Experimental tests for the characterization of sisal fiber reinforced cementitious matrix for strengthening masonry structures
Highlights Characterization of innovative FRCM with natural fibers is performed. Sisal-NFRCM performances are investigated through tensile and shear tests. Dispositions of the Round Robin Tests RILEM Technical Committee 250-CSM are adopted. Tensile tests evidenced an appreciable tension stiffening effect. Single-lap shear tests evidenced the failure of the yarns with progressive slippage.
Abstract The experimental characterization of a Natural Fiber Reinforced Cementitious Matrix (NFRCM), made of sisal fibers yarns impregnated with a water-based resin and embedded in an inorganic matrix based on natural lime is presented in this paper. The Sisal-NFRCM performances are investigated through tensile and single-lap shear tests, adopting the dispositions of the Round Robin Tests developed for the FRCM characterization by the RILEM Technical Committee 250-CSM. The tensile stress-strain curve evidenced the tension stiffening effect of the mortar between cracks, which tended progressively to reduce. In shear tests, the failure and the progressive slippage of the sisal yarns was observed.
