Investigation was carried out under laboratory conditions on thin elements made from ultra-high performance concrete reinforced by a textile glass mat. The concrete had a fine-grained matrix according to a recipe designed at the Klokner Institute. Thin-walled test specimens were subjected to a short-term load in the testing machine and also to a long-term permanent load. The 2D glass textile reinforcement was protected by an alkali-resistant treatment. The test specimens were loaded in four-point bending. The material properties of the matrix and of the glass reinforcements were determined by a number of accompanying tests. A comparison was made between the results of the experimental investigation and the results of a simulation based on a numerical model.
