Abstract
Abstract This paper analyzes the bond behavior of natural fibers in cement-based matrix. First, it presents the results of pull-out tests carried out on jute fibers embedded in a cementitious mortar. Then, the experimental results are employed in identifying the bond-slip relationship which describes the interaction between fiber and matrix. A theoretical model, capable of simulating the various stages of a pull-out test, is formulated and applied for an inverse identification of the bond-slip law. Finally, the obtained results demonstrate the soundness of the proposed theoretical interpretation for the bond behavior of jute fibers embedded in a cementitious matrix.
