Effect of Temperature Increasing on Deformation Properties of TRC

Abstract:

This paper presents a description of the changes in the deformation properties of TRC under a gradual increase in temperature. TRC [1, 2] is a composite material consisting of a fine-grained UHPC matrix and textile glass fibres, known as AR-Glass. A very high load-bearing composite can be produced by combining the high compressive strength of UHPC (approximately 150 MPa) and the high tensile strength of textile glass fibres (about 2200 MPa). Samples 1100 x 120 x 20 mm in size were produced for the experiment. The samples were placed in a thermal chamber and were submitted to a constant load. In the next step, a gradual increase in temperature up to 75oC was simulated using heating cables located on the bottom of the chamber. We monitored the changes in bending in the middle of the span. Since the experiments are very time-consuming, the experiment was also simulated using a numerical model. Finally, there is a qualitative comparison of the two methods.
