The main objective of this project is to develop textile reinforced cementitious (TRC) composites and structures in this material that are high-performance, cost-effective and ecological. These new structural systems can only take full advantage of the properties of composites if the material – in particular the reinforcement - is tailored to the structural needs. This project addresses these challenges in six objectives:
- To development high-performance textile reinforced cementitious composites. The requirements for the composite are high tensile and compressive strength. On matrix level this translates to the objective of developing a cement/mortar with good flowability, small grain size, low ecological footprint, wide availability and thus low cost of raw materials -preferentially waste.
- To improve the mechanical performance of cementitious composite materials and structures by optimising the integrated fibre textiles (e.g. 3D textiles).
- To characterise the mechanical performance of the developed TRC composites, and quantify influencial parameters (fibre type & textile, fibre dosage, cement matrix,…).
- To develop new simulation models that support the analysis and design of TRC composite structures.
- To study – experimentally and numerically - sandwich structures with TRC composite faces and insulating core, and explore measures to structurally optimise these systems (e.g. by the use of tailored 3D textiles), for application in low-energy multi-storey buildings.
- To structurally analyse columns reinforced with TRC composite formwork, as a way to reduce the amount of concrete and steel, and increase the durability. These TRC formwork reinforced columns can be integrated into the sandwich elements (5) to create a high-performance loadbearing and insulating structure.
