Experimental and theoretical investigations on the high-temperature behavior of fine-grained concrete and textile yarns
The design of structural members under fire attack is an important aspect for safe constructions. For the innovative material textile reinforced concrete (TRC), which is a composite material made of fine-grained concrete and textile reinforcement, the fire behavior has not been investigated intensely yet. Especially the load-bearing behavior of the single components under hightemperature marks a gap in the state-of-the-art of science and technology today. This article deals with experimental investigations on a fine-grained concrete matrix, which has a maximum grain size of only 0.6 mm, as well as yarns made of ARglass and carbon. On the basis of transient tests the stress and strain behavior under high temperatures is derived. Finally, a calculative approach for the high-temperature behavior is suggested.
