“…The three different types of basalt mesh and carbon mesh corresponding to mesh sizes of 16x12 mm, 25x25 mm, and 37x37 mm were used in this study. The yarns in both directions of basalt textiles were co mposed of 2400 individual filaments and density of 2.75 g/cm 3 . The carbon meshes with open size 16x12 mm were made up of 48000 individual filaments for the yarns in the longitudinal direct ion and 12000 indiv idual filaments for yarns in the transverse direction, while the other two types of carbon mesh were made up of 48000 indiv idual filaments for yarns in both directions, and density of 1.8 g/cm 3 .…”

This paper describes an investigation of four-point flexural behavior of geopolymer composite specimens which made of textile reinforced geopolymer mortar. The two different types of mesh (basalt and carbon mesh) and their various aperture sizes we re used as reinforcement. In this experimental work, only two mesh layers (for each type of textile) reinforced in geopolymer mortar are considered. All 21 plate specimens including reference specimens, each of size 360x180x20 mm 3 , have been tested for four-point bending strength. Besides that, 15 samples with dimension 30x30x150 mm 3 and 15 samples of diameter size 45 mm x l ength 90 mm have been measured for evaluating the mechanical properties of geopolymer mortar matrix. The results have shown that geopolymer composite specimens with carbon meshes have both the flexural strength and deflection higher than those with basalt meshes. Besides, the decrease of aperture size of mesh improves significantly the flexural strength due to increase specified number of yarns.

“…This is due to the favourable properties offered by TRC, such as its resistance to corrosion, its high strength to weight ratio, its ease and speed of application and the minimum change in geometry. Furthermore, TRC composites are also considered when manufacturing lightweight concrete structures or prefabricated sandwich panels with outstanding mechanical performance, and high-performance concrete construction with free-form designs [7][8][9][10][11][12][13][14][15] A textile reinforced geopolymer (TRG) is a relatively new composite material. To date, many works have been performed to evaluate the effectiveness of the use of a textile reinforced geopolymer matrix composite for the external strengthening layer of existing structure members [16][17][18][19][20][21][22][23][24].…”

In this paper, the results of an experimental investigation on the flexural behaviour, the mechanical properties, and the failure mode of a carbon textile reinforced geopolymer mortar composite subjected to four-point bending test are presented. The influence of various factors such as the type of the carbon fibre fabric, reinforcement ratio, dosage of the chopped basalt fibre on the flexural performance of the reinforced geopolymer composite is experimentally studied. The results reveal that the use of carbon fibre fabrics in the production of high-strength geopolymer matrix composites makes it possible for them to achieve a relatively high mechanical strength. Moreover, the value of the flexural strength and flexural toughness is strongly influenced by the reinforcement ratio and the mechanical properties of the fibre yarn of the carbon textile. The addition of the chopped basalt fibre (BF) plays an important role in both the improved mechanical strength and the failure mode of the geopolymer textile composites. The failure mode of all the specimens shows either a pure bending failure or a peeling off the concrete at the matrix/fibre interface due to the rupture of some filaments in the outer layer and the loss of the bonding strength of the fibre yarn in the matrix leading to the slippage of the fibre yarns within the matrix.

“…A major field of application of high performance concrete in combination with FRP as mesh reinforcement, so-called textile reinforced concrete (TRC), [29][30][31][32][33][34][35][36][37][38][39][40][41] is the utilization for innovative sandwich panels. [42][43][44][45][46][47][48][49] This construction method combines the advantages of light-weight sandwich panels with metal facings and load-bearing elements with thick RC facings. Hence, a new construction method for modern building envelopes is provided.…”

Sandwich‐structured composites represent an efficient method to establish building envelopes which concurrently satisfy several demands. Besides low self‐weight with high load‐bearing capacity, sandwich panels provide sufficient physical properties, such as heat and sound insulation. In general, sandwich panels for applications in building industry are made of flat or thin profiled metal sheets or thick concrete facings. However, standard elements are limited to short spans. In contrast, spatially shaped concrete structures with folded plate or curved geometry provide high stiffness and load‐carrying capacity even for thin elements. The application of folded plate and curved concrete structures to sandwich panels combines the advantages of both construction methods. To realize thin facings in various shapes, high performance cementitious composites are advantageous. Ultra‐high performance fiber reinforced concrete (UHPFRC) provides high compressive and tensile strengths with ductile material behavior. The application of non‐corrosive reinforcement, for example, carbon fiber reinforced polymer (CFRP), allows for filigree concrete elements with a thin concrete cover to only fulfill bond requirements. For sandwich panels with folded plate or curved facings, new production methods are necessary to account for cross‐sections in various shapes. This paper introduces the basic ideas of non‐planar concrete sandwich elements for long‐span roof structures and the developed production methods.
