Abstract

The present work aims to investigate experimentally and analytically the mechanical behavior of a new and ecological material based on clay reinforced with different mass percentages of short Alfa fiber (0%, 1%, 2%, 3%, and 4%). The characterization was carried out by X-ray diffraction (XRD), X-ray fluorescence (XRF), and infrared spectroscopy, as well as by microscopic observations using scanning electron microscopy (SEM). The results indicated that the clay consists of a significant proportion of kaolinite, quartz, and muscovite. Moreover, the addition of Alfa fibers to the clay resulted in a decrease in compression strength. This trend is justified by the length of fibers, which is insufficient to prevent the propagation of cracks. Also, this decrease can be attributed to porosity, where samples with higher fiber content induce more voids that were entrapped during the mixing process. On the other hand, the reinforced samples resist beyond the breaking load. Indeed, this resistance is due to the transfer of internal forces from the matrix to the fibers.
