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 ...
LAYERED FINITE ELEMENT (FE) MODELLING OF CEMENT COMPOSITES COMBINING CONTINUOUS TEXTILES AND SYNTHETIC MICROFIBRES: A FLEXURAL ANALYSIS Vrije Universiteit Brussel
This research presents a layered, semi-smeared modelling approach for the prediction of the flexural response of Textile Reinforced Cement (TRC) beams with combined continuous textiles (0.7v%) and short microfibres (1%). The constitutive behaviour of the composites was obtained from tensile experiments on TRC configurations and subsequently implemented in two different smearing approaches. The first approach concentrated the cross-sectional ...
Finite element analysis of glass fibre reinforced composites with inorganic phosphate cement matrix: comparison of inbuilt abaqus concrete models. Vrije Universiteit Brussel
Cement composites are promising particularly for the construction industry as they overcome crucial drawbacks of more commonly used polymer matrix composite materials. Contrarily to traditional organic resins (epoxy), the Inorganic Phosphate Cement (IPC), developed at Vrije Universiteit Brussel, is incombustible. The IPC matrix moreover has a neutral pH after hardening, such that it is not chemically aggressive for E-glass fibres, which are ...
Mechanical behavior of cement composites reinforced by aligned Enset fibers Vrije Universiteit Brussel
Driven by the search towards new materials with reduced ecological impact, several investigations on plant- based natural fibers for composite reinforcement have been undertaken by researchers in the past decades. However, Ensete Ventricosum (Ev) fiber as reinforcement in a cementitious matrix has not yet been studied. This research aims to assess the mechanical performance of aligned Ev fiber reinforced cementitious composites and particularly ...
Spacers for 3D Textiles as Reinforcement in Cement Composites: Influence on the Flexural and Cracking Behavior Vrije Universiteit Brussel
Discrete spacers allow to transversally connect planar textiles and to transform them into pseudo-3D architectures. These 3D textiles can provide the optimal reinforcement in cement composites as the concrete casting process is enhanced and the textile placement within the mould is well-controlled. This research investigated the effect of discrete spacer connections on the flexural properties and cracking behaviour of TRCs and performed a ...
Bending fracture of textile reinforced cement laminates monitored by acoustic emission: influence of aspect ratio Vrije Universiteit Brussel Universiteit Antwerpen
Textile reinforced cement based composites (TRC) are a new class of sustainable construction materials
with superior tensile strength and ductility. These materials have the potential for becoming load bearing
structural members, therefore a wide array of structural and non-structural applications are possible.
However, their heterogeneous, laminated, ?brous nature complicates the understanding of their fracture

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 ...
Applicability of composite Charpy impact method for strain hardening textile reinforced cementitious composites Vrije Universiteit Brussel
Since most test methods, used for strain hardening cementitious composites, are adopted from polymer composites test standards, this paper investigates the applicability of a standard impact test (ISO 179-1:2000), which is used in the polymer composites world, on a specific textile reinforced cementitious composite using an inorganic phosphate cement (IPC) as a matrix material. The aim is to provide a test method to investigate the local impact ...
A layered-wise, composite modelling approach for fibre textile reinforced cementitious composites Vrije Universiteit Brussel
Textile Reinforced Cements (TRCs) offer an adequate alternative to more conventional building systems in construction due to their tunable and lightweight geometries. TRCs are currently either modelled by means of a discrete approach, where the textiles and the matrix are modelled separately, or by means of a smeared approach that averages the material's mechanical response over the cross-section. The research presented in this paper proposes ...
