FRCM-confined masonry columns: experimental investigation on the effect of the inorganic matrix properties

The present paper reports and analyses the experimental results on FRCM-confined masonry columns subjected to centred compression test. The main goal of this research consists in evaluating the role of the inorganic matrix in determining the effectiveness of FRCM-confinement. For this purpose, three different inorganic matrices, having different compressive strength, have been considered and used for confining a poor-quality masonry column. The different increases of the axial strength, due to the differences of the compressive strength of the matrices of the FRCM-system, have been assessed. Finally, the experimental results have been compared with the theoretical predictions obtained from the application of an analytical model, available in the literature.
