Behaviour of beams made in textile reinforced mineral matrix composites, an experimental study

Influence of Ground Temperature on Shotcrete-to-Rock Adhesion in Tunnels

“…e relevant parameters of the calculation are as follows ( Table 7). rough calculation and comparison of the results, it can be seen that the amount of refrigerant required for not providing the heat insulation layer is larger than that of the setting, and the amount of refrigerant required for styrene as the heat insulation layer is larger than that of the polyurethane [83][84][85][86][87][88][89]. In addition, the phase transition point of liquid nitrogen is lower than that of ice, and the cooling effect as a refrigerant is better than that of ice, but the production cost of liquid nitrogen is higher than that of ice (Tables 8 and 9) [90-103].…”

Form finding methodology for force-modelled anticlastic shells in glass fibre textile reinforced cement composites

“…The development of Textile Reinforced Cement (TRC) composites addresses this need by impregnating continuous fibre systems, called textiles, with a cement or fine grained mortar. Whether containing continuous or discontinuous fibres, strictly aligned or randomly oriented, these continuous textiles provide a more orientation-controlled and significantly higher fibre volume fraction reinforcement for cement or concrete than discontinuous fibre systems such as in HPFRCC [8,9]. As in shells the stress directions vary with the applied loads, the used textiles are randomly oriented chopped fibre mats.…”

“…Producing and subsequently stacking individual laminates of 1 mm thickness, the shell thickness is well controlled during manufacturing and a low thickness tolerance (1 mm) can be assumed. Numerous building applications, such as sandwich panels for bridge design [19], hollow beams [9] and lightweight firewalls as shown in Fig. 1 [20], benefit from the structural yet fire resistant properties of this ceramic matrix composite.…”

“…The use of continuous fibre systems, called textiles [8,9], allows the impregnation of much higher fibre volume fractions if the grain size and rheology of the cement matrix is adapted to the high density of the textile [8]. Researchers at the Vrije Universiteit Brussel developed a fine grained cement matrix, Inorganic Phosphate Cement, that can impregnate dense glass fibre textiles up to 20% fibre volume fraction and more [10], resulting in a high tensile capacity while making any other reinforcement, like steel, redundant.…”

A state of art of review on strengthening of concrete structures using fabric reinforced cementitious matrix

“…To surmount this hurdle, a breakthrough was achieved by substituting continuous fiber sheets with textiles, leading to improved bonding between fibers and the mortar-based matrix [8]. These novel composite materials were named as Fabric Reinforced Cementitious Matrix (FRCM) or Textile Reinforced Mortar (TRM) [17] [18].The utilization of mortar rather than epoxy elevates heat and fire resistance while improving concrete substrate compatibility [19] [20].
