FRCM with basalt textiles

Repair and strengthening of existing buildings is performed with innovative materials and / or unconventional techniques, as well as FRP (Fibre-Reinforced Polymer). Recently, inorganic matrix–grid composites (FRCM) are spreading for strengthening of masonry structures. Such composites are the result of the coupling of the same fibres used for FRP, with inorganic matrix based on cement mortar or lime mortar. Four different FRCM systems were tested and main parameters were: matrix properties (mortar mixed independently in each laboratory), mortar properties for masonry joints; matrix width and embedded textile cross section and yarn spacing for tensile tests; plus bonded width and masonry width for bond tests; age at testing, test setup, tabs and clamping systems; load rates, transducer types and layouts for data acquisition.
