Experimental tests for the characterization of sisal fiber reinforced cementitious matrix for strengthening masonry structures
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. ; The authors acknowledge Fibre Net SpA (Pavia di Udine, Italy), the Construction science laboratory of the University IUAV of Venice (Labsco) and the Laboratory of Testing Materials of the University of Trieste for the support given at these experimental tests. This work was partly financed by the research project PRIN 2015 (under grant 20151W9NJT_014, project "Advanced mechanical modeling of new materials and structures for the solution of 2020 Horizon challenges") and FEDER funds through the Competitively Factors Operational Programme - COMPETE and by national funds through FCT - Foundation for Science and Technology within the scope of projects POCI-01-0145-FEDE-007633.
