The use of Natural Fibers (NFs) in Fiber-Reinforced Cementitious Composites (FRCCs) is an innovative technical solution, which has been recently employed also in High-Performance FRCCs. However, NFs are generally characterized by complex microstructure and significant heterogeneity, which influence their interaction with cementitious matrices, whose identification requires further advances in the current state of knowledge. This paper presents the results of pull-out tests carried out on sisal fibers embedded in a cementitious mortar. These results are considered for identifying the bond-slip law that describes the interaction between the sisal fibers and the cementitious matrix. A theoretical model, capable of simulating the various stages of a pull-out test, is employed as part of an inverse identification procedure of the bond-slip law. The accuracy of the resulting simulations demonstrates the soundness of the proposed theoretical model for sisal fibers embedded in a cementitious matrix.

The study is part of SUPERCONCRETE Project (H2020-MSCA-RISE-2014, n. 645704): the Authors wish to acknowledge the financial contribution of the EU-funded Horizon 2020 Programme. More specifically, it was partly developed during the mobilities of both Prof. Romildo D. Toledo Filho at the University of Salerno (Italy), and Dr. Marco Pepe at the Federal University of Rio de Janeiro (Brazil).
