“…Basalt fibres may be used separately as microfibers, successfully fulfilling the function of a reinforcing agent in composite materials based on inorganic matrices [4,5,6,7], or as a reinforcement element in the form of a surface fabric, the use of which appears to be very effective [1,8]. In addition, basalt fibres arranged in the form of a surface fabric have been successfully used in the past, for example in reinforcing concrete beams [9], historical pillars [10] or surface panels [1,11,12]. In all of the mentioned cases, basalt fibres, whether as single fibres, fibre bundles or fibre lattices, function as a reinforcement element in a matrix made of concrete, mortar or other material.…”

The development of composite materials from alternative raw materials, and the design of their properties for the intended purpose is an integral part of the rational management of raw materials and waste recycling. The submitted paper comprehensively assesses the physical and mechanical properties of sandwich composite material made from particles of winter rapeseed stalks, geopolymer and reinforcing basalt lattices. The developed composite panel is designed for use as a filler in constructions (building or building joinery). The observed properties were: bending characteristics, internal bonding, thermal conductivity coefficient and combustion characteristics. The results showed that the density of the particleboard has a significant effect on the resulting mechanical properties of the entire sandwich panel. On the contrary, the density of the second layer of the sandwich panel, geopolymer, did not have the same influence on its mechanical properties as the density of the particleboard. The basalt fibre reinforcement lattice positively affected the mechanical properties of sandwich composites only if it was sufficiently embedded in the structure of the particle board. All of the manufactured sandwich composites resisted flame for more than 13 min and the fire resistance was positively affected by the density of the geopolymer layer.

“…Various studies have demonstrated the effectiveness of the FRCM in strengthening URM structures, such as FRCM-confined masonry columns (Cascardi et al, 2018;Fossetti and Minafo`, 2017;Krevaikas, 2019;Mezrea et al, 2017), FRCM-strengthened URM walls under in-plane and out-of-plane actions (Augenti et al, 2011;Babaeidarabad et al, 2015;Ismail et al, 2018;Marcari et al, 2017;Papanicolaou et al, 2008;Parisi et al, 2013;Prota et al, 2006;Sagar et al, 2017), and FRCM-strengthened arches and vaults (Carozzi et al, 2018;Garmendia et al, 2015;Giamundo et al, 2015;Ramaglia et al, 2016). These investigations indicated that the carrying and deformation capacities of URM structures or members are effectively improved after FRCM strengthening.…”

The fabric-reinforced cementitious matrix (FRCM) has been extensively studied and applied for the strengthening of masonry structures. Special attention needs to be given to the bonding properties between the FRCM and masonry substrate for strengthening applications. This paper presents a statistical analysis of the bonding properties based on the available literature. First, the collected test results were discussed in terms of the interfacial failure mode. Second, the factors influencing the ultimate bond load were analysed based on the different failure modes, and a corresponding prediction formula was further determined via regression analysis for interfacial debonding and slippage failures. Then, the characteristic values of the ultimate bond load were determined via a probabilistic method. Finally, the fracture energy for the slippage failure at the fabric-matrix interface was analysed, and a corresponding prediction formula was obtained via regression analysis. Additionally, some of the collected test results present higher dispersion due to the large variability of the FRCM material properties and the differences in the testing procedures used by different institutions. More studies are needed to improve the reliability of the proposed procedure.

“…Finally, some other authors such as Ismail, et al [13], Kariou, et al [14] and Shabdin, et al [8] carried out flexural strength tests to characterize the effect of the TRM technique in the improvement of the infill panels OOP capacity. This manuscript aims presenting a experimental study to assess the efficiency of using TRMbased strengthening solutions to prevent the out-of-plane collapse of masonry infills in RC buildings.…”
