New materials require extensive research. Ultra high performance concrete is relatively modern cementitious material with favourable material properties. In previous research a lot of different mixtures of UHPC and many important properties were developed and tested as a basis for upcoming numerical analysis. Especially bond behaviour between steel and UHPC and comparison to bond behaviour of ordinary concrete were examined. UHPC has significant better material properties, especially bond behaviour, and represent an alternative material for some steel structures which can satisfy in some cases the requirements on construction dimension and economy. The function of the constructions details using small anchorage length was experimentally verified too. For reliable transfer of the forces the reinforcement need to be protected by sufficient concrete cover. This article deals with bond behaviour of embedded steel ribbed reinforcement in UHPC with small concrete cover and summarizes previous research results in field of the bond of UHPC. |
