Date and doum palm natural fibers as renewable resource for improving interface damage of cement composites materials

Abstract Background Various recent studies have investigated the use of traditional fibers (metallic or synthetic) as reinforcement in mortar. In times, there has been growing interest using natural cement composites. This study was conducted to assess impact date palm, doum and sisal on mechanical properties Genetic modeling chosen find shear damage at fiber-matrix interface three composites genetic crossing operator, which allows us calculate two damages matrix fibers, respectively. Results Our objective is examine evaluate palm/mortar, palm/mortar sisal/mortar under different tensile stresses ranging from 25 37 MPa with fiber volume fraction 1 5%. It found that minimal compared sisal/mortar. However, several researchers an increase leads decrease density what we confirmed this increases when increases. Conclusions The results are line findings a experimental other plant fibers. Their showed incorporating ramie resulted 27% compressive strength, whereas synthetic 4% strength compression. recommended palm composition mortars 5% order reduce avoid limit negative environment.
