas emissions.

“…Diverse are the properties that have been found to modify in the presence of humidity besides its resistance as it was previously mentioned. To determine the optimum quantity of fiber that has to be added it is necessary to perform a series of experiments that depend on the type of constructed element, for example, in the case of adobe blocks, they must be dosed in quantities less than 40% (Calatan, G. et al 2016). The advantage of adding fibers is that it becomes ecoefficient (Lima, J., &Faria, P. 2016).…”
