Understanding the influence of externally bonded TRC on the cracking behaviour of a plain concrete beam Vrije Universiteit Brussel
In the last decennia there is an increasing interest in the use of external reinforcement for concrete structures made of both Fibre Reinforced Polymers (FRP) and Textile Reinforced Cementitious composites (TRC). Especially for TRC, one of the main applications could be the crack control within the concrete substrate. Despite numerous studies in this field, the influence of an external TRC layer on the cracking behaviour of the concrete ...
NDT inspection on TRC and precast concrete sandwich panels: A review Vrije Universiteit Brussel
Textile Reinforced Cementitious (TRC) composites have gained recent
ttention due to several advantages compared to traditional steel-reinforced concrete, such as concrete usage reductions and design freedom. The
mplementation of this technology on a sandwich design offers light-weight
nd slender structural elements with superior mechanical performance. espite their advantages, they exhibit a complicated structural and ...

Comparison between TRC and CFRP as external reinforcement for plain concrete beams Vrije Universiteit Brussel
Strengthening and repairing existing structures is often more economical and sustainable than demolishing and afterwards rebuilding them. Concrete structures can be strengthened using high performance glass fibre Textile Reinforced Cements (TRC) as an external reinforcement. Until now no evaluation of the cracking behaviour of this system with respect to the established technique of CFRP strips is reported. This paper presents the experimental ...
Study of the crack pattern and its evolution by DIC of RC beams externally reinforced with TRC and CFRP Vrije Universiteit Brussel
Textile Reinforced Cements (TRC) are emerging as an external reinforcing material for concrete structures. Especially the high fibre volume fraction TRCs are investigated by researchers as an alternative for the already established Carbon Fibre Reinforced Polymer (CFRP) strips due to their high mechanical performances, their advantages related to fire safety and their relatively low cost. The application of an external bending rein-forcement on ...
Bending Monitoring of TRC Sandwich Beams by Means of Multimodal NDTs Vrije Universiteit Brussel
Textile Reinforced Cementitious (TRC) sandwich composites consist of two thin TRC facings and a thick insulating core. The thickness of the insulation, that
separates the TRC facings, increases the moment of inertia of the composite, benefiting the bending stiffness and loadbearing capacity. However, due to its composite nature, the fracture under service loads is very complex, where a weak interlaminar bond may reduce substantially the ...

Evaluation of the FIB bulletin 14 design guideline for external TRC bending reinforcement Vrije Universiteit Brussel
Due to their advantages related to fire safety and their relatively low cost, Textile Reinforced Cement (TRC) composites are emerging as external reinforcing materials for concrete structures. The current design guidelines for external reinforcement are mostly elaborated for the Carbon Fibre Reinforced Polymers (CFRP) material solutions. Considering the major differences between both the CFRP and TRC materials, the validity of these CFRP design ...
Influence of Discrete Spacers and Anchorage Length in Long TRC Elements Vrije Universiteit Brussel
Discrete spacers can be used to connect planar textile layers and create pseudo-3D textile architectures for concrete reinforcement. Preliminary studies on short TRC (textile reinforced cement/concrete) beams have shown that on top of the manufacturing advantages, the use of discrete spacers can lead to improved textile anchorage, resulting in increased mechanical performance of the TRCs. Investigations on the effect of the anchorage length and ...
Stay-in-Place Formwork of TRC Designed as Shear Reinforcement for Concrete Beams Vrije Universiteit Brussel
In order to reduce on-site building time, the construction industry shows an increasing interest in stay-in-place formwork with a reinforcement function after concrete hardening, such as CFRP formwork confinement for columns. The current combined systems however do not answer the demand of the building industry for a material system that is both lightweight and fire safe. High performance textile reinforced cement (TRC) composites can address ...
Bending of beams externally reinforced with TRC and CFRP monitored by DIC and AE. Vrije Universiteit Brussel
Strengthening and repairing existing reinforced concrete structures is often more economical and sustainable than rebuilding them. The most commonly used technique, externally bonded Carbon Fibre Reinforced Polymers (CFRP), does not answer the need for a temperature resistant, fire safe and economical solution. High performance glass fibre Textile Reinforced Cements (TRC) can offer an answer to these drawbacks. A validation of this TRC technique ...
