ABSTRACT
The world's willingness to reduce the ecological footprint of construction materials is the main engine of the development and reuse of earth-based materials. With its availability, low cost, and simplicity of implementation, the rammed earth material presents a good alternative for ecological construction. However, this material remains less resistant than conventional construction materials, especially cement-based ones. To enhance the mechanical characteristics of rammed earth, several stabilization and reinforcement techniques were adopted. Among these techniques, the use of natural fibers shows an increasing trend. This review is based on studies carried out on the reinforcement of rammed earth with natural fibers. The types of fibers used, their treatment methods, and their physical and mechanical properties are presented. The impact of natural fiber reinforcement on the physical and mechanical properties of rammed earth is also reviewed and discussed. The results of the studies carried out, prove the effectiveness of the fiber reinforcement technique. Indeed, an increase in the compressive, flexural, and tensile strengths of the rammed earth was reported. This improvement depends on the type of fibers used, their contents, and their dimensions. At the end of the study, perspectives for future research are given, especially regarding the durability of the reinforced rammed earth and the impact of the fiber reinforcement on its hygrothermal properties. To improve the adhesion strength between the fibers and the earth matrix, the use of chemically treated fibers for reinforcement is suggested.
