Bending Behavior

Textile Reinforced Concrete (TRC) can be used as independent structural elements due to its high loading capacity and proper to product light weight and thin walled structural elements. In this study, the bending behavior of TRC plates that reinforced with dry carbon fiber textile and exposed to high temperatures was experimentally studied under 4-points bending loading. The examined parameters were; (a) number of textile fiber reinforcements layers 1, 2 and 3 layers; (b) level of high temperatures 20°C, 200°C, 300°C, and 400°C. Firstly, the mechanical properties of the cementitious matrix and the tensile properties of TRC coupons at each predefined temperature were evaluated. The results showed that the ultimate tensile stress of the TRC coupons did not affect up to 200°C, however, a significant reduction observed at 300°C and 400°C by 19% and 24% respectively. Regarding the compressive strength and flexural strength of the cementitious matrix, the degradation was not severe until 200°C, while it became critical at 400 °C (23% and 22% respectively). The result of the bending of TRC plates showed that doubling and tripling textile fiber reinforcements layers improved the flexural loading. In general, increasing the level of temperatures resulted in decrease in the flexural capacity of TRC plates. The highest decrease recorded for the specimen reinforced with 1-layer of carbon fiber textile subjected to 400 °C and was 33%.

To study the reinforcement effect of textile-reinforced concrete (TRC) on concrete structures in a marine environment, a four-point bending loading method was used for graded loading to analyze the influence of the dry–wet cycle number, the reinforcement method, and chopped fiber addition on the flexural properties of load-holding reinforced concrete beams reinforced with textile-reinforced concrete. The results show that with the increase of dry–wet cycle numbers, the crack width and deflection of beams develop faster and the bearing capacity decreases. The performance of the prefabricated textile-reinforced concrete plate is close to that of a cast-in-place textile-reinforced concrete in limiting crack, bearing capacity, and deflection deformation. The addition of chopped fibers in fine-grained concrete can improve the reinforcement effect of textile-reinforced concrete. Based on the experimental results and referring to the relevant design codes and literature, the calculation formula of the bearing capacity of TRC-strengthened beam with a secondary load is established, and the calculated values are in good agreement with the actual values.

Concrete Elements

In civil engineering, steel reinforced concrete is currently still the most widely used composite material. For broad spectrum of utilization is the most important combination of a high compressive and tensile strength [1]. The increasing demand for subtle concrete elements gave impetus to the development of the new materials for the reinforcement of concrete which are non-corrodible and thus do not need such a thick coating layer-technical textiles. These composite materials are known under the title Textile Reinforced Concrete – TRC. The current research reported the use of AR glass fibers reinforced material for HPC and comparison with other reinforced materials.

Physical Changes

This contribution will introduce carbon-reinforced concrete components (so-called carbon concrete composites, or C3) with sensor functionalities for innovative building envelopes. For a continuous in situ structural monitoring, these textile-reinforced concrete components are equipped with textile sensor networks consisting of resistive carbon fiber sensors (CFSs), which are integrated into the carbon fiber non-crimp fabrics of the concrete reinforcement by multiaxial warp-knitting. The in situ CFSs, consisting of 1 k or 50 k carbon fiber roving with added staple fiber/multifilament dielectric cladding, are later integral to the load-distributing elements of the concrete component, and elongations within these are easy to record with good correlation to ohmic resistance changes. Gage factors of k = 0.52–1.23 at linearity deviations of ALin = 4.0–8.7% are feasible. This allows a monitoring of C3 building envelopes for structural mechanical changes caused by physical changes within the component through mechanical or thermal loads or deformation and cracks.

This study investigates the compressive strength, flexural strength and flexural modulus of the short-chopped igneous fiber reinforced concrete, short-chopped carbon fiber reinforced concrete and plain concrete. Experimental results show that both short-chopped igneous fiber and carbon fiber can improve the compressive strength and flexural behavior of the concrete significantly, and the reinforcing effectiveness of igneous fiber is better that of carbon fiber.
