摘要

This study is part of an approach to valorize local materials, particularly Alfa fibers from northern region of Morocco, in order to using them in sustainable construction. The main goal is to investigate the mechanical performance of a novel material by combining the kaolin clay with various fiber mass fractions, ranging from 0% to 4%. The mechanical properties of the resulting materials were evaluated experimentally and compared with micromechanical models predictions. The results revealed that the addition of Alfa fibers leads to a reduction in compression strength and elastic modulus. Furthermore, a very good concordance was observed between the experimental results and the micromechanical modeling results, with an average relative error not exceeding 6.57%, confirming the relevance of the micromechanical approach used.
