Ultra-high performance concrete – experimental testing of bond behavior in variable condition

Popis výsledku v původním jazyce

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 (reinforcing, prestressing) and UHPC and comparison to bond behaviour of ordinary concrete were examined. UHPC 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 in the related experimental works. For reliable transfer of the forces the reinforcement need to be anchored to a sufficient anchorage legth and protected by sufficient concrete cover. This article deals with bond behaviour of embedded steel ribbed reinforcement and prestressing steel in UHPC in variable condi-tions (small concrete cover, diffrerent anchorage length, age) and summarizes previous research.
