High performance textile reinforced cements: tensile hardening behaviour and modeling Vrije Universiteit Brussel
Although they offer attractive properties, cementitious materials, as well as ceramics and glasses, are inherently brittle and present a modest and unreliable tensile strength. As such, they are unsuited for structural applications. Cements have a crucial advantage above ceramics and glasses: they are "cold setting", which means that they can be easily strengthened by various reinforcements. In reinforced concrete, steel rebars are offering ...
AE monitoring of 3D textile reinforced cements Vrije Universiteit Brussel
Recently, the textile reinforced cement (TRC) industry has started shifting towards the use of 3D fibre textiles. These 3D TRC’s have a high probability to be absorbed into today’s commercial practice since their manufacturing technique is more closely related to the manufacturing of reinforced concrete elements compared to 2D TRC’s. The considered TRC in this paper is a combination of a 3D AR-glass fibre spacer fabric with a commercially ...
Layered Finite Element (FE) modelling of structural concrete beams non-uniformly reinforced with carbon textile fabrics Vrije Universiteit Brussel
Textile Reinforced Cementitious (TRC) composites can be used as an alternative to traditional load-bearing materials due to their high tuneability, slenderness and freedom-of-form. The modelling of TRCs is traditionally subdivided in discrete and smeared approaches. Discrete approaches model the reinforcement and matrix separately but require a bond characterization whereas smeared approaches distribute the mechanical properties evenly over the ...
Finite element modelling of the material behaviour of glass fibre textile reinforced cementitious composite Vrije Universiteit Brussel
The application of glass fibre textile reinforced cementitious composites (GTRC) in doubly-curved shells has numerous advantages over other widely-used materials for free form shapes. In this paper, the suitability of different material models - available in the finite element programs Ansys and Abaqus - for the modelling of glass textile reinforced cementitious composites is evaluated. The use of the concrete smeared crack model in Abaqus for ...
Use of early acoustic emission to evaluate the structural condition and self-healing performance of textile reinforced cements Vrije Universiteit Brussel University of Antwerp
Textile reinforce cements (TRC) are innovative materials that are used for repair of existing structures or recently as stand-alone lightweight structural members. Fracture and thermal behavior of these materials are very complicated due to multiple failure modes. The undergoing processes cannot be described by the simple constitutive equation. In this perspective the contribution of monitoring techniques is crucial. Acoustic emission (AE) is ...

Tensile behaviour of different high performance fibre reinforced cements Vrije Universiteit Brussel
This paper aims to get insight into the physical significance of the results obtained from curve fitting of a stochastic cracking model on experimental tensile stress-strain data of cementitious composites which are uniaxially reinforced with continuous fibre bundles of different kinds, such as glass, basalt, carbon, polyethylene and polyvinyl alcohol fibres. An experimental test program is performed on the different composites containing ...
Experimental investigation and benchmarking of 3D textile reinforced cementitious composites Vrije Universiteit Brussel
The last couple of years, the importance and potential of textile reinforced cementitious composites (TRC’s) has been investigated and proven in literature. The research has mainly been performed on thin-layered specimens made of individual fibre textile layers impregnated by a matrix. The drawback of this manufacturing technique however is the time-consuming process. A solution is the transition towards a three dimensional, rigid fibre ...
Modeling textile reinforced cementitious composites - effect of elevated temperatures Vrije Universiteit Brussel
The textile reinforced cementitious composites (TRC) used in this study are a combination of inorganic phosphate cement (IPC) with a glass fibre chopped strand mat reinforcement. IPC has been developed at the "Vrije Universiteit Brussel". One of the major benefits of IPC compared to other cementitious materials is the non-alkaline environment of IPC after hardening. For this reason, ordinary E-glass fibres are not attacked by the matrix and can ...
